Abstract:
An elevator car includes a foldable handrail mounted on top of the car. Safety switches are associated with the foldable handrail including a first safety switch and a second safety switch. The first safety switch is closed only when the handrail is folded in a fully retracted position. The second safety switch is closed when the handrail is unfolded in a fully deployed position. A safety chain is associated with the first and second safety switches for supplying power to an elevator drive system in a normal operation or an inspection operation depending on the state of the first and second safety switches.
