Thanks to controlled rope slipping, KISA (Kong Impact Shock Absorber) is suitable to create shock absorbing systems. It can be used in two configurations, via two set of holes suitable for different diameters of rope (around 9mm or 11mm), allowing various degrees of friction.
The user can self-make its own system that can be created choosing the most appropriate way for the situation on-point, by taking into account types of rope and connections, number of forces involved, weights, environmental conditions (wet, dust, snow… make the rope stiffer and not so sliding), wear, and what could happen during use. When correctly evaluated, those parameters allow to obtain a system fine-tuned according his requirements. Remember that the free rope end must not slip out from the KISA, while giving enough length to absorb the greatest foreseen shock!
Because it is not possible to test all configurations and uses, this device is not a PPE and it has not been tested according to EN958.
