KBK jib cranes
have a single enclosed-track boom that pivots about a central column. Normally they are floor-mounted, but they can also be attached to a wall or to the side of a machine.
An articulated jib has a joint midway along the boom, to be able to reach around an obstruction, or to be able to collapse to pass by an obstruction.
Rating: Least expensive crane style, not recommended for fast-paced, repetitive
