<p>A drive unit for a reciprocating floor conveyor has a piston component (90) with an outer end longitudinally fixed to a transverse mounting member and a movable cylinder component (92) with a tubular extension (102). A slide bearing (104) supports and guides the tubular extension (102). The drive unit, including the tubular extension, acts as a structural beam. In a first embodiment, each floor member of the conveyor has its own drive unit to provide a powerful drive assembly for heavy loads. In a second embodiment, a plurality of drive units are part of a compact frame (302) having two longitudinal frame members (308) and two transverse mounting members (304, 306). The drive units are mounted in a window defined by the frame (302). A plurality of transverse drive beams (330), one for each drive unit, are connected to the drive units and reciprocate between the transverse mounting members (304, 306). This provides a compact and lightweight drive assembly that may be used for lighter loads. <IMAGE></p> |
