An illustrative example elevator system includes a hoistway that establishes a vertical pathway. The hoistway has an interior border established by a plurality of stationary boundaries that each have a height aligned with a vertical length of the hoistway. Each of the stationary boundaries has a width generally perpendicular to the height. An elevator car is within the hoistway. At least one vertically extending load bearing assembly includes a plurality of elongated load bearing members extending along a vertical path and facilitating movement or support of the elevator car. At least one hoistway liner assembly is situated in the hoistway. The hoistway liner assembly includes a plurality of bumpers that each have an axis that is generally perpendicular to the vertical length of the hoistway. The axes of at least two of the bumpers are non-parallel. The bumpers collectively establish a protected area sufficient for preventing contact between the load bearing assembly and the interior border of the hoistway if there is lateral movement of any of the load bearing members relative to the vertical path in at least two generally perpendicular directions.

A door system for an elevator installation having an elevator car with a car door arranged to travel in an elevator shaft with shaft doors, wherein the car door is spaced from the shaft doors in a closed position of the door system. A primary pivot spindle is coupled to a pivotable door leaf of the shaft door or the car door and a secondary pivot spindle is coupled to a pivotable door leaf of the other of the car door and the shaft door. A drive unit includes a driven, pivotably mounted shaft to which a first entrainer and a second entrainer are fixed. During a pivoting movement of the shaft, the first entrainer engages a first counterpart element on the primary pivot spindle and the second entrainer engages a second counterpart element on the secondary pivot spindle to effect a pivoting movement of the door leaves.

A door system for an elevator installation having an elevator car, the door system including a pivotable first car door leaf mounted at a car door opening and a pivotable first shaft door leaf mounted at a shaft door opening of the elevator installation. At least a part of the shaft door opening is closed by the first shaft door leaf in a closed position thereof and a shaft door plane is formed along the shaft door leaf. At least a part of the car door opening is closed by the first car door leaf in a closed position thereof and a car door plane is formed along the car door leaf. The car door leaf, in an open position thereof, extends through the shaft door plane, or the shaft door leaf, in an open position thereof, extends through the car door plane.

An apparatus for collecting energy in connection with a sheave system in a hoisting apparatus provided with a sheave system. The apparatus includes at least one generator including a rotor and at least one stator. The rotor is connected rigidly to a sheave of the sheave system, and the at least one stator is connected rigidly to the sheave system such that when the load of the hoisting apparatus is rising or lowering, said at least one sheave rotates, whereby the rotor rotates simultaneously but the stator does not rotate, whereby electric energy is induced in the stator. The apparatus further includes electric energy storage, a device for modifying induced electric energy and storing it in energy storage; and a device for supplying energy from the energy storage to at least one consumption device. The consumption device may be, for example, a working lamp, sensor, measuring device, communications device, signal device, charging plug or a combination of these mounted in connection with the sheave system.

A pit switch module of elevator landing door for switching a mode of elevator between an inspection mode and a normal mode comprises a pit switch arranged that ON/OFF operation is configured to be done by an operator at a landing at the state when the elevator landing door has been closed such that the mode of elevator is switched before the operator enters a hoistway or after the operator leaves the hoistway.
