ABSTRACT:
The load supporting and moving surface of the conveyor is made up of longitudinal members called slats. The slats are edge to edge with small gaps between the edges. The slats are supported on bearing parts and bearing strips which are supported on longitudinal beams which are evenly spaced and extending lengthwise of the cargo space of the conveyance in which the conveyor is installed. The longitudinal beams are supported by and fastened to the cross beams of the conveyance. The longitudinal beams, bearing strips, bearing parts and slats of the conveyor are all installable from directly above the cross beams. The slats are held in place vertically by interlocking with the bearing parts. There is a juncture formed at every contact between a longitudinal beam and a cross beam. Bearing parts are installed a 10% to 50% of the junctures. The conveyor also comprises means to reciprocate the slats a stroke length. The longitudinal length of each bearing part is between 0.5 and 0.95 of the stroke length.
