ELEVATORS

摘要

An elevator car assembly (10) comprises at least one runner (40) for engaging a wall (34) of a hoistway (30) such that the car assembly (10) may move within the hoistway (30) with the runner (40) in contact with the hoistway wall (30). The runner is preferably a wheel (40). The wheel (40) counteracts turning moments generated due to an offset between a suspension point of the car assembly (10) and its centre of gravity. Wheels (40) are preferably provided at a lower part of one side of the car assembly and at an upper part of an opposite side of the car assembly (10).
