What Are Crane Parts?
Crane parts are components that make up the structure, function, and movement of a crane. They are designed to work in unison to lift and move heavy loads safely and efficiently. Without these crane parts, the crane would not be able to perform its intended function.
Hoists and Trolleys
The hoist and trolley work together to lift and move loads. As the hoist uses ropes or chains to lift, lower, and hold the load, the trolley connects the hoist to the bridge and allows it to move horizontally. Depending on the type of crane, the trolley can be located on the top or the bottom of the bridge. Additionally, both hoists and trolleys are available with manual or powered operation. These two components get your load from point A to point.
Bridges
The bridge is the component that allows you to move loads along the length of your facility. This bridge is supported by the runways and includes several elements that allow it to function. Bridge components include:
●The bridge beam: The bridge itself is made of one or two beams supported at each end by the two runways.
●The end trucks: The end trucks are connected to both ends of the bridge and use wheels to carry it along the runways.
●The drive: The bridge drive is an optional electric component that powers the bridge’s back-and-forth movement over the runways.
Runways
A crane’s runways support the bridge, which holds the trolley and hoist. The runways are constructed from beams or enclosed track to allow the bridge to move along the length of the crane. They are installed throughout your facility, with runways placed to reach every area you need to cover. As the crane operator picks up loads with the crane, they can move the bridge back and forth over the runway. Then, they can move the trolley and hoist to place the load in the correct spot.
This part of the machinery will differ depending on what type of overhead bridge crane you install. High-capacity applications may require top-running bridge cranes, where the bridge runs on the top surface of the beams. Alternatively, bottom-running cranes may be more appropriate for applications with low headroom.
Columns
Sometimes, overhead bridge cranes will be built onto a building’s ceiling structure. These systems, known as ceiling-mounted cranes, don’t need support columns. If your building can’t support the weight of an overhead crane, you’ll have to install columns to provide enough support for the crane’s parts and components, as well as the intended loads.
The height of your system’s columns will depend on your lift height requirements and the facility’s vertical space. Additionally, the number of columns you need will depend on the size of the overhead crane system you need. A small bridge crane may need only four columns, but you can increase the coverage indefinitely by adding more columns.
End Trucks
A bridge’s end trucks ensure it can glide up and down the runway. One bridge will have one end truck on each end. These trucks attach directly on top or bottom of the runway and may incorporate drive wheels to help it move back and forth. Higher-capacity overhead bridge cranes may have larger end trucks or use multiple end trucks to distribute the greater weight.
Electric Connection
A crane’s electrical parts supply the power. Some bridge cranes, especially high-capacity systems, may require electrical power for the bridge, hoists, and trolleys.
An overhead bridge crane with electrical power will feature insulated conductor bars, a series of cables called festooning, and power boxes to supply power. In most cases, the electrical system will power several crane components
Controls
There are a handful of ways to control an overhead bridge crane. An electric-powered overhead crane will use an attached pendant controller, a wireless battery-powered remote, or a mounted control system. Typically, using a wireless remote will be the safest option, as crane operators can operate the crane from a distance. As a result, they won’t be in the system’s way during operation and will have a better view of where loads are traveling.
Bumpers
An overhead crane system can include bumpers to reduce stopping impact. During installation, you can place bumpers at almost any point you want to limit bridge movement. For example, placing bumpers at the ends of each runway rail will ensure the bridge comes to a softer stop. If your system includes multiple bridges, you can use bumpers to keep them separated.
Keep in mind that you’ll need to replace bumpers as they wear down to prolong your overhead bridge crane’s life.
Wheels
Numerous types of wheels help an overhead crane operate correctly. As we’ve mentioned, the bridge end trucks feature wheels that ensure they can move smoothly across the runways. Additionally, the trolley uses wheels to run back and forth across the bridge. This is a crucial part of the overhead bridge crane system, so you must ensure your wheels are always in working order.
Types of Crane Wheels
According to different standards, crane wheels can be classified into different types, such as, single edge and double edge crane wheels, casting and forging crane wheels, etc. In the following, single edge and double edge crane wheels will be introduced in length.

410 Stainless Steel
This martensitic alloy is used in special forgings for its ability to be hardened to some degree and its ability to prevent moderate corrosion and wear.
17-4 Stainless Steel
This martensitic alloy is used in special forgings for higher corrosion resistance. Since age hardening is conducted at low temperatures, parts can be finished machined and age hardened without much distortion.
300 Series Stainless Steel
This austenitic alloy is used in applications where the highest level of corrosion resistance is required. The material is solution treated followed by quenching to provide a high impact, low hardness material with excellent corrosion resistance.
overhead crane wheel heat treatment
Overhead crane wheels are a small but important part of an overhead crane. The quality of the overhead crane wheels affects the overhead crane quality and operation. The heat treatment to the crane wheels can directly the quality of overhead crane wheels.

Materials of overhead crane wheels
Overhead crane wheels usually are produced from the ZG310-570 cast steel or steel with better quality. The small-size overhead crane wheels can be made of forged steel but not below the 45th stainless steel. The bear crane wheels bearing heavy loads are made of alloy steel, such as ZG55CrMn, ZG50MnMo, etc. Alloy materials are also used when it is required to reduce the diameter of the overhead crane wheels and eventually to lower the height of the overhead cranes.
Heat treatment of overhead crane wheels
In order to increase the load capacity and service life of the crane wheel, the wheel tread must be heat treated. It is required that the medial surface of wheel hardness is 300-380HB, 20mm of hardened depth not less than 260HB, which can be achieved under the current technical conditions by using a variety of heat treatments.

How to Choose Overhead Crane Parts?
Overhead cranes are essential equipment for many industries, such as construction, manufacturing, mining, and more. They can lift and move heavy loads with ease and efficiency. However, to ensure the safety and performance of your overhead crane, you need to choose the right parts for it. Here are some tips on how to choose overhead crane parts.
Know Your Crane Model and Specifications
Different cranes have different requirements for their parts, such as size, capacity, speed, and power. You should check the manual or the label of your crane to find out its model and specifications. This will help you narrow down your options and avoid buying incompatible parts.
Choose Quality Parts from Reputable Suppliers
Overhead crane parts are subject to wear and tear, so you need to choose parts that are durable and reliable. You should also buy from suppliers that have a good reputation and offer warranties and after-sales services. You can check online reviews, ratings, and testimonials to find out more about the quality and reputation of the suppliers.
Consider the Maintenance and Repair Costs
Overhead crane parts are not cheap, so you need to consider the long-term costs of maintaining and repairing them. You should choose parts that are easy to install, operate, and maintain. You should also avoid parts that are obsolete or hard to find, as they may increase your downtime and expenses.
Compare Prices and Features
Before you buy any overhead crane parts, you should compare the prices and features of different suppliers and brands.
