Brief Introduction
SINOTRUK HOWO 400HP 8×4 Heavy-duty Front-four-rear-eight Dump Truck, High-payload Mining & Construction Engineering Tipper
Product Description
Powerful & stable power system for heavy-duty dump truck operations This HOWO 8×4 400hp front-four-rear-eight dump truck adopts MAN-tech MC11 engine with large displacement, delivering peak torque 1900N·m at low RPM. It provides strong power for full-load dump starting and steep mine climbing. Equipped with original dedicated PTO for dump trucks, it supplies stable oil pressure to the dump hydraulic lifting system, enabling smooth, fast lifting during high-frequency mass material dumping without power attenuation. The built-in WEVB exhaust brake greatly reduces brake pad wear during downhill dumping, improving driving safety for long-distance heavy dump hauling and lowering maintenance frequency of the dump truck brake system.
Core Functions
This export-grade ultra-heavy dump truck is built based on mature SINOTRUK HOWO heavy-duty vehicle platform, specially optimized for overloaded mining and large-scale earthwork transportation. Different from medium-load 6×4 dumpers, the 8×4 front-four-rear-eight chassis realizes balanced load distribution, breaking payload limitation of traditional engineering transport vehicles. It integrates heavy-load material hauling, high-frequency hydraulic unloading and downhill auxiliary braking functions, realizing high-profit one-stop bulk material transportation.
Matched with MAN-tech localized MC11 high-efficiency engine and original supporting hydraulic accessories, the whole vehicle achieves coordinated power and unloading performance. Reinforced bearing structure greatly resists impact deformation during dumping, cutting fleet downtime and operational loss. With complete export certification and mature overseas after-sales network, it is a high-profit flagship model for large mining groups and infrastructure contractors.
Product Core Functions & Advantages
1. Reliable Heavy-duty Power Output
Powerful & stable power system for heavy-duty dump truck operations This HOWO 8×4 400hp front-four-rear-eight dump truck adopts MAN-tech MC11 engine with large displacement, delivering peak torque 1900N·m at low RPM. It provides strong power for full-load dump starting and steep mine climbing.

The built-in WEVB exhaust brake greatly reduces brake pad wear during downhill dumping, improving driving safety for long-distance heavy dump hauling and lowering maintenance frequency of the dump truck brake system.
2. Super-high Legal Payload to Boost Revenue
Higher load capacity raises profit per dump trip The
8×4 Dump Truck has a legal 31-ton GVW and much larger rated payload than 6×4 rear eight-wheel dump trucks, transporting more materials per dump trip to boost revenue. Dual front steering axles share weight from the dump truck cab and front dump box for even load distribution.
3. Reinforced Chassis Structure for Long Service Life
The 300mm double thick high-strength frame, 16-ton heavy-duty planetary axles and 12 reinforced rear leaf springs strongly resist deformation and cracking caused by dump lifting impact and bumpy full-load dump travel, extending the dump truck service life and cutting downtime & operation costs for dump work.
4. Outstanding Off-road Adaptability for Harsh Sites
Standard inter-axle and wheel differential locks prevent slipping and trapping on muddy mine dump sites to maintain high dump attendance rate.

2. Working Principle
The full operating system of HOWO 400HP 8×4 dump truck consists of five linkage modules: reinforced chassis bearing system, MAN-tech MC11 power system, dual front steering axle load-sharing system, hydraulic unloading system and WEVB auxiliary braking system.
During full-load transportation, the large-displacement MC11 engine outputs stable 1900N·m peak torque at low RPM, realizing effortless startup and steep-slope climbing under heavy cargo load. The dual front steering axles share front-end vehicle gravity, disperse overall stress to avoid local chassis overload. The 16-ton planetary rear axles matched with standard dual differential locks distribute driving power evenly, locking slipping wheels instantly on muddy dump sites to prevent vehicle trapping.
When executing unloading operations, the original dump-dedicated PTO independently outputs power to hydraulic components, maintaining constant hydraulic oil pressure. It supports continuous, high-frequency dumping actions, ensuring fast and steady cargo box lifting without power attenuation. During long-distance downhill transportation, the built-in WEVB exhaust brake assists speed control, sharing braking load of main brake pads, reducing thermal fading risk of brake system.
The 300mm thickened frame and 12 reinforced rear leaf springs buffer instantaneous impact force generated by hydraulic lifting and bumpy road vibration, disperse structural stress, effectively avoid chassis cracking and component fatigue damage, and guarantee long-term overloaded and high-frequency cyclic operation stability.
3. Daily Application Scenarios
Large-scale Open-pit Mining: Mine ore bulk haulage, quarry rock and aggregate transportation, coal mine residue clearance and material turnover
Heavy Earthwork Projects: Large-area land reclamation, road foundation filling, river regulation earthwork transportation
Super Infrastructure Construction: Expressway expansion, high-speed railway foundation works, large-scale water conservancy projects
Harbor Bulk Cargo Handling: Port ore stacking transfer, wharf ballast transportation, heavy bulk cargo short-distance turnover
High-intensity Overseas Engineering Bidding: Large mining projects, heavy infrastructure bidding in Africa, Central Asia and Southeast Asia, suitable for high-load and high-frequency working conditions
4. Comparison with Traditional Vehicles
Vs 6×4 Rear Eight-wheel Dump Trucks: Traditional 6×4 dumpers have limited legal GVW and small single-trip payload, low daily output and profit margin. This 8×4 model owns 31-ton legal GVW, larger loading capacity to raise per-trip revenue. Dual front axles optimize load distribution, solving front-end overload and chassis cracking defects of 6×4 vehicles under heavy load.
Vs Ordinary 400HP Engineering Trucks: Common
400HP Dump Trucks lack professional exhaust auxiliary brake, causing severe brake pad wear during downhill haulage and frequent brake failure. Equipped with original WEVB exhaust brake, this HOWO model cuts brake maintenance cost greatly and improves driving safety.
Vs Non-original PTO Modified Dumpers: Refitted universal PTO leads to unstable hydraulic pressure, easy lifting jamming and power attenuation during continuous dumping. The factory-original dedicated PTO matches MC11 power system perfectly, sustaining stable hydraulic output for long-time high-frequency dumping.
Vs Light-duty Reinforced Chassis Vehicles: Ordinary reinforced frames cannot bear instantaneous impact of heavy-load dumping, easy to deform and crack. Adopting 300mm double thick frame plus thickened leaf springs, this vehicle has stronger anti-fatigue performance, lower downtime and comprehensive operation cost.
