The puller cable, which is mounted on a loop, is drawn by a drive pulley located between two deviation pulleys; one guiding the puller strand towards the “lower shoe”, from which the load-bearing cables begin and the other towards the “upper shoe”, from which the support cables for the return puller cable originate.
This drive pulley is usually drawn, through its reducers, by two electric motors, each of 530Kw power, impelling the puller cable with a speed of 12.5m/s. An “electric” generating set, with 225 KVA power, can supply current to the standby motors if necessary.

A recovery drive pulley is attached to the main drive pulley. It is coupled by a sprocket wheel and crown gear to an “electric” reducer. The speed of recovery is 0.5m/s.
