Sandvik has upgraded its 30-metric-ton Toro TH430 truck with a Stage V engine by Volvo Penta. The underground truck can reduce fuel consumption by up to 3% compared to units with lower-stage engines, the company reported.

The engine has an output of 315 kW, making the truck the most powerful in its size class, Sandvik said. It can use paraffinic diesel fuels that meet the EN 15940 standard. A diesel particulate filter cuts emissions.

With swing-out fans, the engine coolers are easy to clean and maintain. Designed for high ambient temperatures, the V-tube radiator has replaceable aluminum tubes for fast and easy repair.

The Toro TH430 is designed to meet productivity targets in challenging environments. High-engine peak torque and torque rise allow less downshifting and better acceleration, Sandvik said. Low overall machine weight and high power enable high tramming speeds on a decline and shortened cycle times. The Dana transmission’s automatic gear shift and torque converter lockup ensure fast speeds.

The truck is equipped with Sandvik’s Integrated Weighing System, which gives real-time payload data and can help ensure utilization of the truck’s payload capacity on every cycle. Using a 90% fill factor in the box selection means the truck can be loaded to its full 30-mt capacity and reduces spillage during tramming. The smooth box design improves material flow during dumping.
