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
RDU-5 5 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.

Drive Options

  • Air drives
  • NEMA 12 and 4 control enclosures for (indoor use)
  • Explosion proof enclosures and wiring
  • Special protective coatings

Standards

General Design Standards:
Spanco cranes are designed in conformance with the following applicable standards:

  • Workstation Bridge Cranes: AISC Steel Construction Manual, OSHA 1910.179, ANSI B30.11, AWS D1.1/D1.6, and MMA MH27.2
  • Gantry Cranes: AISC Steel Construction Manual, OSHA 1910.179, ANSI B30.11, AWS D1.1/D1.2/D1.6, and CMAA 74
  • Jib Cranes: AISC Steel Construction Manual, OSHA 1910.179, ANSI B30.11, AWS D1.1/D1.6, and CMAA 74

All Spanco cranes have a design factor of 15% of the allowable capacity for the weight of the hoist and 25% for impact.

Fabrication Standards:
All welding performed during the manufacturing of Spanco cranes meets the American Welding Society’s (AWS) D1.1/D1.2/D1.6 Standards.

Spanco, Inc. is officially certified as an AWS Certified Welding Fabricator (CWF). This means that not only are all welders AWS Certified, but all processes and procedures adhere to AWS CWF requirements. Examples of requirements include annual calibration of all welding machines and Level 2 visual inspections on all load-bearing components.

Material Standards:
All steel used in the manufacturing of Spanco cranes meets the following applicable ASTM International specifications:

Structural Steel Shapes: ASTM A-36
Structural Steel Pipes: ASTM A-53
Structural Steel Tubing: ASTM A-500

Steel plate and round bar used in Spanco cranes have minimum yield strengths of 36 KSI.

Surface Preparation & Painting Procedures:
Spanco adheres to the standards of the Society for Protective Coatings (SSPC) for all product surface preparation. Prior to painting, all Spanco crane components are deburred and descaled using power tools equipped with sanding discs and wire wheels. Components are then washed utilizing a high-pressure/high temperature biodegradable degreaser solution. Parts are wiped clean and allowed to dry before the painting process. During painting, all components surfaces are coated with a quick drying, semi-gloss enamel, applied to a minimum dry-film thickness of 2 to 3 mils. A finishing coat is applied with a hot, airless, electrostatic spray paint system. Painted components are cured at air temperature.

Deflection Guidelines:
The following guidelines for deflection and stress are followed by Spanco engineers during the crane design process:

  • Workstation Bridge Cranes: All models designed to L/450
  • Jib Cranes: Wall-Mounted Cantilever (300 Series) models designed to L/150, Freestanding (100, 101, and 102 Series), Mast Style (200 Series), and Wall-Mounted Bracket (301 Series) models design to L/450
  • Workstation Jib Cranes: Wall-Mounted (WC Series) models designed to L/225, Freestanding (FR Series) models designed to L/150
  • Gantry Cranes: All steel series models to L/600, Aluminum models to L/450

Quality Standards:
Spanco, Inc. is an ISO 9001-2008 Registered corporation. This means that Spanco cranes are manufactured to standards ensuring safety, reliability, and the highest quality. Spanco, Inc.’s ISO designation also allows for continuous improvement based on customer feedback.
