General Specifications of 8×4 Drive Dump Truck

1. Model Classification by Application Scenario

Urban Muck Removal Model: Optimized for narrow urban roads (≤5m width) and municipal dust control. Focuses on "compact size + environmental compliance" (e.g., closed cargo cover, low noise) to meet urban management requirements.

Infrastructure Long-Haul Model: Designed for inter-regional transport of construction aggregates (gravel, sand) on highways/national roads. Prioritizes "high load capacity + fuel efficiency" for 100–300km daily trips.

Port Bulk Handling Model: Tailored for port-to-warehouse transfer of coal, ore, and bulk commodities. Features "corrosion resistance + fast unloading" to adapt to high-humidity port environments and frequent cargo turnover.

Product Overview

The 8×4 Drive Dump Truck is a heavy-duty paved-road transport vehicle engineered for "high load efficiency + urban/infrastructure/port adaptation"-solving pain points of traditional 6×4 dump trucks (insufficient payload) and 6×6 off-road models (poor fuel efficiency on highways). Its core value lies in **four key strengths**: 8×4 rear-dual-drive configuration (stable on paved roads, fuel-saving vs. full-wheel drive), large payload (25–40 tons), scenario-tailored designs (closed covers for cities, wear-resistant boxes for infrastructure, anti-corrosion parts for ports), and global compliance (China National VI, EU Stage V, US Tier 4 Final). Equipped with a high-efficiency hydraulic dumping system (38°–45° tipping angle) and paved-road-optimized chassis (low rolling resistance tires, air suspension optional), it reduces transport costs by 15% and maintenance frequency by 20% vs. generic dump trucks. It is the first choice for global trade clients requiring reliable, high-volume bulk transport on highways, urban roads, and port yards.

Product Details

1. 8×4 Drive Dump Truck: Scenario-Specific Customized Models

The 8×4 Drive Dump Truck offers three dedicated models to match distinct paved-road application needs, avoiding one-size-fits-all inefficiencies. The Urban Muck Removal 8×4 Drive Dump Truck (25–30 tons payload, 8.5–9.8m overall length) is optimized for narrow city roads (≤5m width): it features an IPX5 waterproof electric rolling cargo cover (full closure in 60 seconds, meeting municipal dust regulations) and a low-noise engine (≤78dB at idle, avoiding residential complaints). Its short wheelbase (3.2+1.3+1.3m) ensures maneuverability in crowded construction sites, and the Q690 steel cargo box (8mm bottom, 6mm sides) resists wear from urban muck. The Infrastructure Long-Haul 8×4 Drive Dump Truck (30–35 tons payload, 9.2–10.5m overall length) targets inter-regional gravel/sand transport: it uses NM450 wear-resistant steel (10–12mm bottom, 8mm sides) for sharp aggregates, a 12-speed ZF AMT transmission (reducing driver fatigue on 100–300km daily trips), and Michelin X MultiWay 3D low-rolling-resistance tires (saving 5% fuel vs. standard tires). The Port Bulk Handling 8×4 Drive Dump Truck (35–40 tons payload, 9.5–10.8m overall length) adapts to high-humidity port environments: it has optional 304 stainless steel cargo box parts (salt spray resistance ≥2,000 hours) to prevent corrosion from seawater, 4 parallel Bosch Rexroth hydraulic cylinders (fast tipping for frequent port turnover), and a hydraulic retarder (reducing brake wear during port yard start-stops).

2. 8×4 Drive Dump Truck: High-Capacity Cargo Box & Hydraulic Dumping System

The 8×4 Drive Dump Truck's cargo box and hydraulic system are designed for large-volume, efficient unloading on paved roads. Cargo box volumes are scenario-matched: 18–22 m³ (urban, for daily muck removal), 25–28 m³ (infrastructure, for long-haul gravel), and 28–30 m³ (port, for bulk coal/ore). All boxes have a shot-blasted inner surface (Ra ≤2.0μm) to reduce wet material residue to ≤0.8%-eliminating manual cleaning time. The hydraulic dumping system is tailored to payloads: urban/infrastructure models use 2 Hengli HSG110 double-acting cylinders (18–22 MPa working pressure), tipping to 38°–42° in 35–40 seconds; port models use 4 parallel cylinders (22 MPa pressure), tipping to 45° in 40–45 seconds (ensuring complete unloading of dense iron ore). A pressure relief valve prevents overload damage, and a gravity buffer lowering function reduces chassis impact by 35%-extending frame life to 8+ years. The system is controlled via a cab-mounted electric panel (real-time tipping angle display, ±0.5° accuracy) with an emergency manual valve-critical for power failures in remote infrastructure sites.

3. 8×4 Drive Dump Truck: Paved-Road-Optimized Power & Chassis System

The 8×4 Drive Dump Truck's power and chassis balance heavy-load performance and paved-road efficiency-avoiding the fuel waste of off-road models. Engines are selected for scenario needs: urban models use 280–320 hp Yuchai YC6JA320-60 (1200–1400 N·m torque, low noise for cities); infrastructure models use 350–400 hp Cummins ISD4.5s5350 (1500–1700 N·m torque, 220 g/kWh fuel efficiency); port models use 400–450 hp Weichai WP12.460E62 (1800–2000 N·m torque, high torque for frequent loading). The chassis uses a 4-axle configuration (1 steering axle + 3 rear axles, 2 drive axles): front axles (9-ton FAW Dana) ensure steering stability, while rear drive axles (16-ton Sinotruk HW169) handle heavy loads. Suspension systems are optimized: urban/infrastructure models use 10-leaf mechanical leaf springs (cost-effective for paved roads); port models offer optional WABCO ECAS air suspension (reducing vibration by 40% for fragile processed ore). Tires are 12R22.5 radial types: Bridgestone M729 (port, wear-resistant) and Michelin X MultiWay 3D (infrastructure, fuel-saving)-all with a service life ≥100,000km on paved roads.

4. 8×4 Drive Dump Truck: Comprehensive Safety & Environmental Features

The 8×4 Drive Dump Truck integrates safety devices and environmental technologies to meet global regulations and urban/port requirements. Safety protections include: ROPS/FOPS-certified cabs (ISO 3471/3449) to shield drivers from falling objects (port/construction sites); 360° surround-view cameras (urban/port models) + 0.5–5m reversing radars-avoiding collisions with pedestrians in crowded cities or port containers. The braking system uses dual-circuit air brakes + ABS (ECE R13) + optional EBS (EU/US markets)-shortening braking distance by 25% on wet highways. Urban models add lane departure warning (LDW) to prevent fatigue-related lane drifts on long urban ring roads. For environmental compliance, all models meet China National VI, EU Stage V, and US Tier 4 Final emissions-equipped with DPF (particulate matter reduction 90%) and SCR (NOₓ reduction 90%). Urban models use low-VOC paint (EU REACH compliant) to reduce air pollution, while port models have anti-leakage oil pans (preventing seawater contamination from oil spills).

5. 8×4 Drive Dump Truck: Operational Efficiency & Global After-Sales Support

The 8×4 Drive Dump Truck is designed for low downtime and easy global maintenance-critical for trade clients. Operational efficiency features include: centralized lubrication systems (infrastructure/port models) that auto-grease chassis components (extending maintenance intervals to 15,000km, reducing downtime by 30%); 10-inch cab touchscreens (supporting navigation, fuel monitoring, and fault diagnosis) to streamline operations. Cab comfort is enhanced for long shifts: air suspension seats, dual-zone air conditioning, and USB charging ports-reducing driver fatigue during 8+ hour hauls. For global trade, certification support covers CE (EU), DOT (US), CCC (China), and SABS (South Africa)-with full technical documents (material test reports, emission certificates) for customs clearance. After-sales service includes: 24-month warranty on engines/axles, 18-month warranty on hydraulic cylinders, and 40+ global service centers (Germany, China, Brazil, US) providing on-site repairs. Spare parts kits (brake pads, cylinder seals, tire valves) are delivered within 72 hours, and free operator training (hydraulic system maintenance, safe dumping) is offered to minimize human error.

This English product introduction fully highlights the 8×4 Drive Dump Truck's unique "paved-road efficiency + scenario customization" advantages and avoids repetition with off-road dump trucks (e.g., 6×6) or smaller models. It can be directly used for platform listing. If you need to add niche details (e.g., cold-region anti-freeze systems for northern EU/US), adjust regional certifications (e.g., Australia ADR, India BIS), or emphasize cost-saving benefits for small logistics firms, feel free to let me know for further optimization.
