What Is a Jib Crane?

Cranes are an essential part of most of the civil engineering project. Various types of cranes are used depending on the weight to be lifted and the area available for movement. One type of crane is a crane jib. You can get to know more info regarding all terrain crane via searching online.

A jib crane is a type of crane that utilizes sleeve mounted in the lifting, moving and lowering material. The arm, which is fixed on perpendicular to the wall or pillar, can rotate along a central axis to a full circle or arc is limited. These cranes are typically used in industrial sectors, such as docks and warehouses, on loading and unloading shipping containers.

Jib cranes history back to ancient Greece when the idea of lifting with mechanical arms that are commonly used. On a similar note, the Romans later adopted the concept and use it in the construction of waterways, roads, and other engineering structures. Crane sophisticated, yet identical in design to the classic until the invention of the steam engine and the industrial revolution in the nineteenth century.

The working principle of the jib crane

The basic idea comes from the concept of crane mechanical advantage. Mechanical advantage refers to the principle that a machine, such as a pulley, capable of multiplying the force applied to it by a certain factor.

This explains why it is possible, for example, for one person to use a pulley to lift heavy things that will require the combined strength of many men to lift the same load directly. A crane combines various pulleys with simple machines, like levers and gears, to significantly increase the lift capacity.
