Cable lifting pulley LEG series

The series of Greifenberg’s pulleys is made in full compliance with existing regulations, by paying special attention to restrictions concerning the throat bottom rounding radius and the diameter around which the cable is deviated, so not to ruin the cables by pinching off or yielding them. The frame, pulley and bearings have a safety factor equal to 5, in order to provide an effective resistance to stress peaks, as well as to expected load, thus guaranteeing the maximum operation safety
