Enclosed Track Tractor Drive

Spanco Enclosed Track Tractor Drives can be installed on workstation bridge cranes and monorail cranes to motorize trolley travel, bridge travel, or both bridge and trolley travel. The new and improved design features a number of upgrades, including a direct drive shaft, naturally weight balanced without the need for counterweights, and improved headroom.

The use of a tractor drive is ideal for applications where it is difficult or impossible to move. These applications can include heavy or awkward loads, systems that operate over long distancing or at high cycle times, or situations where workers cannot physically reach the load to move it manually. A Spanco Tractor Drive can improve material handling processes for many applications where manual operation just doesn’t work.

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), Wall-Mounted Cantilever (300 Series), Articulating (400, 401, and 402 Series), and Foundationless models (600 and 605 Series) 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 9001:2015 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.
