Cummins QSK19 And QSM15: Mining-Grade Power, Explained

QSK19 — the 19-litre mining workhorse

The Cummins QSK19 is a 6-cylinder, 18.9-litre engine rated roughly 500–750 HP depending on configuration. It powers mining trucks, large excavators, heavy haulage and high-output gensets. Its PT/common-rail fuel system and structural strength make it the default choice where downtime costs thousands per hour.

QSM15 — the 15-litre all-rounder

The QSM15 delivers up to 563 kW / 755 HP in peak ratings, with strong low-speed torque for loading cycles. It fits excavators, mining support trucks and prime power gensets.

Sourcing strategy for mining fleets

• Critical machines: new engines with full warranty and documented configuration.

• Support fleets & rebuilders: guaranteed used QSK19/QSM15 from original disassembly at a fraction of new price.

• Rotating spares: matched overhaul kits + turbochargers (HX55/HX82 class) + injectors in one consolidated shipment.
