A factory preassembled drive module is assembled between opposed spaced apart ends of load beams and opposed rotatable shafts supported by the load beams are assembled drivingly to a rotatable drive shaft coupling of the drive unit or module in a job site where the overhead conveyor is installed. The drive unit module includes a motor driving a transmission, in turn driving pulleys that drive belts in turn driving the rotatable portion of the drive shaft coupling. The drive motor and transmission are mounted on a bracket with lost motion permitting tension adjustment of the belts, and the bracket is formed with flanges to respectively abut and overlap correspondingly shaped portions of the adjacent load beams for connection thereto.

[ What is claimed is:] [10.]10. An overhead conveyor system, comprising:a plurality of carriages for suspending loads;an overhead powered conveyor for suspending said carriage transporting said carriages serially along at least one conveying path;a stationary frame extending along said conveying path;said overhead powered conveyor having at least one drive having a rotational power output;said overhead powered conveyor having first and second drive shafts with spaced apart aligned distal ends and extending along said conveying path;each of said drive shafts being mounted to said stationary frame for rotation about respective shaft axes parallel to respective portions of said conveying path;said overhead powered conveyor having a power connection between said drive and said drive shafts for rotatably-driving said drive shafts about said shaft axes;said carriages each having a driven wheel rotatable about a driven wheel axis nonparallel and non-perpendicular to said shaft axis, and said driven wheel engaging an engagement portion of said drive shafts with sufficient traction so as to form a helical loci of engagement about the periphery of said drive shafts during rotation of said drive shafts about said shaft axis to power said carriages along the conveying path in a direction of the conveying path dependent upon a direction of rotation of said drive shafts;said carriages suspending the loads vertically below said drive shafts;wherein the mounting of each of said drive shafts to said stationary frame includes two aligned load beams extending along the conveying path and being fixedly connected to said stationary frame, and a plurality of bearings mounted on said load beams rotatably supporting each of said drive shafts;said load beams having spaced apart, aligned and adjacent distal ends respectively adjacent the distal ends of said drive shafts;said power connection including a drive shaft coupling drivingly extending between said drive shaft distal ends and having opposed ends respectively being connected to said distal ends of said drive shafts; anda bracket mounting said drive, said bracket extending between and being connected to said distal ends of said load beams below and adjacent to said drive shaft coupling; andsaid bracket forming the sole support for said drive and said bracket being solely supported by the distal ends of said channels.
