There are both subtypes of overhead cranes: gantry and jib cranes.Ī variant of this overhead crane is the gantry crane, although sometimes both terms are used interchangeably. Its name comes from the fact that it resembles a bridge supported by both steel beams, which straddle the workload, together with the hoist travelling along the bridge part of the crane.

The bridge crane also called an overhead crane, is generally found in industrial environments. The tracks are usually mounted across the side of an assembly area. They move at angles to the direction across the ground or elevated level tracks. The hoist of the crane is set onto a trolley that can move in one direction along a beam, sometimes both beams. The telescopic crane consists of a large boom where some numbers of tubes have been fitted inside with each other. The cranes are basically for heavy construction work and for all types of lifting tasks.Įquipped with pulleys and cables and based on the use of fundamental mechanical principles, a crane could lift and lower loads that no human working capacity could.Ĭrane design has evolved to meet the requirements of a wide variety of industrial needs, and modern cranes often coordinate simple systems to do complex lifting jobs – sometimes in environments that could be dangerous for human workers.Īlso, Read: Different Types of Plumbing Pipes for Different Use 18 Types of Cranesĭifferent types of cranes are as follows. How does a crane work?Ĭranes are part of the construction process since its invention in Greece. The mechanical benefits created by several elements on the crane may produce powerful strength. Equipped with a hoist rope, cable ropes and sheaves, it may be used to lift heavy loads or transport them to other places. A crane is a significant type of construction machine that’s utilized to move the loads horizontally.
