Turnbuckle Jib Cranes

Knight’s Turnbuckle Jib Cranes are ergonomically designed to accommodate workstations where ceiling heights are inconvenient for an overhead crane system. This series offers a large tool coverage area with a single rotating rail on a floor-mounted pedestal. It also has a level adjustment screw used to adjust the pitch of the rail and an adjustable hard stop.

Knight Jib Cranes have Timken® Tapered Roller bearings that provide a smooth 360 degree rotation and have boom lengths available up to 20 ft. [6.1m].
