QST30 for Mining

While fuel efficiency is important, the key to mining profitability is equipment availability. The QST30 combines proven reliability and durability as well as excellent fuel economy for the lowest cost-per-hour of operation.  The durability of the base engine is well proven, with thousands of QST30 engines in haul trucks, blast hole drills and wheel loaders delivering superior uptime worldwide. Sophisticated electronic controls and flexible calibrations so you can custom-tailor your engine's performance to its equipment, work environment and job demands.  The standard features of an integrated water pump, lube pump and cooler housings with metric O-ring fittings eliminate potential leak points for increased reliability.

The QST30 is an excellent choice for every mining application - whether installed in new equipment or upgrading an engine in an existing machine.  With ratings from 760-1200 hp (567-895 kW), it produces up to 25% more power and torque, with better fuel economy and longer service intervals than the typical engine it replaces.

Cummins QST30 for Emissions-Regulated Mining Applications

The QST30 has ratings available to meet every emissions regulation worldwide including EPA Tier 2. Modifications to the base QST30 engine to meet legislated Tier 2/Stage II emissions levels for both U.S. and European regulations include an upgraded turbocharger and intake system, as well as a modified fuel spray pattern and a re-contoured piston bowl. These changes provide better combustion with fewer emissions, while maintaining the structural integrity, reliability and durability that have won the QST30 its hard-earned reputation for low cost-of-operation and exceptional life cycle value. Its enhanced fuel economy and long service intervals make it an excellent choice for repowers, especially when cost and productivity are taken into consideration.

Every QST30 engine is covered by Cummins base warranty, one of the most comprehensive and simplest plans in the industry.

QST30 customers also benefit from reduced maintenance and exceptional customer support.
