Tommy Gun A3 fireproofing series of mortar machines have increased durability and ease of use, with an operator-friendly hydraulic lift and dump mixer, and a smaller, more rugged frame. Replacing the manual dump on the previous series, the new Tommy Guns have a 13-cubic-foot hydraulic lift and dump mixer with a load height that has been lowered more than 12 inches. This places the bag breaker at hip level, rather than shoulder height. The hydraulic controls are located at the rear of the unit, adjacent to the mixer. The Tommy Gun A3 Series is available in both plaster and fireproofing configurations.
