Components of the gantry crane operating system 

Gantry cranes are overhead cranes and can have double or single girders. The crane is supported by freestanding vertical pillars which move on a rail track. 

The components of the crane include the riving engine with breaks. There is a rail track or wheels for the freestanding legs to move. The vertical pillars not just offer support but also complete the entire system in such a way that the crane stands firmly. 

So, the main components include the drive unit which handles the load, the support unit that offers support to the drive unit and makes the movement possible, the track on which the train runs, and the device.

Working principle of the gantry crane 

A coupling and a reducer connect the motor of the crane for it to start. The reducer has a shaft which starts rotating at low speed to bring the wire rope and the hook together. As soon as the motor starts, the movements get transferred to the reel which makes it move in clockwise and anticlockwise directions. With the movement, the wire rope gets rolled in and out, making it possible to lift or lower the load. 

The working of the gantry crane depends on the transformation of movement initiated by the monster into lifting and lowering of the load. If there is any sudden power cut, the operator applies breaks and the load stops at a specified position. Also, when the load reaches its limit position, the hook’s movement is automatically stopped as the limiter is touched. 

Usage of gantry cranes 

Gantry cranes are of many types and all of them serve different purposes. Depending on the available space, load requirements and other factors, different types of gantry cranes are used in different work spaces. Here are some of the types of gantry cranes:

The industries such as shipping and container yards, rail yards, scrap yards, steel yards, etc. The cranes are designed to work well in outdoor applications. These are large cranes and the trucks and other traffic can pass underneath them making it possible to work outside without worrying about space blockage. 

Portable gantry cranes are also quite useful. These offer greater flexibility than jib cranes and can function well as a workstation crane.
