Retractable devices connect the operator to the fall arrest system, allowing wider movement with respect to the lanyards.
Because of the greater cable length, it is very important to assess the type of operations performed when choosing the most suitable type of retractive and its length.
The retractable devices sold by Genesi Italia comply with different regulations that certify their different uses:
EN 360. Retractable devices against falls from heights
EN 341. Self-rescue devices: in the event of a fall, the product locks the operator and then accompanies him to the ground at a controlled speed. Before choosing a retractable device with these characteristics, you must verify that the space underneath the work area is free of any obstacles and that the rope is long enough to allow the operator to reach the ground.
EN 1496. Retractable devices with safety crank: in the event of a fall, the other operator can rescue the injured person using the safety crank, lowering him down or recovering him from above.
Products are available with steel ropes (stainless or galvanized steel) or with polyamide automatic recall belts to keep the cable taut.
In the event of a fall or if the maximum speed of work is exceeded (about 1.5 m/s), the centrifugal force sets the device into action, locking the cable. The necessary energy for it to stop is supplied by a built-in friction system.
