Product Description
Retrofit Jib Drives
Overview
The Spanco Retrofit Jib Drive converts your existing manual rotation jib crane to motorized rotation for a fraction of the cost of a new powered crane.
Our jib crane conversion kits are ideal for powering the rotation of heavier loads or when your production situation makes manually rotating the jib unsafe, impractical, or unproductive.
| Model | Capacity | Jib Span | Speed, Nominal |
|---|---|---|---|
| RDU-2 | 2 Ton | 20′ | 1/2 RPM |
| RDU-3 | 3 Ton | 20′ | 1/2 RPM |

UNIVERSAL RETROFIT DRIVE FITS ANY FREESTANDING JIB CRANE WITH A BOX STYLE HEAD
Spanco 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.
The Spanco Retrofit Jib Drive is recommended for indoor applications only.
