Abstract
A conveyor chain trackway to receive a chain. The chain has first and second links, the latter alternating with the first. Each first and second link comprises a pair of spaced side members. There is a pivotal joint between neighbouring links. Spikes are formed on a plurality of first links to receive and locate a load. The trackway comprises a base member in the low friction layer on the base member and dimensioned to receive the second links. Side plates are spaced from each side of the base member. The side plates extend upwardly to be alongside the chain when the chain is in position. The side plates can be adjusted on the base to vary the distance from the base. Low friction distance pieces on the inner side of the side plate extend to contact and locate the chain. The chain is thus held on a fixed course and movement inwardly of the low friction distance pieces can compensate for wear in the chain.
