ABSTRACT:
The invention provides a guiding arrangement for a skip, cage, lift or the like wherein guide rollers on opposed sides of the skip are urged against guides which flank the skip, each by way of first and second biasing springs. The first biasing spring has a lower load resisting capacity than the second biasing spring and upon a predetermined deflection of the first biasing spring the second biasing spring is brought into action to resist further deflection.
