Basic Parts of a Crane: Understanding their Main Functions

November 6, 2020

Construction and transport industries have been utilising different types of cranes for a long time now. These machines are known for their ability to lift, move, and lower materials from one area to another. They can likewise transport heaving equipment and things to a place where they are intended to go to.

Some cranes have crawlers or rubber-tired carriers that can be driven into and around a site. Others, alternatively, are intended to be set up and installed in one stable place so they can work on their lifting functions easily. Despite these key differences, however, most of these cranes boast components that carry out their load moving and lifting operations. These components are the primary reason why cranes, whatever their type is, work and function optimally and efficiently.

To better understand how cranes normally work, here are some of their basic parts and their corresponding functions and purposes.

Hoist and Hook

Both the hoist and the hook work together in performing the lifting operations. The hoist, which is normally located at the base of the boom, is responsible for the holding, raising, and lowering functions of the crane. It runs a cable to the top of the crane that then holds the hook. The hook is subsequently attached to the end effector, which is a component that carries out the grabbing action of the crane system.

End Effectors

And speaking of end effectors, these components are known to be the grabbing part of most cranes. They may come in a form of cables or straps. However, the most effective end effectors are the ones that are customised, which can specifically fit in with the type of load intended to be lifted. Having your end effectors customised can make the whole lifting operations safer, faster, and more accurate.

Crane’s Boom

The boom of the crane is characterised as the long arm that is connected to the hoist and hook. This component is intended to lift and move the load around the site. Some cranes are equipped with a boom that comes in one solid piece, while others have a boom that folds to extend for a better and longer reach. Other booms are equipped with a jib, which can likewise extend further.

Operator’s Cabin

All the control options for a crane is operated inside the operator’s cabin. This specific part is required to have great visibility over the motion and movement of the crane to avoid lifting issues. Additionally, the cabin is normally integrated with the driver’s cab and a Rotex gear, allowing this specific crane part to swivel left and right and move the boom from side to side during crane operations.


One integral component of a crane is counterweights. Counterweights are utilised to offset a load and maintain the stability of the whole crane. These components are normally situated on the opposite side of the load. Working with counterweights are outriggers, which are then placed along the sides of the cranes so they can distribute weight effectively and more evenly. These components more or less make up the whole framework of almost all types of cranes. If you need help with hiring cranes, just give us a call at Adz Lift Crane Hire.
