Agility Fuel Systems for the CNG Array Using Hexagon Lincoln Tanks
As ISX12 G Said to Make CNG Version of FD5000 ‘Great Lakes’ Possible
Terex is showing its first concrete mixer truck powered by compressed natural gas at the CONEXPO-CON/AGG 2014 show in Las Vegas – a CNG version of the front-discharge FD5000 “Great Lakes.”

The truck is powered by the 11.9-liter ISX12 G engine by Cummins Westport. A two-tank design by Agility Fuel Systems using all-composite Type IV CNG cylinders from Hexagon Lincoln saves weight.
“Previous 9-liter engines available on the market didn’t provide the power or torque required for our customers and their applications,” Terex Construction sales and marketing director of Dave Rinas says in a release.
Orders in Hand
The engine is available in 350-, 385- and 400-horsepower packages. “The 12-liter engines deliver the required performance and a substantial fuel cost savings benefit when compared to diesel engines,” Rinas said.
“We already have several customer orders for the CNG trucks.”
“Terex CNG trucks feature an integrated design approach,” the company says, noting that CNG engines are available for the firm’s entire line of standard and federal bridge formula front discharge mixers – from three to seven axles. The CNG engines can also be ordered as part of the Terex glider truck program.
Agility Has Orders for Eight More
“Everything below the frame rail and forward of the rear pedestal is the same as on our diesel mixer trucks,” Terex design engineer Mike Johnson says in the announcement. “The CNG system eliminates much of the complexity that goes along with 2013 EPA-compliant engines, while still reducing hydrocarbon emissions,” he said.
Terex mounts a single 26-by-80-inch Type IV tank from Lincoln Composites to each side of the rear frame, allowing 75-DGE (diesel equivalent gallon) worth of fuel.
“We designed, supplied and installed the complete fuel system,” says Agility sales and product report VP Scott Lucero. Agility has orders in hand for eight more trucks, he told F&F.
‘New Integrated Terex Look’
“The design delivers a lower center of gravity compared to other installations; reduces the number of required tanks, hoses and tank safety systems by 50%; and places all tank safety shut-off valves, fill ports and service items at ground level,” Terex says. The “unique mounting approach features a spherical bearing design that allows for tank length and diameter expansion/contraction when filling and compensates for frame flexing when driving in off-road conditions, unlike the rigid strap-mount of competitive tank designs.
“The two-tank Terex CNG configuration reduces weight by up to 25% over other designs,” the company adds, improving payload. “Up to 50% of internal steel was removed from the new engine cowling for CNG trucks – further reducing truck weight to improve payload capacity – while the design’s new ribs and contours add strength and style for this new integrated Terex look.”
