Abstract
An elevator car includes a cross-head portion and a balustrade mounted to the cross-head portion. The balustrade is moveable from a retracted position for normal operation of the car to a deployed position for inspection operation of the car. The car further includes a second retractable safety device also mounted to the cross-head for preventing or limiting movement of the car. The balustrade includes at least one control for operating the elevator car during the inspection operation, the control being arranged so that the control cannot be operated when the balustrade is in the retracted position.
