Chevron’s Delo TorqForce MP has been approved by Allison Transmission as the first, and currently only, lubricant to meet the new TES 781 specification for stationary off-highway transmissions. TES 781 targets high-load, continuous-duty services such as hydraulic fracturing and high-pressure pumping, where transmissions run at sustained torque and temperature for long intervals. For mine operators using Allison-powered fixed or skid-mounted equipment, the approval provides a defined fluid option for warranty compliance and for managing wear, varnish and unplanned downtime in severe-duty drivetrains.

BHP’s Western Australian Iron Ore (WAIO) haul truck fleet is delivering about 127,000 t/month (1.52 Mt/y) of additional iron ore after an engineering upgrade developed with JC Hydraulic. The solution centres on modified hydraulic tipping systems on ultra-class haul trucks, enabling faster, more reliable dump cycles and reducing truck idle time at crushers and stockpiles. For mine planners and maintenance teams, the change effectively adds high-availability truck capacity without expanding fleet size, with revenue uplift estimated in the tens of millions of dollars per year.

Lundin Mining’s 70%-owned Caserones copper mine in Chile has become the first active operation to run an ultra-class haul truck with a hybrid-electric system, retrofitting Komatsu 930E truck #330 with a Cummins First Mode kit. The retrofit converts the diesel-electric truck to a hybrid configuration using an onboard energy storage system to capture and reuse braking energy on haul cycles. For mine planners and maintenance teams, the project provides an in-field reference for fuel burn reduction, potential payload-neutral decarbonisation, and integration of hybrid powertrains into existing 930E fleets.
