100-Ton Hauler Saves Fuel, Nixes Maintenance Hazards

Liebherr recently unveiled the new 100- metric-ton (mt) T 236 mining truck, which features the vertically integrated Litronic Plus Generation 2 alternating current (AC) drive system, and is optimally paired with the company’s R 9100, R 9150, R 9200 or R 9250 mining excavators. Empty vehicle weight is 80 mt. Horsepower (hp) is 895 kilowatts (kW). Maximum speed is 55 kilometers per hour (km/h). It is designed to meet Tier 2 standards. Drive system components include Active Front End technology. Capturing electrical energy during retarding events, the drive system delivers controlled engine speed with almost no fuel consumption, the company reported. The variable hydraulic system lowers parasitic energy usage to provide maximum power and lower fuel consumption.

The T 236 features a double pole battery, starter motor and hoist system isolators as standard. In addition, the truck provides an innovative drive system inhibit, electrically interlocked to grounding devices for each plug and drive power module. It operates on 690 volts AC (VAC) and 900 volts direct current (VDC), and site technicians conduct system maintenance. Liebherr’s Litronic Plus Isolation system, through the elimination of hazards by design, ensures the safety of maintenance personnel. The in-line electrical power train layout minimizes cable length. Maintenance- free IP 68-rated plug and drive power modules ensure reliable operation in all-weather situations, the company reported. The truck uses an oil immersed braking system with four corner retarding capabilities. Liebeherr said the truck is currently not commercially available, but pre-series units will be released in select markets.
