A jib crane is a type of crane that consists of a horizontal boom, known as a jib, which is attached to a vertical mast or support structure. The jib can rotate horizontally, allowing the crane to have a wide range of motion. The crane typically has a hoist or lifting mechanism at the end of the jib, which is used to lift and move loads.
