Can Anybody tell the safety features in all elevators / lift?
Most elevators which travel six or more floors are “traction” design. Traction elevators are suspended by strong steel cables propelled by a hoisting machine. Counterweights help balance the load and make it easier for the machine to move the elevator. The steel cables are very strong, and can safely hold several times the weight of the elevator and its full load of passengers. The safety brake, together with a speed-sensing governor, acts to stop an elevator if it should overspeed in the down direction. If an elevator overspeeds, the governor makes the safety grasp the rails on which the car travels, bringing the elevator to a safe emergency stop. The door system on a modern elevator also includes several safety devices. Sensors detect passengers or objects in the door opening, preventing the continued closing of the doors. Older systems use mechanical “safety edges” which cause the doors to stop or retract when they make contact with a person or object. More modern systems use a larg
