The Ingersoll Rand MT-2000 is a four-track, front-load, half-lane milling machine powered by a 600-hp (447 kW) 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-in. (2,000 mm) and 86-in. (2,185 mm) 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 features to improve performance. With five steering modes, the MT-2000 is maneuverable. In addition to front, rear, coordinated and crab steering modes, circle steer is now available for the tightest turning radius possible. Tapered bearings in the rollers reduce track overheating. Active anti-spin control transfers power from a slipping track to improve traction and provide greater control. 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-in.-wide (91 cm) 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 cu. yds. (1,017 cu m) 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. Each conveyor utilizes a water spray bar for dust suppression.
The dual operating stations on the MT-2000 have four-way sliding seats and console storage compartments. The control panels adjust to accommodate an operator who is seated or standing and move laterally for ergonomic operation. The right-side platform and stairs provide a secondary access point and fold away for flush cutting. The MT-2000 includes 14 lights for work at night.
The MT-2000 incorporates advanced technology with intuitive operator panels that are easy to understand and operate. The back-lit membrane switches are color-coded to match the area of function on the machine. Each control panel includes a brightly illuminated display area that allows the operator to view the master control screen or one of eight different diagnostic screens. Diagnostic screens include in-depth information on the engine, hydraulics, truck loading and grade controls. Performance messages and diagnostic information are displayed in language, rather than codes. Up to eight different languages are available for communication.
Four ground control panels are conveniently located at each corner of the machine. A ground crew member has the flexibility to control both sides of the machine, and the front or rear, from one grade control station. The MT-2000 has optional sonic grade control sensors that can be plugged into six ground locations. The grade control panels also can be plugged into any of the six locations, plus a location on the operator control area.
Ingersoll Rand offers increased serviceability with a walk-in engine compartment. The engine, hydraulic components, fan and coolers can be easily accessed by the stairs and door to the walk-in engine compartment. The engine fan is reversible, providing the capability to blow out the coolers for improved performance.
