Minimum Braking Load given in [kN] Tensile strength – nominal durability given in [N/mm2]

Weight

During use, a rope undergoes tension set, which equals approximately 0,2–0,5%, and for ropes which are heavily used it might even be 0,8%.

The extent of tension set depends on the load, metallic cross section, and construction complexity, which is determined by elasticity module (E). There are values of this module for selected rope construction. The tension set is not permanent and disappears when the load is taken off. Elasticity module (E) is approx. 25% higher for ropes with steel core.

Construction E [kN/mm²] 1x7 150 1x19 140 6x7 95 6x19 90 6x37 80 Non rotating 115

	Unit elongation (%) can be calculated from the formula below. Using the minimal breaking load value (MBL) in the formula gives a maximal value of elastic elongation for a new rope.
	A - Metallic cross-section [mm²]
	Ropes with a low elasticity module are better with dynamic loads, and ropes (and strands) with a higher elasticity module are better with transporting static loads.
