The company's glider program offers customers a way to upgrade front discharge mixers with an array of component and system options-turning an old mixer into new. The glider process begins by disassembling a donor truck to identify viable components. These parts are prepped and upgraded for installation, and then the glider's assembly is completed. The process takes a few weeks and can be a 60% savings compared to the cost of a new truck. Terex Roadbuilding. 888-837-3972.
