Abstract
A track is provided by a series of rigid or semi-rigid members supported solely or principally at their ends to extend across the track at spaced locations along the track. A load-transfer device is provided to engage with the track for movement along the track. The device comprises at least one rotary wheel having several equally spaced recesses provided in its periphery and a guide member mounted on the wheel, the wheel and guide member having cooperating relatively rotatable surfaces to allow rotation of the wheel relative to the guide member. The rigid or semi-rigid members are received in respective recesses in the wheel when the device moves along the track and the wheel rotates relative to the guide member to allow such members to pass through the device with at least one of those members being located with respect to the wheel by the guide member at any one time.
