Abstract
An elevator device which can have a buffer equipped without setting a special installation mechanism has obvious effects in shortening the depth and size of a pit. The elevator device comprises an elevator car (4) elevating inside an elevation channel (1) and comprising a buffer (5) and an emergence brake device (6). The buffer comprises a cylinder body and a piston inserted inside the cylinder body. When a fault occurs in the elevator car and an elevation position runs beyond a set position, the buffer is then applied for buffering the collision received by the elevator car. The emergence brake device which is equipped on the outer side of the elevator car comprises a brake member capable of performing sliding contact with a guide rail vertically equipped inside the elevation channel and is applied for braking the elevator car when a fault occurs. The buffer is equipped on the emergency brake device. Meanwhile, the buffer is equipped in a way to be projecting from the lower end of the elevator car. The projecting size of the buffer is equal to a required size gap between the elevator car and a pit floorboard (7a) when the buffer runs for a cushioning stroke and then stops.
