To provide an apparatus for suspending, moving or fastening a load or locating a member which is loaded in use and where in each case the load or loaded member may be required to be movable in use, the invention provides a mesh for location in a desired position for suspending or locating the load. An attachment device for the load comprises a wheel having a number of spaced recesses and a co-operating location member mounted on a peripheral part of the wheel with relatively rotatable bearing members therebetween to allow the wheel to rotate relative to the location member. The wheel is engaged with the mesh with its plane generally perpendicular to the mesh such that elements of the mesh are received, guided and passed in the recesses on the wheel as the wheel moves through the mesh while being located with respect to the mesh by the location member. |
