Installation with support means for driving a liftcage, and corresponding support means

摘要

The elevator system (10) has a suspension arrangement (13.1,13.2) and a driving pulley (16) for driving the suspension arrangement, whereby the suspension arrangement at least partly passes round the pulley. The suspension arrangement has a safety section (17) that causes the suspension arrangement to pass through by an interaction between the drive pulley and the safety section. Independent claims are also included for the following: (A) a supporting arrangement for an elevator system (B) and a method of providing overdrive protection.
