Abstract: A hydraulic cylinder for a drive unit assembly for a reciprocating floor slat conveyor system has a single tubular barrel divided into two chambers by a center head or plug. The center head is held in position by shrink fitting it into the barrel.

Abstract: A truck cargo lift gate is pivotable between an upstanding and horizontal position. The lift gate carries a low-profile, endless chain conveyor. After the lift gate is pivoted to the horizontal position, the lift gate and the chain conveyor carried thereby may be vertically lowered to the ground with a load on the lift gate.

Abstract: The load conveyer system includes a pair of rails that carry endless chains. Each rail is an extrusion that has extruded side channel portions that allow the adjustable positioning of mounting bracket fasteners. This allows mounting brackets to be used to removably mount the rails to a preexisting floor surface without substantially modifying the floor during the rail installation or removal process.

Abstract: An endless chain conveyor is disclosed having an endless chain that rides on a rail with sprockets at each end of the rail. The chain is installed on the rail in tension. The conveyor does not otherwise require an adjustment mechanism for taking the slack out of the chain after it is installed on the rail.

Abstract: The load conveyer system includes a pair of rails that carry endless chains. Each rail has its own dedicated drive motor that operates independently of the other. The motors are sized to fit within the vertical height or vertical envelope of the rail, so that the motor does not interfere with movement of the load carried by the rail. Each rail and drive motor are independently mountable to an underlying support surface as a module.

Abstract: An all-aluminum cross-drive member for a drive unit assembly that is used to reciprocate floor slats back and forth in a conveyor system, The cross-drive member is extruded or milled from a single piece of aluminum, One side of the member carries connecting pieces for linking the member to floor slats, with the member driving the floor slats back and forth as the member is likewise moved lengthwise in back and forth movement, The other side of the member has stiffening ribs that extend lengthwise for giving the member sufficient stiffness to carry loading forces in lieu of the steel cross-drives used in the past.
