Tommy Gun A3 Fireproofing Series of mortar machines has been redesigned for increased durability and ease of use, with an operator-friendly hydraulic lift and dump mixer, and a smaller, more rugged frame. Instead of the previous manual dump, the new Tommy Guns feature a redesigned 13-cu-ft hydraulic lift and dump mixer with a load height that has been lowered more than 12 in., reducing physical strain on the operator by placing the bag breaker at hip level, rather than shoulder height.
