Gravity conveyors are used to move loads up to 5000 lb down an incline, without utilising motor power. Raptor Supplies offers a wide range of gravity conveyors from brands like Ashland, HTC, Mallard, Grainger and Vestil. Gravity roller conveyors have a steel frame integrated with elevated rollers, to allow them to move smoothly on a downward path. These conveyors are suitable for handling cartons, boxes and equipment with rigid & firm bottoms. Roller conveyors for scissor tables are made from zinc-plated steel to provide impact & wear resistance, and are ideal for moving loads up to 2000 lb. Selected models have ball bearings for low friction and resistance to angular misalignments.
