By using-top-of-the-line components and leading-edge designs, Miller Atlas has proven it can handle the most rigorous conditions.

Power The Atlas off-road chassis feature an unbeatable team of drive line components with legendary performance. • A 330 hp CAT engine supplies the power with great fuel economy and excellent cold weather starting. • Smooth, trouble-free transfer of power from an Allison 6-speed automatic “close ratio” transmission with two shift schedules and a transmission oil cooler. • Meritor puts the power to the ground with a double reduction axle with outboard planetary hubs and 2-speed axle ratio. It’s as tough as they come for off-road severe duty use. Speeds You’ll find the perfect speed for every condition and situation. Seven working gears provide an efficient working range from 6.9 to 24 mph at full throttle. Sophisticated air braking system You’ll enjoy excellent stopping power with 4-wheel air brakes. The two frame rails create a huge air reservoir. Frame & front axle Atlas has decades of experience building high strength off-road chassis. High strength steel, 4 walled tubular frame rails with tubular and channel cross members are built to handle the load of a 2000 gallon tank filled with 32% liquid nitrogen and booms 85' wide. EATON wide-track front steer axle with a 6" diameter tube and minimum 15,000 lb. load rating along with twin hydraulic steering cylinders.	Atlas cab and controls The command center is a center-mounted Deere 90 series cab for exceptional visibility and control.
