Front-Discharge Mixer Truck Features Shorter Turn Radius And Dozens Of Upgrades
The Terex FD4000 front-discharge mixer truck boasts significant steering and front suspension improvements that enable the truck to take advantage of the front axle’s full-wheel-cut capability, significantly reducing the turn radius. Curb-to-curb turn radius is now a maximum of 68 feet (20.7 m). This is a 15 percent reduction from previous models, improving on-site maneuverability. At the same time, the wheel base on the FD4000 mixer truck has increased by 12 percent to 208 inches (528 cm) for better weight distribution, ride quality and operator comfort.
More than 20 upgrades have been made to the operator’s cab, highlighted by 8.5 inches (21.6 cm) of additional floor space, making it more comfortable for taller operators. Its redesigned dashboard features logical positioning of gauges for improved operating efficiency. A stair-rail handle and flexible hanging third step make cab access easier.
Customers can choose between two 2013 EPAcompliant engines, offering the latest in emissions control technology, for the FD4000 mixer truck. The MTU DD13 diesel engine can be configured to provide 350, 380 or 450 hp (261, 283 or 336 kW) to meet application needs. Alternatively, customers can opt for the Cummins ISX12 engine, offering three different power ratings of 350, 385 or 425 hp (261, 287 or 317 kW). In the summer of 2014, customers will also have a 400-hp (298-kW) compressed natural gas (CNG) engine option. A standard on-board diagnostic (OBD) system provides self-diagnostics of emission system components and reports through a CAN-bus connection to help operators monitor the working condition of all EPA-required components.
The standardized 11-cubic-yard (8.4-cubic-metre) mixer drum on the FD4000 truck excels in transporting and discharging low-slump concrete. Its drum shell is constructed with AR400 steel, and 0.25-inch (0.64-cm) thick AR230 steel fins and flights in the mixing area improve wear resistance. Bolt-on trunnion rollers provide easier adjustment and simplified servicing.
To improve the truck’s service-life longevity and reduce corrosion, components are pre-primed and powder coated. The mixer truck’s air system features more than a hundred part-count reduction from previous models, resulting in fewer connections for less air leakage potential. The lift axle is controlled by a single lift-axle control module (LACM), which replaces four valves per axle, improving system servicing ease. Wiring harnesses are efficiently routed to improve electrical system reliability, while stop/turn/tail, back-up and license plate lights use LED lighting for longer life.
