WIRE ROPE CABLE / WIRE ROPE ASSEMBLIES CONSIDERATIONS

When selecting the appropriate wire rope cable for your wire rope assemblies or control product, there are a few factors which need to be considered?

CONSTRUCTIONAL STRETCH: All wire rope cables have spaces between each strand and wire. When a load is applied, the spaces between the wires are reduced and the wire rope cable will grow in length. The amount of the growth is determined by the load applied, length of the cable and construction of the cable. MCT assemblies can be proof loaded (by applying a load of 60% of min. cable breaking strength to the assembly) to eliminate any constructional stretch.

ELASTIC STRETCH: An elongation of the cable wires when a load is applied. This can be a significant factor when the yield point of the wire is surpassed. Please contact Motion Control Technologies to determine the elastic stretch of a specific cable.

MINIMAL BREAKING STRENGTH: The minimum breaking strength is referred to as the minimum tensile strength. This is measured in lbs. or kgs. and should be based on the max working load and safety factor. The recommended minimum safety factor ration is 10:1 which represents (min. breaking strength TO max working load)

Other factors to determine when designing the correct cable for your requirements are CABLE DIAMETER, CABLE MATERIAL, and COATING ON THE CABLE
