Cat intros PM820, PM822, PM825 cold planers with grade control integration

Caterpillar has introduced three new cold planer models that the company says are capable of controlled, full-depth removal of asphalt and concrete pavements in a single pass.

The new PM820, PM 822 and PM825 are each powered by a Cat C18 engine producing 755 horsepower. The turbocharged C18 features an air-to-air after-cooling system with a variable-speed fan. Cat says the engine “responds quickly to operating demands while keeping exhaust temperatures low and maintaining needed airflow.”

Liebherr details testing on diesel-electric T 236 haul truck prototype

Unveiled as a prototype last year at MINExpo, Liebherr’s 100-metric-ton T 236 is now going through field testing at the Erzberg Iron mine in Austria. Editors got a look at the diesel- electric drive truck in its test environment at a press event held in late October.

“The Erzberg mine gave us a package of testing capabilities that are rare,” says Dr. Burkhard Richthammer, managing director of design and engineering, Liebherr Mining Equipment. For example, the mine has an existing fleet of 100-metric-ton trucks, offering Liebherr a way to directly compare the T 236 with competitive machines.
