The Retrofit Jib Drives feature a modular design that bolts onto the back of any box style head assembly. Our jib drive features a high-efficiency electric motor and ultra-reliable worm gear reducer. The worm gear drives a set of large steel rollers fitted with polyurethane treads for exceptional durability and traction on the crane’s mast. The rollers are constantly kept at the correct pressure against the mast via a spring-loaded tension adjustment mechanism, assuring smooth operation.
Jib Drive Control Panel: Includes mainline contactor, reversing magnetic contactors, thermal overload, 110V fused control transformer, branch circuit fusing to crane motor, and solid state “soft start” control adjustable for time and torque—all in a NEMA 3R enclosure.
