This dump truck targets the mid-to-heavy tonnage segment of the mining transportation market, serving applications where reliability and payload efficiency are paramount considerations for project success.

Performance & Engineering

The heart of the LGMG MT86 mining dump truck lies in its powertrain configuration, centered around the WEICHAI WP13G530 engine—a 6-cylinder, 8+ liter displacement turbocharged diesel powerplant that achieves the critical balance between horsepower output and fuel efficiency. Generating 530 horsepower at optimal engine speeds, this powerplant delivers maximum torque exceeding 2500Nm, providing the necessary pulling force to maintain steady progress under full load conditions on inclined haul roads. The engine's robust construction incorporates heavy-duty internal components designed to withstand the sustained high-load cycles typical of mining applications, ensuring extended service intervals and reduced unplanned maintenance downtime. Compliant with Euro 3 emission standards, this powerplant meets regulatory requirements while delivering the performance characteristics mining operations require.

The FAST 8DS240C manual transmission paired with the WEICHAI engine features 10 forward gears and 2 reverse gears, enabling operators to precisely match gear ratios to varying haul road conditions and gradients. This wide gear spread optimizes fuel consumption during both loaded and empty return trips, while the robust synchronizer assemblies ensure smooth shifting even under the vibration and shock loads inherent in mining environments. The 6x4 drive configuration distributes engine torque effectively across six wheels equipped with 14.00R25 radial tires, providing exceptional traction on loose gravel, muddy surfaces, and steep inclines up to 34% gradient capability. The heavy-duty suspension system, featuring multi-leaf springs and heavy-duty shock absorbers, effectively cushions the chassis from road-induced stresses while maintaining stable handling during loaded operation.

Chassis engineering in the MT86 prioritizes structural integrity and load-carrying capacity, with the ladder-type frame constructed from high-strength alloy steel capable of withstanding the torsional stresses encountered during off-road operation. The 23-ton curb weight leaves substantial payload capacity within the 25-30 ton gross vehicle weight rating, enabling legal transport of 60-70 ton loads per trip cycle. The cargo box utilizes 5.9 x 3.2 x 1.5 meter internal dimensions yielding 26 cubic meters of volumetric capacity, with thick high-strength steel floors and walls featuring reinforced Rib-Design construction to resist abrasion from sharp aggregate materials and maintain structural integrity through thousands of loading cycles.
