How the jib crane is used to move the load?
The jib moves the load from one place to another plus up and down. The cranes work on both hand-powered rotations along with traverse motion. The cranes can also be operated on an electric powered rotation and hand-powered lift. While the former uses push/pull process to accomplish the task, the later use chain.
