The McNeilus Company (a subsidiary of Oshkosh Truck) has been producing concrete mixer trucks for the heavy construction industry since 1975. 

• The mixer trucks carry, deliver, mix, and pour concrete on-site and come in a range of load capacities (4 to 15 cubic yards of concrete. A cubic yard of concrete weighs 4000 pounds). 

• The mixer trucks have to reliably deliver concrete across all kinds of terrain and weather.

• Each component of the truck has to be rugged and durable to withstand mixing and pouring stresses as well as road shock and vibration over the life of the truck.

The metal pour chute on the rear of the truck carries the concrete mix from the drum down to the concrete forms. The chute is designed to swing across a 160° arc so that concrete is easily poured into forms without having to reposition the truck.
