Title: POWER TRANSMITTING SYSTEM THROUGH ROPES
Abstract:
A power transmitting system (P) is described, comprising at least three first pulleys (1, 5, 9') having a first diameter, having a first rotation axis mutually identical and adapted to operatively cooperate with at least two second pulleys (3, 7'), having a second diameter and having a second rotation axis mutually identical and different from the first rotation axis, the first diameter being greater than the second diameter, and a rope (2) adapted to pass in succession around the pulleys (1, 3, 5, 7', 9') in order to follow a path adapted to provide an extended friction surface for the rope (2).
