Atlas Copco introduces Tier 4i engines on underground loaders and trucks


Atlas Copco is introducing Cummins Tier 4 Interim engines as an option on five of its underground loaders and one underground truck. The engines provide low emissions and high fuel efficiency.

Scooptram ST7

The Scooptram ST7 underground loader is one of the Atlas Copco loaders that are now available with a Cummins Tier 4i engine.

The Cummins Tier 4i engines will be available as an option on the underground loaders Scooptram ST7, ST7LP, ST1030, ST1030LP and ST14 as well as on the underground truck Minetruck MT2010.

“With the new Tier 4i engines you get lower emissions along with higher fuel efficiency,” says Ben Thompson, Product Manager at Atlas Copco. “It means that you will reduce the fuel consumption but also that you can cut down on the required ventilation and that will result in great savings to operating costs. In addition you will get a healthier working environment for all personnel in the mine.”

The Tier 4i engines feature improved performance and torque response via variable geometry turbocharging and an enhanced fuel system. This can provide up to 5% greater efficiency than the equivalent Tier 3 engine.

The passive regeneration of the diesel particulate filter is automatic with no operator assistance while still maintaining high machine performance. In addition, no diesel exhaust fluid is required for the Cummins Tier 4i which will also contribute to lower costs and fewer production stops.
