Profile: Pitts Engineering Works supplies construction machinery parts, agricultural tractor parts, aerospace parts, and concrete equipment. We specialize in concrete mixing trailers. Concrete Titan™ 125E has a full 1.25 cubic yard (956 liter) capacity. Our Concrete Titan™, with a GVWR of 9,800 lbs (4,445kg), can easily handle full loads of concrete. We use closed-center hydraulic valves for the Concrete Titan™. The control lever for drum rotation speed & direction allows smooth starts & stops with no sudden forward-neutral-reverse shock loads, and the speed is infinitely-variable in both directions, with a single lever.
