What is crane explain various type of crane?

A crane is a machine used to move and lift materials. It consists of a boom or beam, cables, pulleys, and hoisting mechanisms, as well as a controlling unit operated by an operator. Cranes are essential components in many construction and manufacturing processes, making them a vital part of the global economy.

There are several types of crane, including overhead cranes, mobile cranes, tower cranes, gantry cranes, jib cranes, and monorail cranes. Overhead cranes, which use a cable, chain, or rope to carry a load and move it either horizontally or vertically, are the most commonly used type of crane. Mobile cranes are similar to overhead cranes, but are mounted on top of a self-propelled vehicle such as a truck, trailer, or railway car. Tower cranes are used for vertical lifts on tall structures such as buildings, bridges, and dams. Gantry cranes are typically used for loading and unloading ships, while jib cranes can be used for any overhead material handling needs. Monorail cranes are used for moving materials along an overhead track or beam.
