Description

The 120M Motor Grader (MG) is a six-wheeled, commercial, construction grader for use by engineering military units. The vehicle is designed and manufactured by the Company Caterpillar.The 120M Motor Grader features all-wheel drive, articulated frame steer, pneumatic tires, electrohydraulic joystick control operation, and an automatic power shift transmission with eight forward and six reverse speeds. The military version of this equipment has several additional benefits over the commercial such as more reliable performance in extreme weather and an armored crew protection kit that can be installed. The new high-tech grader uses six computers to operate. The 120M Motor Grader with ROPS/FOPS removed is designed to be capable of roll-on/roll-off transportation by C-130J, C-5 av-17 military transport aircraft. The 120M Motor Grade is in service with the U.S. army. The first vehicle was delivered in September 2012 to the 130th Engineer Brigade of U.S. army. The South Dakota Army National Guard’s 842nd Engineer Company is the first Army National Guard unit to receive four new 120M motorized road graders during a fielding ceremony May 17, 2012, in Sturgis, S.D.

Technical Data

Design and protection

The 120M Motor Grader is equipped with a completely enclosed rollover protective structure/falling object protective structure/falling object protective structure (ROPS/FOPS) cab, with air conditioning, heating, one primary door, and one secondary exit. The 120M front frame is a formed structural carbon steel tube. Advanced fabrication technology significantly reduces the number of weld joints, which more evenly distributes stress loads. The result is a robust machine that delivers the durability you expect from Caterpillar. The armored crew protection kit (CPK) on the 120M was developed with the Troops’s protection and survivability in mind. The armored cab provides the operator with 360° protection, including the roof and the door, from small arms and fragmentation threats. An emergency egress hatch is provided thru the roof and is accessible from both the inside by the operator and from the outside by rescue personnel. The transparent armor provides excellent operator visibility of the machine and surrounding work area. These features of the CPK allow the soldier to complete military tasks safely and effectively.

Mobility

The 120M combines power management with ACERT™ Technology to deliver maximum power and efficiency while reducing the environmental impact. The C6.6 engine with ACERT Technology uses multiple injection fuel delivery to precisely shape the combustion cycle. Several small ignitions lower combustion chamber temperatures, generates fewer emissions and optimizes fuel combustion. Bottom line: more work output for your fuel cost.

Accessories

The 120M MG features a revolutionary cab design that provides unmatched comfort, visibility and ease of use, making the operator more confident and productive. Two electro-hydraulic joysticks reduce hand and wrist movement as much as 78% compared to conventional lever controls for greatly enhanced operator efficiency. The intuitive pattern is easy to learn and provides the precise implement control you expect from Caterpillar. The Cat® Comfort Series suspension seat has an ergonomic high-back design, with extra thick contoured cushions and infinitely adjustable lumbar support that evenly distributes the operator’s weight. Multiple seat controls and armrests are easy to adjust for optimal support and comfort all day. The optional air suspension seat enhances ride quality for additional comfort.

Combat use

The 120M MG provides coarse and fine grading, low- and high-bank sloping, flat- and V-ditching, and scarifying materials to support military road, bridge, and airfield construction.
