Abstract
A load transfer device comprising a pair of spaced-apart rotary members, each having at least one recess formed in its periphery and sharing a common axis of rotation. A slipper member is located between the spaced-apart rotary members and defines therewith a space adapted to receive an elongate support element along which the device travels in use. A positive locking mechanism is also provided for attaching a load to the device in order to prevent accidental release of the load from the device. The spaced-apart rotary members are rotatably mounted in relation to the slipper member and their recesses are adapted to traverse intermediate brackets provided for the elongate support element without user intervention. The limbs of the intermediate brackets are successively received, guided and passed by the recesses automatically. The elongate support element may be introduced into or removed from the space defined by the spaced-apart rotary members to enable the load transfer device to be attached to or removed from the elongate support element.
