An elevator car defining an interior space for accommodating passengers and/or cargo, comprising a support frame positioned above the interior space, a working platform moveable between a stowed position, above the interior space, and an operational position, within the interior space and at least one extendable suspension arrangement arranged to suspend the working platform from the support frame. The extendable suspension arrangement includes a connection plate, a first arm member connected at a first end to the support frame and slidably connected to a first connection point of the connection plate and a second arm member connected at another first end to the working platform and slidably connected to a second connection point of the connection plate.

Elevator systems and methods of operation include a tension member support positioned within an elevator shaft, a tension member suspended from the tension member support within the elevator shaft, and a slack detection system. The slack detection system includes at least one biasing element housed within the tension member support and operably coupled to the tension member, the at least one biasing element arranged to receive a load from the tension member and a switch arranged to be moved from a first position to a second position in response to movement of the at least one biasing element, wherein when in the second position the switch triggers an emergency stop of an elevator car within the elevator shaft.

Elevator emergency stop systems

Elevator overrun systems having a first body arranged to be fixedly mounted to a portion of an elevator system or elevator shaft, a second body positioned within the first body and moveable from a deployed state to a retracted state relative to the first body, and a limit switch located at a distal end of the second body, the limit switch configured to interact with a component of an elevator system to prevent movement of an elevator car.
