Elevator Pit Tension Device THY-OX-300

THY-OX-300 heavy hammer type tensioning device is connected with a safety gear and a speed limiter by a steel wire rope. This contact is normally closed. When the elevator traction wire rope breaks, the safety circuit will be disconnected. Installed on the guide rail side of the elevator pit, the tension block is divided into high-density ore and cast iron. The appropriate tensioner size and counterweight material are selected according to the elevator lifting height. If the lifting height exceeds 50 meters, the counterweight needs to be increased. the weight of. Use gravity to tighten the wire rope of the speed limiter-safety gear protection device to ensure the drag force of the speed limiter on the wire rope. The wire rope of the tensioner is connected to the safety gear link arm. The safety gear link arm is mounted on the car and moves with the car. When the car moves up and down, the wire rope of the tensioner will move together. When the car overspeeds, the overspeed governor will act, disconnect the safety circuit, pull the wire rope, and pull the connecting rod arm of the safety gear to make the safety gear move and jam the car on the guide rail. The diameter of the steel wire rope can be selected from φ6 and φ8, and the tension pulley can be selected from Φ200 and Φ240 mm. The matching speed limiter is suitable for ordinary indoor working environment.
