In order to make a dedicated concrete work truck, you pair a concrete superstructure with a major engine and truck brand chassis.
The following types of dedicated work trucks place the superstructure on a truck brand chassis - refuse, concrete, road / street sweeper, environmental, vacuum, tree, logging, towing and recovery, boom trucks and emergency services.
Major brands include Freightliner, Western Star, Mack, International, Volvo, AutoCar, Peterbilt, Kenworth, Navistar, Sterling.
Special concrete transport trucks (in-transit mixers) are made to mix concrete and transport it to the construction site. They can be charged with dry materials and water, with the mixing occurring during transport. They can also be loaded from a "central mix" plant; with this process the material has already been mixed prior to loading. The concrete mixing transport truck maintains the material's liquid state through agitation, or turning of the drum, until delivery.

WE CAN DO IT. WE CAN REPAIR ANYTHING YOU HAVE!
Diesel Cast Welding produces new and remanufactured cylinder heads, engine blocks, connecting rods, crankshafts and also can repair these broken parts! Diesel Cast started remanufacturing cores and repairing diesel cast parts 84 years ago in 1936. Our work has always been produced to OEM standards and warranties. Diesel Cast Welding continuously receives calls for a wide variety of diesel engines. There are over 250 diesel engine manufacturers with over 25,000 engine models, series, castings and other variations. Also, since diesel engines last for twenty to thirty years many models are not supported by the OEM manufacturer. Because of this extraordinary array, we can only stock about two thousand of the most popular models. However, Diesel Cast Welding can also repair all of these items for customers at half the cost of a new OEM item. And all of these products are produced at OEM standards and warranties.
