HOWO 371HP 6×4 Water Tank Truck

Introduction

In an era where operational efficiency defines municipal resilience and construction productivity, reliable large-volume water transport is no longer optional—it’s foundational. The HOWO 371HP 6×4 Water Tank Truck delivers unmatched dependability for dust control, road cleaning, emergency response, and rural water distribution—turning logistical challenges into seamless, high-yield operations.

Company Overview

ZW Group is a certified China water truck supplier with over 15 years of focused expertise in HOWO specialized vehicles. We engineer, manufacture, and export heavy duty water trucks—including HOWO water bowser, road cleaning water truck, and construction water tanker models—to more than 40 countries across Africa, the Middle East, Southeast Asia, and Latin America. Our commitment extends beyond delivery: with ISO-certified production, localized technical support, and globally stocked spare parts, ZW Group ensures uptime, not just arrival.

Product Introduction

Built on the proven Sinotruk HOWO ZZ1257M4647C 6×4 chassis, this diesel water tank truck integrates rugged mobility with precision liquid handling. Its 20,000-liter Q235 carbon steel tank features internal anti-corrosion coating and full-welded structural reinforcement. Equipped with a front spray bar, rear sprinkler system, and 360° rotatable high-pressure water cannon (≥28m horizontal range), it supports multi-mode operation—from gentle irrigation to aggressive dust suppression—without reconfiguration.

Key Features

• High-strength Q235A carbon steel tank with sandblasting + epoxy anti-corrosion treatment
• Self-priming, high-flow centrifugal water pump (120 m³/h @ 1.0 MPa)
• Triple-function spray system: front V-type nozzle (for road cleaning), rear dual-side sprinklers (for wide-area coverage), and adjustable high-lift cannon (for vertical reach up to 32m)
• HW76 cab with ergonomic controls, air suspension seat, and sleeper berth for extended shifts
• 6×4 drive configuration ensuring superior traction on unpaved roads, slopes, and wet surfaces

Technical Specifications

Applications

• Municipal water truck: street sweeping, sidewalk rinsing, public space sanitation
• Road construction water tanker: sub-base compaction, asphalt cooling, dust mitigation
• Agricultural & landscape irrigation: orchard watering, nursery maintenance, greenbelt replenishment
• Emergency water supply: disaster relief, remote community resupply, mining site hydration
• Industrial site management: quarry misting, landfill leachate control, concrete batching plant support

Performance and Value

With its optimized weight distribution, low center of gravity, and torque-rich powertrain, the HOWO 371HP water tank truck reduces fuel consumption by up to 12% compared to legacy models under identical load cycles. The corrosion-resistant tank design extends service life beyond 12 years—even in saline or alkaline environments—while modular spray components enable rapid field repairs. This translates directly into lower TCO (Total Cost of Ownership), higher fleet utilization, and measurable ROI within 18 months of deployment.

Quality and Support

Every HOWO water bowser undergoes 100% non-destructive weld inspection, hydraulic pressure testing at 1.5× working pressure (1.5 MPa), and full-system functional validation. ZW Group maintains regional technical hubs in Nairobi, Dubai, and Bogotá, offering remote diagnostics, on-site operator training, and guaranteed 72-hour spare parts dispatch for priority markets.

Why Choose HOWO

HOWO is the most widely deployed Chinese heavy-duty chassis platform for specialized water applications—accounting for over 65% of exported municipal water trucks from China since 2020. Its mature engineering, global parts interoperability, and documented performance in extreme climates make it the benchmark for reliability in emerging infrastructure markets.

Factory and Shipment

Manufactured in Sinotruk’s Tier-1 certified facility, each unit receives three-stage painting: zinc phosphate pretreatment → epoxy primer → polyurethane topcoat (UV- and abrasion-resistant). Units are secured on marine-grade wooden cradles, wrapped in waterproof PE film, and shipped via container or Ro-Ro vessel with full cargo insurance and customs documentation support.

Conclusion

Engineered for endurance, validated in real-world conditions, and backed by a global support ecosystem—the HOWO 371HP 6×4 Water Tank Truck is engineered not just to carry water, but to empower progress.
