A rodless slide assembly comprising; a longitudinally-extending cylinder having first and second ends and a path of travel extending therebetween; a carriage (6', 6", 6"') slidable on the path of travel on the cylinder between the first and second ends; wherein the carriage has a centerline located substantially transverse to the path of travel; a catch assembly (84, 134), comprising a catch bar (96, 140, 242), located adjacent the path of travel of the carriage; wherein the catch assembly has a centerline located substantially transverse to the path of travel of the carriage; and a stop assembly (40, 80, 130, 240) coupled to the carriage; characterised in that the stop assembly comprises: a stop block (62, 86, 136); first and second shock absorber assemblies (60, 92, 138), each located on opposite sides of the stop block, wherein each shock absorber assembly comprises a movable rod (68, 114, 192) to dampen any impact force created during contact between the catch bar and stop block, and wherein each rod is movable along a first and second stroke, respectively; wherein upon contact between the catch bar and the stop block the carriage is decelerated and comes to rest so that the centerlines of both the carriage and the catch assembly are substantially coincident to each other; and wherein the rod of the first shock absorber assembly is compressed along substantially its full stroke. a longitudinally-extending cylinder having first and second ends and a path of travel extending therebetween; a carriage (6', 6", 6"') slidable on the path of travel on the cylinder between the first and second ends; wherein the carriage has a centerline located substantially transverse to the path of travel; a catch assembly (84, 134), comprising a catch bar (96, 140, 242), located adjacent the path of travel of the carriage; wherein the catch assembly has a centerline located substantially transverse to the path of travel of the carriage; and a stop assembly (40, 80, 130, 240) coupled to the carriage; characterised in that the stop assembly comprises: a stop block (62, 86, 136); first and second shock absorber assemblies (60, 92, 138), each located on opposite sides of the stop block, wherein each shock absorber assembly comprises a movable rod (68, 114, 192) to dampen any impact force created during contact between the catch bar and stop block, and wherein each rod is movable along a first and second stroke, respectively; wherein upon contact between the catch bar and the stop block the carriage is decelerated and comes to rest so that the centerlines of both the carriage and the catch assembly are substantially coincident to each other; and wherein the rod of the first shock absorber assembly is compressed along substantially its full stroke. a stop block (62, 86, 136); first and second shock absorber assemblies (60, 92, 138), each located on opposite sides of the stop block, wherein each shock absorber assembly comprises a movable rod (68, 114, 192) to dampen any impact force created during contact between the catch bar and stop block, and wherein each rod is movable along a first and second stroke, respectively; wherein upon contact between the catch bar and the stop block the carriage is decelerated and comes to rest so that the centerlines of both the carriage and the catch assembly are substantially coincident to each other; and wherein the rod of the first shock absorber assembly is compressed along substantially its full stroke.
