Sandvik has upgraded its Toro TH320 20-t and Toro TH330 (pictured) 30-t trucks to, it says, reduce customers’ costs of ownership and improve productivity.
With a hardy structure, compact size and fit-for-purpose components, the trucks are built to be robust and reliable and tailored to meet productivity targets in challenging underground environments, according to the company.
Both upgraded trucks come with a 235 kW Tier 3 Volvo Penta engine with catalytic purifier and muffler, delivering long engine lifetime in underground mining conditions. The 8 litre engine has a high-tech injection system that contributes to an efficient combustion and low fuel consumption, Sandvik says. Furthermore, it is calibrated for use in high-altitude conditions without sacrificing performance or reliability.
The heavy-duty and efficient aluminium cooler has “outstanding” corrosion resistance and is easy to clean, helping to reduce total cost of ownership, Sandvik says. To minimise brake and transmission overheating and brake wear as well as to provide better control of downhill speed, the trucks can be equipped with an optional engine brake.
Sandvik has equipped the trucks with new heavy-duty axles using limited slip differential to maintain traction, which are expected to have an extended lifetime compared with the previous models.
“We have really worked to improve availability and reliability and reduce the time needed for servicing or maintenance,” Pia Sundberg, Product Line Manager, Trucks, at Sandvik Mining and Rock Solutions, says. “For fast ramp speeds when hauling ore, we have equipped these trucks with a new transmission with automatic gear shifting and torque converter lock-up.”
To increase uptime, Sandvik has also made upgrades to enable easy and fast maintenance. The trucks are designed for daily ground-level maintenance. When accessing the top of the equipment is required, the entirely new access system on the front of the truck provides a steady grip, including three-point contact high-contrast handles and anti-slip steps. The proven hydraulic system of the truck is simple and reliable, contributing to ease of maintenance and lower total cost of ownership.
