Every day, we get customers who reach out to us to quote a new overhead crane installation. They may be moving into a new building, replacing an old or outdated piece of equipment, or may be buying an overhead crane for the first time and are looking to expand their business’ material handling capabilities. The bottom line is, they’re looking for the cost of an overhead crane.
First, we’ll discuss the factors that affect the cost of any type of overhead crane, and then we’ll dive into the prices of common types, sizes, and configurations of overhead cranes.
To make sure that you get the right type of overhead crane for your business, you should be ready to address the following information when you contact an overhead crane manufacturer to bid on your project:
An overhead crane is a complex piece of equipment, and there are many different types of overhead cranes to choose from. The complexity of the overhead crane components required to operate the crane, the engineering required to design the crane, and the application (industry or materials being lifted) will determine what type of crane you will need.
For example, an 80 foot, 20-ton double girder bridge crane will cost significantly more than a 40 foot, 10-ton double girder bridge crane.
The span, or distance between the runway rails, is one of the biggest contributing factors to the cost of an overhead crane. The longer the crane’s span, the more material is required to build the crane girders. This added material increases the crane’s weight, which will also increase the cost of the runway, if required.
An overhead crane’s capacity is the maximum load which may be applied to the crane in a particular working configuration, and under a particular condition of use.
When the manufacturer comes on-site to provide a consultation, they can calculate the capacity based on their understanding of:
A crane that requires a large capacity, a large span, or severe service classification, may require a double girder design—meaning there are two beams that make up the bridge. These girders can be designed in a rigid welded steel box girder design for added reinforcement. This type of setup will be the most expensive, as there are significant increases in labor and material charges to weld and fabricate the girders.
There are six different classifications of overhead cranes, specified by the Crane Manufacturers Association of Amerika (CMAA). An overhead crane manufacturer will determine what type of crane classification they’ll need to build for your specific lifting application, using the following criteria:
Class A and Class B cranes will be your least expensive option because they’ll be used mostly for maintenance or the initial installation of equipment. They’re used infrequently, and there are long periods of idle time between lifts.
Class C cranes will be a middle-of-the-road type crane. There may be some additional engineering built-in to the project for a specific need, but they typically utilize a basic hoist, trolley, and bridge design. They’re used moderately to handle loads at or around 50% capacity and are in service for about 5 to 10 lifts per hour.
Class D and Class E cranes, often referred to as process cranes, are built for a specific need and are more heavy-duty. They may be constantly running in excess of 50% of the rated capacity, and they’re making 15 or more lifts per hour. They have more engineering or customized solutions built into the design for the specific lifting application—which increases initial design and engineering costs for the project.
Class F cranes must be capable of handling loads approaching rated capacity continuously, under severe service conditions, throughout their lifetime. They’ll be extremely expensive due to additional costs related to design and engineering, sourcing of heavy-duty components, materials and labor, and installation.
A severe, obstructed, or dangerous operating environment where the crane will be installed and running, will affect the cost of an overhead crane in several different ways.Environmental factors such as high heat, the presence of chemicals or fumes, steam, dust, or excess moisture can require special metal coatings to protect and enhance the operating life of the crane. The individual components of the crane will also need to be sourced to ensure that they can hold up and withstand the operating environmentFacilities like wastewater treatment plants, fertilizer plants, and oil and gas processing facilities require explosion proof cranes. This means that the equipment cannot generate any type of spark. These types of cranes can utilize a specific pneumatic air-powered system, or a specially-designed electrical system to make them explosion proof—however, these can be expensive to design and install.
Cranes that will be used outdoors will need additional protective coatings to prevent corrosion and will require weatherproofing to seal out moisture and dust or dirt. Stainless steel or galvanized components will also need to be sourced to ensure that they can handle exposure to the elements and don’t rust.
A dangerous operating environment will also require special equipment and protection (PPE) for the installers during installation. Any obstructions to the installation area can add to the cost if the installers don’t have clear access to the area to remove an existing structure or install a new one.
The runway length is the largest contributor to the runway cost itself. This length can also play into the cost of the crane. If you need to make multiple picks per hour and have a long runway, then you may need a faster trolley and hoist to move up and down the runway quickly. The additional speed may require the components of the crane to be sized to a higher capacity.A faster crane that travels the length of the building may also require the operator to work from within an exposed or enclosed cab—which is more expensive than radio or pendant controls.
If an overhead crane is being installed in a new construction facility, then typically the runway beams will be installed during the construction process, and the crane manufacturer won’t need to include the runway structure in the quotation process. Care must be taken with your construction contractor, as crane runway tolerances are much tighter than standard construction codes. Repairing a runway that is out of tolerance can add significant cost to the installation.
If a crane is being retrofit into an existing building, there will be added costs for the design, fabrication, delivery, and installation of the crane’s runway system.
Most crane manufacturers don’t offer in-house structural repair or certification services, so you’ll also have to consider any additional costs related to having concrete contractors or structural engineers provide a consultation of your facility. They’ll need to determine if the existing building structure and foundation can handle the additional loads generated by the installation of an overhead crane system.
As you can see, there are so many different factors that can affect the price that you’ll pay for an overhead crane system. The two most important aspects are span and capacity. These will determine how much labor and material will be required for the project, and will also dictate the complexity and design of the hoist, trolley, bridge, controls, and power system—all major players in how much a crane will cost you.
