Abstract: A roll-formed steel slat for use in a reciprocating floor slat conveyor system. The roll-formed steel slat is formed in a manner so as to have an upper, load-carrying surface, and a pair of downwardly depending side legs. Each side leg terminates in a foot. One foot is vertically offset from the other to provide a “hold-down” function that prevents the slat from vertically rising as the slat reciprocates back-and-forth.

Abstract: Beams (24, 26) are used to guide the rear end of a trailer (T) into contact with bumpers (20, 22) on the rear end of a dock (D). Longitudinal beams (32, 34) include hydraulic cylinders that are operated for extending and retracting the beam (32, 34). The trailer (T) is backed up against sloping surfaces (100) on the beams (32, 34). Contact between the sloping surfaces (100) and a transverse beam (104) at the rear end of the trailer (T) cams the beam (104) into a position where hooks (102) on the outer ends of the beams (32, 34) can hook onto a shoulder (106) on the trailer beam (104). The beams (32, 34) are then retracted. This moves the beams (32, 34) upwardly onto supports (78, 80), raising the trailer beam (104) a proper height. Continued retraction of the beams (32, 34) pulls the trailer beam (104) into contact with bumpers (20, 22) on opposite sides of the rear end of the dock (D).

Abstract: A slat conveyor includes both lifting slats (10) and conveying slats (12). Longitudinal movement of drive members (34) move lifting blocks (32) up lifting ramps (30). The tops of the lifting slats (10) rest on the lifting blocks (32) and the lifting slats (10) move upwardly with the lifting blocks (32). When the lifting slats (10) are in a “down” position, their upper surfaces are below the upper surfaces of the conveying slats (12). Advancing movement of the conveying slats (12) advance a load (L) that is on the conveying slats (12). At the end of a forward movement of the conveying slats (12), the lifting slats (10) are raised into an “up” position, lifting the load (L) above the upper surfaces of the conveying slats (12). Then, the conveying slats (12) are retracted while the load (L) is held by the lifting slats (10).
