Description / Price
Tension spring made of stainless steel 1.4310, wire thickness 2.5 mm, length 50 mm (spring body approx. 30 mm), maximum permissible stress without plastic deformation including safety factor: approx. 30 kg (0.3 kN). Permissible movement capacity: approx. 18 mm. >>> Price
For special cases, primarily with Easy Kits and when necessary, with insulation. Especially for wire ropes in base areas which are at risk of being overstretched (from bouncing soccer balls or from people leaning on the springs, etc..). The tension spring acts as a strain relief and increases the stretch-ability, protecting wall brackets from high tension loads and thus from bending, deformation, etc.. The tension spring is also used to prevent the wall brackets from being damaged. With strong cable tension there’s the danger of irreversible extension of the steel spring. The number of springs in a climbing system can be reduced by a sensible arrangement and cross-linking of the wire ropes. In most cases, it is possible to connect at least two ropes with each other via deflection and to incorporate the spring in the middle -- thus making it "responsible" for both ropes. Please refer to the general info on cable clips for further support if needed.
The installation into the cable run takes place before tensioning/clamping the ropes-- so, while they are still slack (e.g. as a "spring group"...photo above) with two additional cable clamps, thimbles and end sleeves.
