contracts awarded today have a fuel cap. Previously, “wet contracts” had no limit on fuel and contractors were not so concerned by the fuel efficiency of their machines. Today, mining contractors are being forced to rank fuel consumption high up on their buying checklists. With a range of fuel-saving innovations, the T236 will surely address these woes. Lower cost per ton Abie Kriel, technical manager – Mining at Liebherr Africa, says the T236 sets a new era by becoming the first truck in the 100 t segment to utilise a diesel-electric drive system. A major talking point is Liebherr’s Litronic Plus Generation 2 drive system, which introduces the advanced Active Front End technology. Making use of electrical energy during retarding events, the drive system is able to deliver controlled engine speed, controlled decent speeds via speed control and active braking. “The Active Front End control and electric drive work in harmony to use less fuel and cause less wear on components, translating into greater cost-savings,” says Kriel. “As the first diesel-electric truck in the 100 t class to incorporate an oil immersed braking system with four-corner braking control, the T236 is geared to deliver sound reliability and performance, even in tough operating conditions.” Christopher Vorster, national sales manager – Mining at Liebherr Africa, says with its high take-off torque and continuous power-to-ground capability, the T236 is less sensitive to grade and payload variations, resulting in greater productivity. Vertical integration of Liebherr designed and manufactured components ensures that the truck’s powertrain achieves optimal system efficiency and performance throughout the full range of applications. The truck’s innovative, variable hydraulic system lowers machine parasitic losses to provide maximum power, while lowering fuel consumption when power is not required. “Powered by a Cummins QST30-C engine, the T236 reduces fuel consumption due to its low parasitic powertrain losses. Optimised energy consumption during propulsion ensures the Liebherr T236 makes efficient use of constant engine power, providing the lowest possible fuel consumption,” explains Vorster. “Efficiency is a key ingredient for a successful mining operation. This truck enables customers to enjoy unrivalled performance while

Liebherr Africa intends to deploy the truck to work at a leading Northern Cape mine.

QUICK TAKE

The first Liebherr T236 rigid hauler has arrived in South Africa as part of the pre-series units being rolled out to selected operations across the world to further validate the truck’s capabilities before its commercial launch

100 metric tonne

Designed to carry up to 100 metric tonne payload, the T236 can be ideally paired with Liebherr’s R 9100, R 9150, R 92 00 or R 9250 mining excavators

The T 236 is said to be the first truck with a diesel electric configuration in this size class

The T236 is the first diesel-electric truck to incorporate an oil immersed braking system with four-corner retarding capabilities, thereby providing reliable braking capability
