Power Drive Kit
Overview

Spanco Power Drive Kits for our PF-Series Gantry Cranes allow high-volume high-capacity gantry travel along V-groove tracks, guide angles, crane rail, or truly trackless paths.

The power drive kit includes: Two drives with drive wheels and sprockets; chains; two gear reducers; two single-speed, 230/460V, three-phase, TEFC motors; solid state, adjustable “soft start”; and two idler assemblies. Standard travel speed is 50 FPM.

  • V-Groove Track Drives: Two motors drive rigid steel V-groove wheels along a fixed path
  • Guide Angle Drives: Ideal for installations where the gantry runs along a wall, two motors drive polyurethane wheels that are guided on one side by a guide angle (locally sourced). The guide angle lags into the floor, typically at the base of a wall. The kit includes guide rollers on one drive and one idler assembly. Both drives and idlers come with polyurethane bumpers.
  • Truly Trackless (Aligning) Drives: Ideal when you need to keep your shop floor clear of any tracks or angle guides, a selector switch on the control pendant selectively turns each motor on and off to guide the gantry along

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 following American Welding Society’s (AWS) standards: D1.2 for aluminum and D1.1 for steel.

Spanco is officially certified as an AWS Certified Welding Fabricator (CWF). This certification 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 aluminum used in the manufacturing of Spanco cranes meet ASTM International specification ASTM B308 for 6061-T6 aluminum.

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 Grade B
Structural Square and Rectangular Steel Tubing: ASTM A-500 Grade B

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 are designed to approximately L/450
  • Jib Cranes: Freestanding (100, 101, and 102 Series), Mast Style (200 and 201 Series), and Wall-Mounted Cantilever (300 Series) models are designed to approximately L/150; Wall-Mounted Bracket (301 Series) models are designed to approximately L/600 at midspan
  • Workstation Jib Cranes: Wall-Mounted (WC Series) models are designed to approximately L/225; Freestanding (FR Series) models are designed to approximately L/150
  • Gantry Cranes: All steel series models are designed to approximately L/600; Aluminum models are designed to approximately L/450

Quality Standards:

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