Sinotruk ZZ5707S3840AJ 70 Ton Mine King Series Mining Truck: Unbeable Heavy-Duty Hauling & Ultimate Mine Productivity for Nigeria

Why the Sinotruk Mine King 70 Ton Mining Truck ZZ5707S3840AJ Is the Ultimate Choice for Nigerian Mining Operations

Nigeria’s mining sector is growing rapidly, with increased demand for high-capacity haulage solutions. The ZZ5707S3840AJ Mine King series is specifically designed for the harsh conditions of open-pit mining: steep ramps, rough haul roads, and high ambient temperatures. Its 70-ton payload capacity (up to 70 metric tons) allows you to move more material per cycle, reducing your cost per ton and increasing overall mine profitability. Fleet owners who have deployed the ZZ5707S3840AJ report haulage cost reductions of up to 25% compared to smaller 40-ton class trucks.

The truck’s robust frame is constructed from high-strength low-alloy steel with a box-section design, providing exceptional torsional rigidity and resistance to fatigue. The heavy-duty suspension system uses oil-nitrogen struts on the front axle and a walking beam design on the rear, ensuring excellent ride quality and tire life even on the roughest haul roads. The dump body is made from Hardox 450 wear-resistant steel with a liner option for highly abrasive materials.

Engineered for Extreme Mining Conditions

The ZZ5707S3840AJ is powered by a high-performance Sinotruk D12 or Cummins diesel engine, delivering up to 480 horsepower and 2,200 Nm of torque. This engine is designed for continuous heavy-load operation, with a heavy-duty cooling system capable of handling ambient temperatures up to 50°C. The transmission is an Allison 6-speed automatic or an Eaton manual 10-speed with a heavy-duty torque converter, providing smooth power delivery and reducing driveline shock. The rear axles are planetary type with a 40-ton capacity each, featuring fully floating shafts and a differential lock for maximum traction on slippery surfaces.

The braking system includes dual-circuit air brakes with drum brakes on all wheels, plus an exhaust brake and a hydraulic retarder option for descending long grades. This ensures safe operation even when carrying a full load down steep mine ramps. The tires are 21.00R33 or 24.00R35 radial mining tires, offering high load capacity and cut resistance.

Operator Comfort and Safety in a Rugged Environment

The Mine King cab is designed for operator safety and comfort during long shifts. The cabin is ROPS/FOPS certified (Roll Over Protection Structure / Falling Object Protection Structure), with a reinforced steel frame and laminated safety glass. The air-suspended driver seat is adjustable for weight and height, reducing fatigue. The cab is also equipped with air conditioning, a heating system, and sound insulation to keep noise levels below 80 dB. A digital display provides real-time data on engine parameters, payload, and diagnostic codes. For night operations, LED work lights are mounted on the cab and body.

Safety features include a backup alarm, rearview camera, and a tire pressure monitoring system (optional). The dump body is equipped with a safety prop and a remote camera for easy spotting. With the ZZ5707S3840AJ, your drivers can work efficiently and return home safely.
