Overall Structure:
A jib crane is characterized by a horizontal beam, known as a jib or boom, that extends outward from a vertical support.
This jib can rotate, allowing the crane to cover a circular or semi-circular work area.
The lifting mechanism, or hoist, travels along the jib. Components: Jib (or Boom) :
This is the horizontal beam that extends outward.
It can rotate, providing the crane's circular or semi-circular coverage.
The length of the jib determines the crane's reach. Vertical Support (or Mast) :
This is the vertical column that supports the jib.
It can be floor-mounted, wall-mounted, or pillar-mounted.
It provides the rotational support for the jib. Trolley :
this is the unit that moves along the jib, and carries the hoist. Hoist :
This is the lifting mechanism that raises and lowers the load.
It travels along the jib.
It can use wire ropes, chains, or other lifting devices.
