ARRANGEMENT FOR THE TRANSPORT OF MATERIAL ARRANGED PREFERABLY ON A CARRIER FRAME.

摘要

A floor conveyance system for transporting goods along a preselected conveyance path includes a drag chain conveyor defining a first surface and a skid conveyor having one end adjacent to the drag chain conveyor and defining a second surface disposed at a higher level than the first surface of the drag chain conveyor. A conveying frame is operatively engageable with the drag chain and skid conveyors for supporting goods thereon and includes front and rear pairs of wheels to permit for rolling movement of the conveying frame across the first surface and a pair of elongated parallel skid members mounted interiorly with respect to the front and rear pairs of wheels and each having a longitudinal length less than the separation dimension between the front and rear pairs of wheels. The parallel skid members establish sliding contact with the second surface when the conveying frame is conveyed along the skid conveyor. Thus, the front and rear pairs of wheels contact the first surface when the frame is conveyed by the drag conveyor while the pair of skid members are inoperative, and the front and rear pairs of wheels are disengaged from the first surface when the pair of skid members come into engagement with the second surface of the skid conveyor.
