Review on Swivel Tipping - Heavy Duty Capabilities Unleashed by Jeremy Camacho

The trolleys are well made and durable I think they have a design flaw The nuts and bolts that you use to attach the rollers are located right where the rim of the 30 gallon plastic barrel would sit Bolt heads and Hex nuts have sharp edges, and I'm sure the heavy weight of a loaded barrel sitting on a sharp edge will pose a problem for a short while to make the effort if a little better design would have fixed the problem.
