OKLAHOMA CITY, February 19, 2010 – For the 2010 paving season, the Terex® PR950B half/full lane milling machine features a new, quieter C27 Tier II diesel engine and enhanced cooling system. Developing 947 hp (706 kW) at 1,800 RPM, the PR950B offers plenty of power to make up to 15-in (381-mm) deep plunge cuts with its standard 86 in (2,184 mm) half-lane cutter. Operating at a 14 percent reduced engine RPM, the PR950B emits lower noise levels, improving the operating environment around the machine.
The new PR950B design also enhances machine serviceability. Working from a platform, the service technician now has unobstructed access to the engine, filters and hydraulic pumps for servicing. A new service panel offers quick troubleshooting of the hydraulic system to quickly diagnose issues in the field.
A new 20 CFM air compressor available for the PR950B allows service personnel to quickly and efficiently change cutter teeth. In contrast to previous designs that required the machine engine to run for changing teeth, the new stand-alone air compressor is powered by its own 10 hp (7 kW) diesel engine that is much quieter and consumes considerably less fuel. The engine draws fuel from the main diesel tank.
The PR950B milling machine’s quick-mount cutter housing design offers fast removal for simple maintenance and easy cutter change-out. Four cutter widths are now available – standard 86-in (2,184 mm); 103 in (2,612 mm); 135 in (3,429 mm); and full lane 150 in (3,810 mm) – increasing machine versatility to tackle a variety of applications. The exclusive tapered cutter housing carries substantially less material, reducing clean-up. The machine’s high pressure water system with 1,220 gallon (4,618 liter) tank capacity effectively cools the cutter teeth for optimal service life. When tooth changes are required, the hydraulically operated rear cutter door can be raised up to 32 in (813 mm) for unimpeded access to the rotor.
The Terex® PR950B features wide, 42-in (1,067 mm) upper and lower conveyors to quickly channel material away from the cutter, optimizing production capabilities. The upper conveyor swings 60 degrees to either left or right of center, allowing material to be quickly discharged directly into a truck on either side of the machine.
Featuring a hydrostatic drive system, four machine work speeds match cutter productivity to the material being milled. Speeds range from a low of 0 – 74 fpm (0 – 23 mpm) to a high of 175 fpm (0 – 53 mpm) for high production mainline milling.
Available in either a three- or four-track configuration, the PR950B includes all-track drive for maximum traction. All-track steering delivers exceptional on-site maneuverability and a class-leading 8-ft (2,438-mm) turning radius for both track designs.
