<p>Reciprocating floor conveyor floor members (28) are moved by hydraulic cylinders (1,2,3) which are slightly tilted so as to exert a vertical component of force onto the ends of longitudinal drive beams (132, 134, 136) to which the cylinders (1,2,3) are connected. These beams (132, 134, 136) are made from tubular stock. Each is guided by a pair of longitudinally spaced apart bearings. Each bearing is a part of a bearing assembly (130, 131) which depends from an upper central portion of a transverse truss (80,82). Each longitudinal drive member (132,134,136) is welded to a transverse drive beam (10,12,14) by fillet welds on each side of the longitudinal drive tube (132,134,136). Each such drive tube (132,134,136) is stiffened in the region of the weld by a short tubular insert which is rammed into the drive tube. The floor members (28) of the conveyor run on plastic slide bearings (26) which are snap fitted onto longitudinal guide beams (22).</p> |
