The uses of an overhead gantry crane are numerous and diverse. These include lifting and lowering of vehicles, machinery, and other loads. They are also used in many applications, such as warehousing, reeving, and shipping containers. Overhead gantry crane types may include portable, telescopic, asymmetric, and helical gear drive.
Shipping
When you think of an overhead gantry crane, you probably think of loading and unloading shipping containers. In fact, these cranes are used by many industries, including shipyards, warehouses, and construction sites. Gantry cranes are designed to provide a safe, efficient means of moving heavy items. They are also easy to use.
A gantry crane is an ideal type of crane for the shipping industry. These cranes are available in a variety of sizes, styles, and designs.
Warehousing
If you are planning to install an overhead crane in your warehouse, you will have to determine the right size for your needs. For instance, you will have to consider the travel path, lifting capacity, and the nature of your business.
There are several different types of overhead cranes that you can choose from. These include the single girder and double girder design. They can be used in both indoor and outdoor working environments.
Reeving
In order to properly operate an overhead gantry crane, it’s important to understand how to reeve the hook block. This will impact the capacity, lift speed, lateral movement, headroom, and overhead space.
When you reeve a hook block, you must be sure that you use the correct cable. The wire rope must be routed correctly so that it doesn’t get twisted. You also need to attach the end of the cable to the man lift.
Helical Or Bevel Gear
In an overhead gantry crane application, a helical or bevel gear drive can be useful. It provides flexibility and ease of maintenance and replacement. However, it is not the best choice for a travel drive on a dockside crane or in a gantry crane that needs to move loads at a slow pace.
There are many advantages to be had from a helical or bevel gear, but you must choose a gear that is appropriate for your application. For instance, helical gears have more teeth that are in contact with each other, which reduces friction and increases efficiency.
Portable Gantry Cranes
Portable gantry cranes are a great way to move heavy objects. They are easy to set up and are portable, meaning you can move them from location to location as needed. Whether you’re a contractor, warehouse, or factory, a portable gantry crane can be a great solution.
Portable gantry cranes are available in various sizes, with a lifting capacity of between one to five tons. Unlike larger gantry cranes, these portable units are light and less costly.
