A load transfer device comprises a pair of spaced-apart rotary members (101, 102), each having at least one recess formed in its periphery and sharing a common axis of rotation. A slipper member (110) is located between the rotary members (101, 102) and defines therewith a space (150) adapted to receive an elongate support element (190) (not shown) along which the device travels in use. Means are provided for attaching a load to the device. The rotary members (101, 102) are rotatably mounted in relation to the slipper member (110) and their recesses are adapted to traverse intermediate brackets (not shown) for said elongate support element without user intervention. The limbs of said intermediate brackets are successively received, guided and passed by the recesses automatically. Access means (123) (not shown) are provided to enable said elongate support element to be introduced into or removed from said space (150) to enable the device to be attached to or removed from the elongate support element.
