Turnbuckle Jib Cranes
Knight’s MJBA2100 & MJBA2200 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 10 ft. [3m].
