industrial cable assemblies

Cable and pulley diameters are important to consider when putting together cable assemblies.

With decades of experience in industrial cable assemblies, Bergen Cable is the name to trust for advice on putting together the strongest cable system. The company offers valuable tips and resources on its website, from basic cable information to tips on wire rope and specifications.

On the topic of putting together cable systems, Bergen Cable highlights four considerations: assembly tolerances, conduit-length tolerances, breaking-strength safety factors, and how the cable diameter relates to the pulley or sheave diameter.

An effect on costs

Frequently, production methods are dictated by the overall length tolerances required for industrial cable assemblies and by the cable’s cut lengths – and this has a direct effect on costs. Close assembly tolerances often cost more as far as production and quality assurance. This is why Bergen Cable should review and approve allowable tolerance and inspection methods before production begins.

The user should consider the distance between designated measuring points as shown in the different sections when specifying assembly lengths. These measuring points are typically located at the fittings’ load-bearing points. For an assembly length of 100 feet or more, commercial tolerance should equal plus or minus two per cent of the length, while special tolerance should equal plus or minus one per cent of the length; these tolerance figures decrease as the lengths do.

Bergen Cable should also review acceptable conduit-length tolerances and inspection methods in advance of production. Overall tolerance should be plus or minus ¼ of an inch for conduit lengths that exceed two feet, 1/8 of an inch for conduit lengths between one and two feet, or 0.062 of an inch for lengths under one foot.

Users must consider direct stress and the shock in bending loads when determining the working load of cable, then apply a reasonable breaking-strength safety factor to the load. In many applications, the standard safety factor is five to one. Finally, properly designed pulleys can enhance cable fatigue life, so it is important to identify the minimum ratios of the tread and cable diameters.

Follow these steps for the most reliable industrial cable assemblies.
