TRUCK: Liebherr introduces new 100-t T 236 to select markets

GERMANY – Liebherr recently introduced a new mining truck, the 100-tonne T 236 that offers increased productivity, better efficiency, enhanced reliability, and improved safety. And the cost of transporting a tonne of rock is now lower.

This is the first machine to feature the company’s vertically integrated electric drive system, the Liebherr Litronic Plus Generation 2 technology.

According to Liebherr, “with its high take off torque and continuous power to ground capability, the T 236 is less sensitive to grade and payload variations, providing mining customers with class leading productivity.”

“The T 236 is the first diesel electric truck in its class to incorporate an oil immersed braking system with four corner retarding capabilities, providing reliable braking technology.”

It is designed to carry up to 100 tonnes, and complements the R 9100, R 9150, R 9200, and R 9250 excavators.

The machine uses advanced active front end technology, using electrical energy during retarding events so that the drive system can deliver controlled engine speed with almost no fuel consumption.

It is equipped with a double pole battery, starter motor, and hoist system as standard, and provides an innovative drive system inhibitor, with each plug and drive power module electrically interlocked to grounding devices.

The truck operates on a voltage of 690 VAC and 900 V DC, while the machine’s Litronic Plus isolation system ensures the safety of maintenance personnel through the elimination of hazards by design.

The T 236’s in-line electrical power train layout minimises cable length, while the maintenance free IP 68-rated plug and drive power modules ensure continual operation in harsh environments.

It features an ergonomic cab and quality front wheel suspension systems for a smoother drive in comfort.

The first prototypes are undergoing “intensive field functional and performance testing,” Liebherr said. The vehicles are not yet commercially available, although pre-series T 236 units will be available for select markets.
