EXECUTIVE OVERVIEW: HOWO DUMP TRUCK 64 (HD-64)

Optimized for Mining, Construction & Bulk Logistics in Demanding Environments

The HOWO Dump Truck 64 (HD-64), manufactured by SINOTRUK and distributed globally by SEA LION International, represents a benchmark in heavy-duty off-highway transport for mining, large-scale construction, and bulk material logistics. Engineered for maximum payload efficiency (64-ton class) and operational resilience under extreme site conditions, the HD-64 delivers a demonstrable reduction in total cost of ownership (TCO) through its rugged powertrain, simplified maintenance architecture, and adaptability to region-specific fuel and terrain challenges. This model is not merely a transport solution but a productivity multiplier in environments where downtime equates to critical project delays.

Core Application Advantages

• Mining: Excels in overburden removal and ore haulage on unpaved, steep-grade mine roads. Reinforced chassis (U-shaped 320mm high-strength steel frame), 6×4/8×4 configurations, and aggressive tire options ensure stability on loose surfaces. Hydraulic retarder integration significantly reduces brake wear during sustained descents.
• Construction: Ideal for large earthmoving projects (dams, highways, urban infrastructure) requiring high-cycle dumping. Fast-cycle hoist system (≤18s dump time), reinforced tailgate latching, and optimized body geometry (18-22m³ standard) maximize daily material throughput.
• Logistics: Dominates in bulk aggregate, coal, and sand transport over secondary roads. Fuel-efficient MAN-technology WD615 series engine (Euro III/IV compliant) coupled with 10-12 speed transmissions provides reliable long-haul capability where infrastructure is variable.
