The rolling resistance of a railcar or cart with steel wheels on steel rails is much less than by using a cart with rubber, steel, or hard plastic wheels on normal surfaces like concrete, asphalt, or sand. The V-Move tug can pull a lot more weight when the items are on rails when properly configured, versus pulling on normal surfaces such as concrete. See our example video of a V-Move XXL pulling both an electric locomotive mover and a railcar at the same time: https://www.xerowaste.ca/electric-tugs/v-move-xxl-4-kw-electric-industrial-tug/

If you have a factory and want to use a less-powered and more affordable V-Move tug to move a heavy load, then it may benefit you by installing and placing your load to move on rails instead of pulling a cart on casters across a concrete floor.
