Sandvik says it is upgrading its 30 t truck with the latest engine technology and adding TH430 to its Toro family.

This reliable, productive truck is now compliant with Stage V regulations, the most stringent emission regulations in the world. In addition to reducing emissions, the Stage V trucks can reduce fuel consumption by up to 3% compared with lower stage engines.

The Toro™ TH430 is a reliable, hard-working dump truck specifically designed for underground conditions, Sandvik says. With its robust structure, compact size and fit-for-purpose components, the truck is tailored to meet productivity targets in challenging environments.

High engine peak torque and torque rise allow less downshifting and better acceleration, while low overall machine weight and high power enable high tramming speeds on a decline, shortening cycle times. The Dana transmission’s automatic gear shift and torque converter lock-up ensure fast speeds, meanwhile.

The Toro TH430 truck has two engine configuration options: Stage V and Tier II/EU Stage II, both from Volvo Penta. Stage II has an output of 310 kW and Stage V has an output of 315 kW, making the Toro TH430 truck the most powerful underground truck in its size class, according to Sandvik.

In both configurations, the engine coolers are easy to clean and maintain, thanks to the swing-out fans. Designed for high ambient temperatures, the V-tube radiator has replaceable aluminium tubes for fast and easy repair. To help mines meet their targets to reduce fossil fuel consumption and exhaust emissions, both engine configurations can use renewable paraffinic diesel fuels that meet the EN 15940 standard, the company says.

The newly introduced engine option, the 13-litre Stage V engine, provides reduced emissions through a diesel particulate filter (DPF). Additionally, Sandvik Stage V trucks can operate with up to 3% less fuel consumption compared with lower stages. The other engine alternative, Tier 2/EU Stage II, is equipped with a catalytic purifier and muffler: it has been calibrated for use in high altitude conditions to maintain performance, low emissions and reliability.

To ensure maximum use of the rated payload on every trip, the Toro TH430 dump truck can be equipped with Sandvik’s Integrated Weighing System (IWS) for trucks. The IWS supports productivity by offering accurate real-time payload data for load and haul equipment operators. Using the IWS ensures full utilisation of the truck’s payload capacity on every cycle. Furthermore, using a 90% fill factor in the box selection ensures the truck can be loaded to its full 30-t capacity and reduces spillage during tramming. The smooth box design improves material flow during dumping, the company added.

“Sustainability is a key factor in all Sandvik designs,” Pia Sundberg, Product Line Manager Trucks at Sandvik, said. “Bringing the Toro TH430 truck with Stage V engine to the market takes mining one step further in its sustainability journey. We have also made several other improvements to the truck to make it even more reliable and productive.”
