A load handling trolley for use on a channeled track is provided that includes an elongate load engager and bogies. The load engager is raisable and lowerable relative to the bogies via a ramp and rollers when the bogies are caused to move longitudinally relative to the load engager. Relative movement is controlled by a lever operated crank which is pivotally mounted with respect to the elongated load engager and which operates links pivotally connected between the crank and the bogey chassis. An abutment is operable between the links and the bogey chassis to limit the angular movement between the links and the bogey chassis. This permits the raising of the load engager when an end thereof partially projects beyond the end of the channeled track. Additional angular movement of the lever operated crank beyond that required to attain the limit position is allowed for by relieving an end plate of the trolley. A cleaning pad can also be positioned at the load and trailing ends of the trolley to provide cleaning of the full width of the channeled track.
