Abstract
PURPOSE: To reduce the stopping shock of an elevator cage in double ways by providing a buffer for enclosing a hydraulic cylinder and an elastic member making contact with the floor of the cage at the top of a plunger.
CONSTITUTION: The plunger 5 of a hydraulic cylinder 7 is coupled through a vibration-proof rubber 3 with the bottom of the floor 2 of an elevator cage 1. Steel plates 11a, 11b are adhered onto vibration proof rubber 3. When the cage 1 collides with a buffer 8, a stopper 12 provided at the plate 11b prevents abnormal deflection of the rubber 3. When the cylinder 7 is abnormally lowered to cause the plate 11b to collide with the buffer 8, its pressure is received by the bottom surface 10. Thus, the stopping shock of the cage is reduced by the rubber 3 and the buffer 8 in two ways.
