This invention relates to improvements in reciprocating floor conveyors. A problem with some reciprocating floor conveyors is that they are not capable of being mounted in relatively narrow spaces. This invention divides the hydraulic drive assembly into two small size assemblies, each of which is capable of being mounted into a relatively narrow space. In each assembly, piston rod portions (42, 45, 44, 48) of two linear hydraulic motors (16, 20, 18, 22) are connected at their opposite ends to two spaced apart transverse frame members (50, 52, 54, 56). A cylinder (84) is driven back and forth along each piston rod (42, 46, 44, 48). Two transverse drive beams (24, 28, 26, 30) are provided. Each drive beam (24, 28, 26, 30) is directly connected to an associated one of the cylinders (84). The transverse drive beams (24, 28) of the first assembly are connected to the first and third set of floor slat members (40). The transverse drive beams (26, 30) of the second assembly are connected to the second and fourth set of floor slat members (40). The two assemblies (10, 12) are axially spaced apart. The linear hydraulic motors (16, 18, 20, 22) are operated for simultaneously moving the floor slat members (40) in one direction, for advancing a load, and for sequentially retracting them in the opposite direction.
