• Tension pulley with diameter 300mm. • The return pulley is attached to the lift guide. • Overspeed governors to act in ascent and descent or only descent. • The pulley can be polyamide (FV) or foundry (FG25).
Tension pulley that applies the necessary tension on the overspeed governor cable to put the safety action.
The return pulley is attached to the lift guide by means of a plate and three flanges, the pulley and the counterweight being suspended from this plate. The electric safety device is also attached to the plate at the bottom, and this will be activated in the event of the overspeed governor cable breaking or loosening. The fastening plate has a number of slots to allow the necessary distance between the cable and the guide axis to be regulated, and also to fasten it to guides of various widths.
All tension pulleys have rope out protection and protection against stray objects regardless of being for overspeed governors with tripping in descent or bi-directional.
