Terex Roadbuilding announced at the World of Concrete the addition of three new utility mill models to its existing line of mainline cold planers, relaunching the company back into the milling market. Available in the first half of 2007, the new Terex CMI PR165, PR220 and PR330 cold planers will help contractors to quickly and cost-effectively tackle a wide variety of utility milling applications including cul-de-sacs, wedge and header cuts, bridge decks and shoulder excavation.

All three new utility mills feature an efficient hydrostatic rotor drive that includes a built-in relief system, which protects drive components from severe damage should the cutter hit an obstruction. A parallelogram cutter subframe design delivers a 24-in. elevation to lower and raise the cutter in and out of the cut. All three models feature a 36-in. drum diameter, which enables a 12-in. cutting depth for milling and stabilization patchwork.

The mill's "center mount" cutter design positions the full weight of the machine over the rotor, enhancing performance even in the toughest cuts. Four-wheel steering offers four steering modes--coordinated front and rear, crab, front only and rear only--to improve on-site maneuverability. Operators are seated directly above the cutter, maximizing visibility while working around obstructions.

Both the PR165 and PR220 feature a high degree of component commonality, providing customers with the opportunity to reduce inventory costs. These mills are powered by fuel-efficient, Tier 3 and Stage IIIA compliant diesel engines with the PR165 rated at 165 hp and the PR220 rated at 225 hp. The PR165 offers a standard cutting width of 24 in., while the PR220 delivers a 30-in. milling width. A tight, 8-in. inside turn radius allows for cutting around headers and manhole covers.

Large, 36-in.-diam., high-flotation tires with four-wheel drive and a limited slip differential improve tractive effort. Two working speeds of 0-200 ft/min and 0-360 ft/min allow the operator to match machine speed to jobsite conditions. With a high travel speed range of 0-12 mph, these cold planers are quickly roaded to the next cut.

For utility contractors requiring a little more power, production and versatility, Terex Roadbuilding also offers the PR330 multi-purpose milling machine. Powered by a Tier 3 and Stage IIIA compliant, 330 hp diesel engine, the new PR330 has a standard 48-in. cutting width. Available 24- and 36-in. cutting widths maximize machine utilization and versatility.

Customers can specify cutter-drum tool spacing, diameter and width to configure the PR330 for optimum profitability on each specific application. Automatic cutter depth controls are monitored and adjusted from the vibration-isolated operator's platform, and the machine's cross slope feature provides a plus-or-minus 8º slope.

The new Terex CMI PR330 offers the choice between a four-wheel or four-track drive system. Similar to the established mainline machines, this utility mill comes standard with a two-stage, high-capacity conveyor system to quickly remove material from the cutter housing.
