Overview

Sinotruk Howo-7 6×4 Dump Truck: A Heavy-Duty Workhorse for Construction and Mining

The Sinotruk Howo-7 6×4 Dump Truck is a robust and reliable heavy-duty vehicle engineered to tackle the most demanding construction, mining, and earthmoving tasks. As one of SINOTRUK’s flagship models, it combines exceptional power, durability, and advanced features to deliver unmatched performance in challenging working conditions, particularly in emerging markets like Africa where it holds leading market share.

Engine: Weichai WD615 series 336-371HP diesel engine, renowned for high reliability, strong power, and low fuel consumption
Transmission: HW19710 10-speed manual gearbox (SINOTRUK’s own HOWO series), ensuring smooth shifting and durable performance
Drive Configuration: 6×4 (three axles, four driving wheels) with robust 16-ton rear axles and 5.73 ratio for heavy-load hauling
Payload Capacity: 21-30 tons, with a spacious 18.63 m³ cargo box (5400x2300x1500mm)
Cabin: European-inspired HOWO classic cab with single berth, air conditioning, and left-hand drive, designed for operator comfort during long shifts

Powerful and Adaptable Engine: The Weichai diesel engine delivers high torque at low RPMs, ensuring excellent performance even on steep gradients and uneven surfaces. Its strong fuel adaptability makes it ideal for operating in regions with variable fuel quality.
Robust Chassis and Axles: Built with heavy-duty components, the Howo-7’s chassis and axles are designed to withstand extreme loads and harsh operating conditions, minimizing downtime and maintenance costs.
Efficient Hydraulic System: The ventral lift hydraulic system provides smooth and reliable cargo unloading, reducing cycle times and improving productivity on job sites.

Function

MC Series Engine – SINOTRUK's Exclusive High-End Power

Experience more power with less fuel: Employing the most advanced BOSCH high-pressure common rail system, the ECU precisely controls the fuel injection process according to the engine’s operating state, achieving a maximum injection pressure of 1600 bar to ensure superior fuel atomization, increased engine power, and reduced fuel consumption. Durable and Reliable: The cylinder block is constructed from vermicular graphite cast iron, offering increased rigidity and strength, enabling thinner walls, and reducing engine weight. Compared to traditional gray cast iron, vermicular graphite cast iron offers a 75% increase in tensile strength, a 40% increase in elastic modulus, and a 100% increase in fatigue strength.

Axles - Carry More, Cost Less

The MC series drive axles and V series steering axles are engineered based on advanced German axle technology and improved with the latest technical standards, offering higher transmission efficiency, superior heat dissipation, increased load capacity, and extended service life to accommodate various road conditions. The main reducer utilizes an Oerlikon gear, offering a 10% increase in strength and improved transmission efficiency
