Retractable protective equipment with rescue lifting

The retraction type safety device with rescue lifting device (class B) "NV evak" is a safety device with automatic tensioning and return of the retraction sling with self-locking and kinetic energy dissipation function, including the function of the rescue lifting device class B. Depending on the mode used, either the rope is pulled out of the device and automatically reeled back in, or the worker is lifted / lowered. If the pulling speed exceeds 2 m/s, the rope is locked, preventing the user from falling. The force exerted on the person at the moment of stopping the fall does not exceed 6 kN due to the internal shock-absorbing mechanism. The carabiner, designed to be attached to the safety point on the tether, has a swivel as well as a breakaway indicator.
