Moving and pouring Self-Leveling Concrete becomes a one-person job with the Self-Leveling Big Tipper Cart. Strong steel construction creates a frame to hold and move a 15-gallon mixing barrel, sold separately. Center support acts as a belt to secure and lock the barrel into place during use. Unique handle design for a compact footprint. The handle can be used to push around a job site and then can be tilted forward to pour the contents of the barrel. The base is connected to 4 swivel rubber castors. Two of the casters lock into place to secure the cart when pouring. Proudly made in the USA. Free Shipping to a commercial business address or local freight terminal.
