ABSTRACT:
A load attachment system comprises an elongate element secured with respect to a supporting structure and a load attachment, traversing device engaged therewith for sliding movement therealong to traverse intermediate attachment points for the elongate element without detachment therefrom. The traversing device includes a pair of rotary members which cooperate to define a channel for receiving and locating the elongate element. The rotary members are supported on mounting structure adapted to allow relative movement of the rotary member to narrow, or increase, the width of the channel. A load attachment connection is provided on the mounting structure to cause loading of the rotary members, under loads applied in directions away from the elongate element, so as to firmly maintain them in relative positions in which the channel is narrowed thereby securing the elongate element in the channel and reducing the possibility of detachment of the load from the elongate element.
