Low Profile Jib Cranes

Knight’s Low Profile 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.

The MJBA2050 is typically used in applications that require light duty tools to be suspended.

The MJBA2300 and MJBA2600 Low Profile Jib Cranes have an adjustable hard stop and a level adjustment screw used to adjust the pitch of the rail. They are considered Medium Duty Jib Cranes.

The MJBA2700 Heavy Duty Low Profile Jib Crane is designed to accommodate heavier loads.
