  • a lift to be installed has a cabin of 220cm inside height. Approximately 10cm are needed for crossing above the cabin. For the lift door drive, it also requires certain height. This leaves only 50cm left in the top normal lift position. These are called Safety buffer needed. If the lift stops at the top floor with a heavy load, exactly at floor level, and then is relieved of load, the cabin can still lift by a few cm due to the elasticity of the suspension ropes. Even then there must still be a gap wide air up to the lift shaft head, so that in no case can strike the elevator car at the same.

Abstract

La cabine d'ascenseur et le contre-poids (30) sont guidés chacun sur une paire de rails de guidage verticaux placés le long d'un mur de la cage. Au moins deux câbles (41, 42) sont guidés dans leur partie supérieure autour d'un cylindre de traction (26) monté sur un pont de montage fixé aux rails de guidage. L'axe de rotation du cylindre de traction est parallèle au mur adjacent de la cage. Les câbles (41) conduisant vers le bas et situés sur la paroi de la cage portent le contre-poids (30) du fait qu'une moitié des câbles (41) comporte dans sa partie inférieure l'une de deux poulies de renvoi (29) servant de poulies libres et que l'autre moitié des câbles (41) comporte dans sa partie inférieure l'autre des deux poulies de renvoi (29). Les axes (11) de ces poulies de renvoi (29) sont horizontaux, adjacents et parallèles l'un à l'autre et portent le contre-poids (30). En outre, ils sont perpendiculaires à l'axe du cylindre d'entraînement (26). Les câbles (41) situés de l'autre côté de ces poulies de renvoi (29) conduisent vers le haut jusqu'au pont de montage et y sont fixés. Les deux autres câbles (42) au moins partant depuis le cylindre de traction (26) vers le bas portent la cabine d'ascenseur. Une moitié de ces câbles (42) porte l'une des deux poulies de renvoi (28) et l'autre moitié porte l'autre poulie de renvoi (28).
