The Buffer OH-J11 works as a shock absorber at the bottom of the elevator shaft. When the lift car reaches the lowest floor, this elevator buffer OH-J11 absorbs the impact energy and brings the car to a safe, controlled stop. It plays a key role in lift safety by protecting passengers, cables and the machine room from damage during hard landings. This elevator shock absorber is a must-have part for any elevator maintenance or repair job in residential or commercial buildings.
