Ram Maintains Underground Approval

Posted on June 29, 2011

Cummins announced the certification of a Mine Safety and Health Administration (MSHA)- approved Cummins 6.7 L Turbo Diesel for the Ram underground mining truck. The specially calibrated engine, which powers the Ram underground mining pickup, is rated 175 hp and is the only truck engine certified by the MSHA for use in coal and metal/nonmetal mining for all 50 states, Cummins said.

The MSHA certification is based on the truck's combination of high payload, a low-emissions engine, and maneuverability in confined spaces. The engine is a lower-emissions version of the Cummins 6.7 L Turbo Diesel used in standard on-highway Ram Chassis Cab trucks. The engine's programming and rating have been modified to a mining calibration – which yield a 42% particulate index reduction and a ventilation rate decrease of 10% from the previous certification - and built to tolerate higher sulfur fuel levels that may exist outside the United States.

Beyond the specially rated MSHA-approved Cummins engine, the underground Ram can be equipped by trained upfitters with protection systems such as automatic fire suppression, wire shielding, marine-grade fuel lines and thermal trip wires. The underground Ram is available now in the United States and Canada and comes in several configurations.
