Flexible Skate Wheel Conveyor (Extendable Conveyor) by Bakshi Mark is a proven performer for trailer loading and unloading. Ideally suited for packaging, shipping and flexible assembly lines. The main difference is that instead of rollers, these utilize a number of skate wheels on shafts attached to the conveyor frame. The main benefit of a skate wheel conveyor as opposed to a roller conveyor is that they can convey lighter products and can be moved in any direction. These conveyors again need some manual force or an incline to transport the products. They can be collapsed and stretched easily. Common uses for skate wheel conveyors include the handling of boxes, flat bundles, cartons, crates, trays and totes.
