A key characteristic of general liquid transportation is the wide variety of cargo types and fluctuating freight demand.
The HCH9402GPG tank body is manufactured from high-strength quality carbon steel. Its smooth inner surface undergoes strict anti-corrosion and rust-prevention treatment, allowing it to transport various non-hazardous liquid materials, including:
Industrial oil products: Lubricating oil, base oil, heat transfer oil, hydraulic oil, and other petroleum-based products
General chemical products: Non-corrosive industrial additives, processing agents, water treatment chemicals, and similar materials
Daily-use products: Food-grade configurations are available for transporting edible oil, syrup, and other food raw materials
The ability to handle multiple types of liquids enables operators to accept a wider range of cargo orders, reduce empty return trips, and improve vehicle utilization and monthly operating mileage.
3) Lightweight Structure Optimization for Higher Payload Efficiency
Under the current transportation environment where both axle-based charging and weight-based charging systems are applied, every 100 kg reduction in vehicle weight allows an additional 100 kg of cargo to be transported per trip, creating significant long-term economic benefits.
The lightweight version of the HCH9402GPG has a curb weight as low as 7,800 kg, placing it among the leading models in the same-volume three-axle general liquid tank trailer category.
Its lightweight design is not achieved through simple material reduction. Instead, it is realized through structural optimization, high-strength material application, and integrated accessory design.
The tank body adopts an equal-strength structure, with reinforced materials used in key stress areas while unnecessary weight is reduced in non-load-bearing sections. The chassis features an optimized gooseneck structure with a lower front and higher rear layout, improving center-of-gravity distribution while maximizing material efficiency.
4) Comprehensive Safety Design for Controlled Transportation
The core safety concerns in liquid transportation are preventing liquid movement, leakage, and rollover risks. The HCH9402GPG addresses these challenges through a complete safety protection system covering three key areas.
Inside the tank, multiple anti-surge baffles divide the large-capacity tank into interconnected compartments. This design effectively reduces liquid surge during acceleration, braking, and turning, minimizing the impact of liquid movement on vehicle stability. It provides significantly improved driving stability, especially on mountain roads and during emergency braking situations.
The trailer uses fully automated longitudinal and circumferential welding processes to ensure uniform and high-quality weld formation. After welding, the tank undergoes hydraulic pressure and airtightness testing to eliminate leakage risks.
Key sealing components, including manholes and discharge outlets, use mature sealing structures with oil-resistant and aging-resistant seals, ensuring long-term reliability.
For road handling safety, the three-axle suspension system provides balanced load distribution. Leaf spring suspension options are available with different configurations, and the braking system is equipped with an EBS anti-lock braking system.
5) Precision Manufacturing Quality for Extended Service Life
Changhua Automotive holds dual qualifications for special equipment design and manufacturing and has obtained ISO9001 quality management system certification. All products follow standardized manufacturing procedures.
The HCH9402GPG tank body uses genuine national-standard steel materials. Every production stage, including cutting, forming, welding, painting, and final assembly, is controlled through dedicated quality inspection checkpoints.
The exterior of the tank adopts professional anti-corrosion coating technology with multiple layers of primer and topcoat protection, helping resist corrosion caused by rain, snow, salt, alkaline environments, and chemical dust.
The chassis and accessories also receive anti-rust treatment. Under normal maintenance conditions, the trailer can achieve a service life exceeding the industry average.
For transportation companies that value long-term vehicle residual value, reliable manufacturing quality means lower annual depreciation costs throughout the vehicle lifecycle.
