Ingersoll Rand has entered the milling market with the introduction of two milling machines, the MW-500 and MT-2000. The company plans a full product range of six milling machines with cutting widths from 20 inches to 14 feet.
The MW-500 is a four-wheel, rear-loading, utility-class milling machine that offers a standard cutting width of 20 inches. Because of its compact size and maneuverability, applications include patching, trench and shoulder milling.
A 125-hp Deutz diesel engine powers the MW-500. An independently driven cooling fan is designed to ensure trouble-free operation even at high ambient temperatures. The fan automatically switches on and off as required, for reduced noise and fuel consumption.
The four-wheel MW-500 has an extremely tight cutting radius of 7 inches. The right rear support leg and wheel can be swivelled inboard for flush cutting. The MW-500 offers all-wheel-drive for optimal traction and features Anti-Slip Control (ASC) as standard. The patented Line Manager system works in conjunction with the ASC to allow the operator to maintain a constant speed of operation and direction of travel without being adversely affected by the rotation of the milling drum.
The 30-inch-diameter drum offers a maximum cutting depth of 8.25 inches with a standard cutting width of approximately 20 inches. The MW-500 includes hydraulically raised drum side skirts and rear moldboard to improve material containment and drum access.
The fully enclosed conveyor can be adjusted up and down and is capable of moving side to side up to 25 degrees in either direction. The conveyor can be easily removed via a quick coupling device for mill-in-place operations.
The MW-500's operator's platform features an adjustable steering wheel and control panel for optimal ergonomics. This platform provides the operator a 360-degree view of the working area and excellent visibility to the drum.
The MW-500 is designed with serviceability in mind. All daily check points and routine maintenance locations are available via access doors. A swing-out valve block allows access inside the engine compartment. A back-up raise and transport panel is available for emergency operation.
The MT-2000 is a four-track, front-load, half-lane milling machine powered by a 600-hp Tier 3 Cummins engine.
The MT-2000 offers three distinct drum cutting speeds. The deep-cut power bulge feature provides higher torque at lower engine revolutions per minute to power through tough material or deep-cut applications. The high-speed selection is for maximum speed on shallow cutting depths. The standard cutting speed is used to provide maximum horsepower and efficiency at normal cutting depths.
The MT-2000 can run both 78.75-and 86-inch drums. The drum and housing are easily removed together to reduce time and complexity during interchange. The drums are available with weld-on or quick-change tooth holders and fine or standard tooth spacing patterns. Specialty drums are available upon request.
The four-track system offers innovative features to improve performance. With five steering modes, the MT-2000 is the most maneuverable machine in its class. In addition to front, rear, coordinated and crab steering modes, circle steer is now available for the tightest turning radius possible. An independent slope sensor alerts the operator if the machine is out of an acceptable range and adjusts the support legs to level the machine.
The 36-inch-wide gathering and discharge conveyors are independently controlled with variable speed adjustment to meet the capacity of the cutting drum. The theoretical capacity of the conveyor system is 1,330 cubic yards per hour. A pressure monitor in the discharge conveyor is designed to slow the machine to prevent overloading of the conveyor system. Both conveyors are hydraulically tensioned and incorporate maintenance-free bearings for improved performance, and each uses a water spray bar for dust suppression.
