Have you ever wondered about the process of renting a crane? There are many different types of cranes and a wide variety of things they can be used for. Knowing which kind of crane is most fitting for the job you need is your first step. Let’s say you are a landscaper; a crane is a perfect addition to the tools and equipment you already use. A crane will give you the extra height you need to trim, cut or prune those super tall trees. It will give the gardener a lift or the crane can be used to lift the tree itself. Crane services are ideal and very necessary for most landscapers who are hired for big estates, schools or industrial properties. There is a lot of ground needed to be covered and many things must be lifted or hauled that a person can’t do with their strength alone.

A crane service is great because it enables work to be done in a shorter time frame than it would with the strength of manpower alone. That is when a crane service comes in to play. You would contact a company like Sheedy Crane to come and estimate the job you wish to accomplish. They would examine all the aspects of the job you’re hiring them for, the time frame needed, and the weight of the lifting. Then, they would suggest the best crane for that specific task. Since cranes specialize in hauling, lifting, hoisting and other actions that are related to landscaping, you’ve selected the perfect machine all in one. Keep in mind that crane services are by no means limited to landscaping. They are used for many more tasks as listed in greater lengths on the website. Read on to learn about the process of renting a crane.

Selecting your ideal crane

Sheedy has many cranes available for rental.

Cranes are designed to do many things for a vast amount of activities. It’s an all in one tool. There are also many add on features that can be attached to the crane itself to increase its ability. Crane companies know each crane inside and out and are the best ones to ask questions about before you begin your project. Cranes vary depending on what amount of weight they are able to pick up, move or hold. Crane services are measured by the ton, and range from 500 tons, to as little as a 10-ton load, and smaller. A landscaper would most likely require the power of a 10-ton crane, such as a rough terrain crane or a Hydraulic crane. A consumer in the landscape field would probably be interested in a crane that comes equipped with a man-basket, which would enable easier pruning services, spreader bars, pallet forks, and more. A good crane candidate would also be a hydraulic truck crane when it comes to landscaping projects if it entails moving stones or uprooting trees. Again, the crane rental service or local crane company would be the right ones to identify the ideal crane for your desired job. Perhaps the project for which you need a crane services requires the use of two cranes at once or two different cranes. Both scenarios are possible with Sheedy Crane.

Before any of our operators set foot on a work-site, our engineers have evaluated every aspect of a proposed project. With safety in mind, we plan for all possible scenarios based on the load, route, and projected lift. Our civil and building engineers use 2D and 3D CAD designs to predict exactly how a heavy hauling/lifting operation will function in the real world. This enhances the predictability, precision, and productivity of everyone involved in the project. Our engineering services in the San Francisco Bay Area help facilitate heavy lifts, heavy hauling, structural shoring, seismic retrofitting, and hoist services around the Western United States. Read on for considerations for heavy hauling projects.

Heavy Hauling Engineering

Our team of experienced operators and engineers are responsible for some very impressive feats of modern technology, physics, and engineering. For example, a dual-lane heavy haul of a refinery pressure vessel for the Diablo Canyon Power Plant required careful logistical and safety planning. Hundreds of thousands of pounds had to be moved countless miles through the roads of California; this entailed careful route planning and proper engineering precautions. Many aspects of a project need to be taken into account whenever planning for a heavy haul, such as:

  • The weight limit of the roads on a proposed route
  • The weight of the refinery pressure vessel
  • The weight limit of all heavy hauling equipment, including trailers, trucks, cranes, and the equipment used to secure the item to the bed of the trailer
  • Maximum MPH of the transporting vehicle
  • Safe securing of the load and proper weight testing
  • Possible construction of temporary structures to facilitate the transport of the item
  • Heavy and over-dimensional cargo tie-down and planning
  • Engineered critical lift planning

This project helped facilitate upgrades to the Diablo Canyon Power Plant, a facility that is responsible for 8.6% of total California power generation and 23% of the state’s carbon-free generation. This power plant supplies the electrical needs to more than 3 million people; with a job this large, errors in safety planning and engineering calculations are simply not an option.

Other Considerations for Heavy Haul Engineers

When engineering a safe route for a heavy haul, engineers don’t just take the weight limit of certain roads into account; engineers also must plan for any obstructions on the proposed route. Here are just a few obstructions that we’ve encountered on routine route planning:

  • Bridges: Measuring bridges and obtaining weight limits is incredibly important. Some states do not have the height limits recorded for certain bridges, so it may be necessary to have an engineer measure the dimensions of any and all bridges before the route is approved.
  • Trees: If a tree is obstructing a proposed route, permission is required to have a tree trimmed or cut down. Older trees may be protected by state laws; if this is the case, the tree may have to be tied down, or another route must be planned.
  • Wires: If utility or electrical wires are obstructing a route, a utility or electrical company must be contracted to help temporarily move the wires. Other considerations, such as traffic safety and control, must be taken into account. This generally requires working with local police to ensure the safety of all bystanders and operators.
  • Railroad Crossings: If a load is particularly heavy, a truck may not be moving more than 5-10 MPH at any given time (or even slower). Owners of the railroad must be contacted to ensure a proper amount of leeway when crossing certain tracks.
  • Signal Lights and Signs: If traffic lights or overhanging signs are blocking the proposed route, light contractors, state entities, and other service professionals will need to assist with the heavy haul.

Clearance laws are different for every state and generally come in either 2in or 6in clearance variants. This just means that there needs to be at least two inches or six inches between the top of the load and the highest point on the bridge. Other federal regulations for weight limits on federal highways and interstates and service roads must also be honored, and permits must be obtained if load limits exceed the usual weight capacity.

Each year, southern California experiences an estimated 10,000 earthquakes. The majority of earthquakes are so small that they are never felt on the surface and only several hundred of these are greater than a magnitude of 3.0. About 15-20 of these earthquakes reach a magnitude of 4.0. Generally, the aftershock of a large earthquake can produce a number of earthquakes of varying magnitudes for many months after the initial earthquake.

Due to the amount of earthquakes in California, seismic base isolation has become a relatively new retrofitting technique that helps provide a structure more flexibility to withstand the lateral forces of an earthquake. Base isolators act like large “motor mounts” when placed under a load-bearing column of a bridge or building and, during a seismic event, the isolators absorb the impact which reduces the seismic forces transmitted through the building. Seismic upgrades are a necessary repair to old, historical structures. Often times, the technology to protect against seismic events simply did not exist when the historical structure was built.

construction site

Seismic Retrofitting

The process of seismic retrofitting strengthens weak connections found in roof to wall connections, shear walls, roof diaphragms, and continuity ties in existing buildings. Building codes were much less stringent until 1998, when past structural codes and requirements were updated to support the safety of the occupants and integrity of the structure.

Reasons for Seismic Retrofitting

The process of seismic retrofitting is performed for a number of reasons; the key motive is to ensure the structural security of a building’s machinery, inventory, and employees.

  • Improve the marketability of a building.

The probable maximum loss (PML) of a building is determined using a number of factors when buyers are looking at real estate. Structural integrity of a building is greatly improved when the base of a building is stabilized using seismic retrofitting. Buyers are more inclined to buy a property that will provide more security and less liability to themselves and their tenants. The number of lenders will increase when your building is safe, which will result in more buyers of the property.

  • Reduced potential for legal litigation and injury

In the event of a building collapse, an owner can lose a significant amount of money if it can be proven – through litigation – that a building was in need of structural repair and they did nothing to remedy the situation. Insurance coverage means nothing against a successful negligence litigation. Seismic retrofitting ensures that a property owner will not be held liable for negligence, making the purchase of said real estate an attractive choice.

  • Increased Safety of the Tenants

Who wants to live or operate a business in a building that has not been proven to be structurally sound? A building upgraded with seismic retrofitting results in tenants staying for longer periods of time due to peace of mind and an increased sense of security.

  • Insurance Companies

Rates for insurance claims regarding earthquakes have increased 3-to-6-fold since 2005. In the future, many insurance companies may not write coverage for earthquakes if the owner did not take all the proper steps to ensure the structural integrity of the building.

Planning a safe crane lift takes a staff of trained engineers, riggers, and operators to get the job done. Calculating the details of a lift, the load and counter-weights required, how the crane will operate during the lift, what equipment and personnel to use, and how each part of the lift will be carried out are all necessary elements that must be understood by all crew members and project managers to ensure a safe and effective lift.

The first priority of any crane operation should be the safety of all personnel and civilian lives in the area. Working with heavy loads is serious business that leaves no room for error; having a proper lift plan in place will ensure the safety of everyone involved.

Critical Lift Planning

Engineers use a number of different strategies to plan a lift. Custom 2D and 3D CAD support can help the team involved with the lift visualize the task-at-hand. Conceptual drawings, designs, and proper calculations will put the team and the client at ease while ensuring maximum productivity and safety of the lift.  There are many standards set by OSHA (The Occupational Safety and Health Administration of the U.S. Department of Labor) that our engineers follow to protect crew, equipment, and avoid any potential accidents. Here are just a few steps our engineers take when planning a critical lift:

  1. Quote and Assess the Project

During the first stage of any project that requires crane lifting, crane engineers must assess the job, provide proper lift calculations, potentially utilize CAD drawings, and evaluate any potential challenges associated with the lift. Is the job located in a heavily populated metropolitan area? Will the crane have to be heavy-hauled to a remote location? What is the estimated budget of the project? There are a number of considerations that go into each unique project.

  1. Visit the Proposed Job Site

Once the logistics of the job are settled, engineers will visit the site to assess the terrain, ground condition, restrictions of the area, nearby overhead structures, and how difficult the area is to access. If a heavy haul is required to the site, additional route planning must take place to ensure the safe delivery of an oversized load.

  1. Calculating Crane Load and Equipment

After data on the job site is collected, important figures are calculated concerning the center of gravity, load weight, and shape of the object to be lifted. Once these calculations are made, engineers will select the type of crane and equipment they’ll need to get the job done. Other important considerations that engineers think about are:

  • How much space does the crane arm need to swing safely?
  • How much can the crane lift at any given time?
  • How much will the counterweight of the crane need to weight to prevent a crane topple?
  • Where should the crane be placed at the job site?
  • Will obstructions need to be moved before the crane is placed?
  • What crane will be compatible with the given terrain?
  • What is the proper weight load of the rigging required?
  • How much ground area needs to be blocked off for civilian and crew member safety?
  1. Technical and CAD Drawings

Engineers will provide blueprints of the project to ensure that everyone is on the same page before, during, and after the lift. A technical drawing will illustrate where the crane will be placed, how to avoid any potential obstacles, and how the lift will be safely conducted.

construction worker

  1. Final Steps Before the Lift

All equipment should be inspected prior to the lift as part of a standard safety inspection. All equipment should be thoroughly examined, oiled, maintained, and repaired prior to any job (regardless of how large or small the project is). Supervisors will brief the team on proper safety protocols and use the technical drawings laid out by the engineers as the roadmap for a successful project; a reliable system of communication (such as a hands-free system) will also be in place to ensure proper communication between the crane operator, the supervisor, and the rest of the crew.

Cranes allow operators to lift loads which would otherwise be impossible or impractical to move using regular manpower. Smaller cranes rely on electric or diesel-powered motors along with hoists and pulleys to lift and move objects. For bigger, multi-ton loads, however, hydraulic cranes are the industry go-to. These hydraulic behemoths can lift thousands upon thousands of pounds by transmitting forces through hydraulics. These cranes can be used for disaster relief, construction, and even wildlife management. With the help of hydraulic cranes and experienced operators, a staggering feat of engineering can be accomplished.

How Do Hydraulic Cranes Work?

The central concept behind a hydraulic system involves the transmission of forces from point A to point B through an incompressible fluid. A crane’s engine powers the hydraulic pump, which applies the necessary pressure in a hydraulically operated system. This pressure is redirected in the hydraulic system to the desired location. This is done using a system of pistons. In a simple hydraulic system, one piston pushes down on the hydraulic fluid and the force is transmitted through the fluid to another piston, which is pushed up. These piston rods are what you see when a hydraulic crane boom is raised, lowered or telescoped. The pistons are doing the work on the hydraulic fluid, which is transmitting the force.

Hydraulic Fluid Basicscrane

The hydraulic fluid used must have certain properties. First and foremost, it must be incompressible- meaning it does not reduce in volume when great pressure is applied. Water and mineral oil are traditional hydraulic fluids, and the first hydraulic systems and cranes were water-based. Hydraulic fluids are at their maximum density- no application of external force will cause them to compress and become denser. This is important for full transmission of force. A compressible fluid will not completely transfer the force applied at point A to point B; there will be a reduction proportionate to the compressibility of the fluid.

Other properties found in modern hydraulic fluids include low volatility (low tendency to vaporize), low foaming tendency, and proper viscosity. Special applications may also require fire resistance, low toxicity, oxidative stability and thermal control. Modern hydraulic cranes run on oil-based hydraulic fluid with appropriate additives. These provide both power conveyance as well as lubrication for the piston and piston rods.

Hydraulic Power

Hydraulic pumps are powered by the gears in the hydraulic pump. There are two basic types: gear pumps and variable-displacement pumps. Gear pumps involve a pair of intermeshing gears which pressurize the oil, but have a drawback. The pressure in a gear pump will increase or decrease in response to engine speed. High pressure in a gear pump can only be attained by running the engine at full power, and the power output is harder to control as a result.

Variable displacement pumps, on the other hand, are what is used in load-sensing hydraulic systems. This is the more modern approach to hydraulic systems in cranes. These are more efficient and complex systems, because they make use of a swash plate to adjust the amount of oil available to the pump. These variable displacement systems will respond to the load being lifted and make the appropriate amount of hydraulic oil available for the pistons and rams. This reduces fuel consumption and adds a measure of safety.

Hydraulic Cranes in Action

Hydraulic cranes allow us to use this intelligent and powerful system to accomplish a great range of feats. Cranes with hydraulic capabilities are rated for the lifts they are capable of handling. It’s an easy system to decipher; a 70-ton crane can lift 70 short tons, or 140,000 lbs. This rating is made with a safety margin in mind to prevent tipping. The crane is rated to handle a load usually between 70% and 85% of its maximum capacity.

Cranes with hydraulic capabilities have a large number of applications. Because they are mobile and relatively lightweight, they can be rented to handle heavy loads on a job site. Hydraulic cranes are used to erect buildings and lift multi-ton concrete and rebar bridge beams. They are commonly called upon to rescue other heavy machinery, such as locomotives and heavy trucks. Hydraulic systems are even used to move whales during rescues or relocation.

When most people think of cranes they think of construction (and rightly so!). Cranes are used to lift and move loads which are beyond human ability to transport simply, so they are commonly employed in loading and unloading freight or in material movement during construction. But these traditional and well-known uses of cranes aren’t the whole story. Cranes in film production have a rich and widely varied history and are responsible for many iconic scenes in a countless number of blockbuster films.

Introducing: Crane Shots

The ground-breaking addition of cranes to the repertoire of tools used in film production can be traced back to 1916, with the film Intolerance. This D.W. Griffith silent film features what is widely accepted as the first “crane shot.” The inventor and engineer Allan Dwan, a fellow film director, dreamed up the yet-unheard-of shot for Griffith’s film. The result had an impact, making audience members gasp in wonder from the grandiosity and scale of the sight.

Not long thereafter, camera cranes created to elicit just such a reaction became popular at major movie studios. They were typically produced as massive monstrosities, specialty items created by large ironworks companies. They got bigger and heavier, carrying multiple people and the cumbersome camera equipment of the day. Each crane was built with a specific shot or purpose in mind, and as such their appearance and capabilities varied greatly, while their mobility was limited.

The Camera Crane Revolution

And so it was, for over 20 years in the film industry. Bulky film cranes with little flexibility stayed on studio lots, seldom transported to on-location shoots. That all changed in the late 1940’s, when Ralph Chapman, a special effects technician with a knack for engineering, developed a line of cranes. His gasoline-powered film crane could travel on location independently, revolutionizing the use of exterior crane shots in film. Before long, these mobile crane units were available for hire.

Television and sports soon joined the fray, and the high-angle boom shots became popular in filming dance numbers, creating emotive scenes, and covering sports, much to the delight of audiences. Since the early days of limited, one-off cranes made for particular shots, technology has exploded. Crane capability has vastly improved, alongside the safety-consciousness and expertise of operators. The use of crane shots in both television and film is ubiquitous in the modern era of entertainment.

Film and TV Cranes Today

Studios and production companies generally rent crane equipment from the manufacturers who own them. This cuts down on costs and allows for a variety of cranes to be used on a production. The usage of rented cranes in film and production has seen a decline in recent years, as the introduction of drones and light-weight digital cameras have revolutionized the industry. Despite this shift, there will no doubt always be room for the silent, sweeping shots which can only be obtained by the massive cranes originally designed decades ago. They are a part of the history and future of the crane industry, and will help tell stories in a way nothing else can for years to come.

Heavy hauling and over-sized loads present a number of safety and logistical considerations when preparing the haul. Careful planning and execution is necessary to prevent any injury or collateral damage on the highway and at the work site. Here are a few tips for over-sized loads and heavy hauling.

  1. Choose a Company with a Proven Track Record

When it comes to oversized loads, you want a company with a proven track record for success. A company like Sheedy has been in the business for over 88 years, with a track record of performing some of the most challenging overweight and over-dimensional cargo hauling projects in the country. When it comes to heavy hauling, it does not pay to cut corners.

  1. Choose Your Driver

All drivers that operate a vehicle for heavy hauling should be trained and experienced in securing loads safely. They should also be adept at the equipment they are operating. There is no room for error when it comes to heavy hauling, especially in highly populated areas such as the interstate. All Sheedy drivers are current Transportation Worker Identification Card (TWIC) holders and meet all proper training and safety regulations.

  1. Permitting and Regulation

Make sure to obtain all proper permits that are required for your heavy haul. All equipment over 102” in with will require an oversized permit before it can be driven on highways or state roads. Each state will have certain guidelines regarding oversized loads and loads over 10,000 pounds. Federal regulations are serious business, especially when in it comes to interstate commerce. Local regulations may also apply if the equipment is being hauled intrastate.

  1. Know Your Route

It may not be enough to just run the route on a GPS. A pilot car is a good idea if you are unsure about possible road closures, toll roads, heavy-traffic areas, construction blockages, and other hazardous scenarios. Planning ahead of time can save you time, money, and may save you a headache or two.

  1. Secure Your Load

Over-dimensional loading and unloading is not a subject to be taken lightly or glanced over. Errors at this stage in the process can result in severe injury and damage to equipment, personal property, and roadways. A reputable company will have drivers that are very experienced in this matter.

Shoring, simply put, is the process of temporarily supporting a structure, building, vessel, or trench. Shoring usually occurs when the structure is in danger of collapse, or when repairs are needed to be done to the structure. Structural shoring supports the floors and beams that hold a building up while a wall or column is removed for repair or renovation. Shoring is used to prevent building collapse and to protect workers while they perform their job safely.

Types of Shoring

There are quite a few different types of shoring. Different equipment is used for different loads, materials, and settings.

Raking Shoring

Rakers – also known as scaffolding tubes, are set an incline from the base of the structure to the top of the wall. These rakers provide support in a diagonal manner, with plates mounted to the

ground and the structure itself. Rakers are generally angled from 45-75 degrees and secured with braces that bolt into cleats in the wall at a few given intervals. The strength of the individual scaffolding tubes depends on the amount of weight being distributed by the structure itself.

Flying Shoring

These shores do not touch the ground; rather, they span walls in mid-air to prop them up. A horizontal strut is placed between walls and secured to plates. A network of smaller, shorter beams (also known as needles) attached to steel construction cleats distribute and balance the weight evenly.

Dead Shoring

A system of beams and posts are used in dead shoring to vertically support a building’s roofs and floors by transferring the weight of a structure to the ground and the temporary support structure. The vertical props are braced to sole plates on the ground, with needles securing the tops of the dead shores.

Trench Shoring

A trench may be dug to build new or existing structures beneath a building, such as additional living units, parking garages, or storage spaces. Soldier pile walls are often used to hold the weight of a dug trench while work is performed. H-shaped piles are inserted into holes in the ground a filled with concrete at around 6 to 12 feet intervals. The hole may be around 24” in diameter with the H-pile 10-14” wide or deep. Steel piles may also be used instead of h-piles in the absence of concrete. Between the h-piles are 4×12 horizontal wooden beams to retain and support the weight of the soil behind the wooden beams.

At Sheedy Drayage Co. we are capable of performing almost any hoisting, rigging, or hauling task efficiently and safely. We have an extensive fleet of mobile and specialty cranes to get the job done in any industry. From tanks, refineries, power plants, steel and rebar, and mechanical equipment to emergency assistance or movie and television support, we have decades of experience working with every type of business.

A crane uses a variety of simple machines to create large amounts of support and leverage. Using wire ropes or chains, sheaves, and a hoist rope, cranes can move extremely large and heavy loads that are far beyond the capability of humans. The Ancient Greeks were the first known inventors of the modern construction crane and employed the use of human treadwheels and animals to power the structures. Since then, technology has grown exponentially and so has the use and complexity of cranes. There are hundreds of various crane forms, with each design tailored for a specific use. Our cranes can be used to construct high buildings, while our flying jibs can be used for highly specific purposes, such as getting a load into a building with an overhang.

Anatomy of a Crane

Cranes are a staple of any large construction site. As said above, there are a large variety of crane types; however, they are all engineered to perform a similar task. That is, to lift and move heavy loads. Cranes are generally mobile pieces of equipment due to the fact that they must travel to many different construction sites around the country. If you’ve ever seen one while in operation, maybe you’ve wondered how the metal arm can lift and support a huge amount of weight while not toppling over. There are quite a few engineering and physics feats that go into each lift and having engineers that know the mathematics behind each job is imperative to the success of the job. Some jobs are completed in busy cities with many people around the job site; because of this, error is simply not an option.

The majority of cranes feature a number of pulleys and cables to lift and lower heavy pieces of equipment and material. Think generators, turbines, huge slabs of concrete and other materials that weigh thousands of pounds. Ever wonder how they get those huge glass windows into skyscrapers? The answer is simple: cranes. Here’s the basic anatomy of one:

 

  • The boom – This is what the very end of the crane looks like. It’s the long steel arm that has the hook or another specialized piece of equipment on the end of it.
  • The hook and ball – the shape and size of the hook depend on a few things, such as how much weight the crane is carrying and what industry it is being used for. For example, gigantic steel claws are used in scrap yards to pick up huge amounts of steel debris. For another application, a hook is more suitable for lifting large shipping containers from port to ship.
  • The jib – either connected at the top or end of the boom, its structure carries the load and extends the boom to provide increased mobility. Think of the jib as the wrist and the boom as the arm, with the hook being the fingers of the crane.
  • Counterweight – this is one of the measures used to make sure that the crane does not topple over due to the weight differential. Either found at the base of the crane or near the cab of the crane, these counterbalance the weight being lifted by the boom to ensure the safety of the workers and the construction site.
  • Outriggers – Severe shifts in balance occur when operating a crane, due to the weight of the load. These are used in addition to counterweights to help stabilize the entire crane by using hydraulics to lift the entire crane at once.
