The lift installation comprises a cabin (10) and counterweights (12) installed in a shaft along guide rails. A motor (40) rotates a traction pulley (38) and the cabin and counterweights are suspended by a cable (14). A linear element (30) which drives the cabin-counterweight system is wound around the traction pulley with a rubbing contact.
