Hilman Rollers are load Rollers used for moving heavy loads ranging from 1 to 1000 metric tons and beyond. Most Hilman Rollers are all steel, and operate based on the principle of the recirculating chain. This chain is constructed with a series of connected rolls that recirculate around a central load plate set into a framework. The frame acts only to hold the load plate in place, and can include a top plate to ease connection to the load. The rolls spread the load evenly on the load surface providing a low friction, easy to control, high capacity moving device. Hilman Rollers are used in industrial, civil engineering, and heavy construction markets worldwide as machinery dollies, load skates, slides, low profile wheels or casters, guides, linear bearing of sorts, even heavy duty conveyors. They are equally functional right-side-up, upside-down, or vertically and are widely used for temporary one-time moves, permanent and semi-permanent load moving.
