圧エレベータの安全装置。 A buffer is provided in the pit of the hoistway opposite the car, a hoisting rope is connected to the car, pressure oil generated by a hydraulic unit is sent to a cylinder, and a plunger is raised and lowered to drive the hoisting rope. When the hoisting rope is loosened, an emergency stop device is activated to stop the car, and an emergency stop switch stops the operation of the elevator. a bottom floor stop detection means for detecting that the car has stopped; a power supply detection means for detecting cutoff of the power supply voltage of the hydraulic unit; and a car for detecting that the plunger is lowered and the car comes into contact with the shock absorber. When the descent detection means, the lowest floor stop detection means, the power supply detection means, and the car descent detection means are activated, the emergency stop switch is short-circuited, and the hydraulic elevator can be started after the power supply voltage is restored. 1. A safety device for a hydraulic elevator, characterized in that it has a release means.
