Abstract: A mechanical handling apparatus comprising a support surface for supporting a load, and a plurality of rollers, each roller being rotatably mounted on an axle for moving a load over the support surface, the support surface comprising an aperture for each roller so that either the rollers or the support surface can be moved between a first position in which at least a part of each roller is proud of the support surface and a second position in which each roller is substantially flush with or recessed below the support surface, and at least two rollers being mounted on each axle.

Abstract: 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.
