Liebherr Completes Field Tests for T236 Hauler

At an international press event recently in Leoben, Austria, Liebherr showcased its T 236 mining truck. This 100-metric-ton (mt) haul truck, which is powered by a diesel-electric drive system, is the first in this class with a four-corner, oil immersed braking system. Since its debut at MINExpo 2016 in Las Vegas, the T 236 has successfully completed its testing phase and has recently started its first field operation trials at the Erzberg iron mine in Austria.
Capitalizing on decades of experience in off-highway truck technologies, the T 236 takes advantage of Liebherr’s electric- drive system innovations with the vertically integrated Litronic Plus Generation 2 AC drive system.
An industry first, Liebherr’s Litronic Plus Isolation system ensures the safety of maintenance personnel through the elimination of hazards by design. To ensure safety, the T 236 is equipped with double-pole battery, starter motor and hoist system isolators as standard. Each plug and drive power module are electrically interlocked to grounding devices. Operating on a voltage level of 690 VAC and 900 VDC enables regular site technicians to carry out system maintenance.
The revolutionary in-line electrical power train layout minimizes cable length, while the maintenance-free IP 68-rated plug-and-drive power modules ensure reliable operation in all-weather situations. Combined with the extended life service intervals and minimized maintenance time offered by the ground-level service points, the T 236 ensures maximum uptime.
The ergonomic T 236 cab and the superior properties of the front-wheel suspension system promotes driver efficiency with comfort, safety, acceleration and handling for improved performance.
The next evolution in Electric Drive System design, Liebherr’s Litronic Plus Generation 2 drive system introduces advanced Active Front End technology. Making efficient use of electrical energy during retarding events, the drive system controls engine speed with almost no fuel consumption. A variable-speed hydraulic system reduces parasitic losses to provide maximum power, while lowering fuel consumption when power is not required.
With its high takeoff torque and continuous power to ground capability, the T 236 is less sensitive to grade and payload variations.
