To increase productivity, improve reliability and reduce truck operating costs, Sandvik has introduced a new transmission for its flag ship trucks Sandvik TH551i and Sandvik TH663i. The new size-class transmission is a result of extensive product development work done by Sandvik and the transmission supplier to meet the cus-tomer needs for 51 and 63 tonnes trucks.
In the new transmission, improved reliability and reduced costs are achieved with robust and simple design, made specifically for heavy off-road application. Compared to the previous model, the transmission lifetime is expected to be longer, and less gearbox change-outs are required during the truck lifetime, reducing total costs.
From the intelligence point of view, self-diagnostics in the transmission control system has been improved and fully integrated into the Sandvik Intelligent Control System, enabling easy and fast trouble shooting without external diagnostics tools or laptops.
The driveline design has been also improved as a the original two-piece rear driveline shaft is replaced with a one-piece driveline shaft. This more robust driveline shaft extends the driveline lifetime, eases maintenance and eliminates the need for the rear driveline support bearing.
The Upgrade solution can include also a new durable and maintenance friendly aluminium cooler with outstand-ing corrosion resistance and long component lifetimes (option).
Front and rear axles replacement is mandatory in down-hill loaded applications.
