• Diversified Materials & On-demand Adaptation: Optional all-steel structure (Q235/Q355 high-strength steel), steel-aluminum composite structure (steel frame + aluminum alloy side panels), all-aluminum structure (6061-T6/5083-H111) to meet different load and cost requirements. All-steel structure has tensile strength ≥345MPa, suitable for 30-ton-class heavy-load transportation; steel-aluminum composite structure reduces weight by 20%-30%, balancing bearing capacity and fuel economy; all-aluminum structure reduces weight by 35%-45%, saves 15%-25% of fuel costs annually, and increases the cruising range of new energy vehicles by 20%-30%.​
• Side-opening Design & Efficient Loading/Unloading: Adopts single-side/double-side side-door structure (2-6 doors optional), side doors can be opened at 90°-180°, supporting forklift side loading/unloading. Combined with rear opposite-opening doors, it realizes dual-direction loading/unloading without dead ends, and the loading/unloading efficiency is 50% higher than that of traditional fixed carriages; side doors are equipped with high-strength hinges and locking mechanisms, which are easy to open and firmly locked, and can be easily operated by one person, suitable for high-frequency loading/unloading scenarios such as logistics parks and warehouses.​
• Heavy-load Stability & Structural Optimization: Integrated design of frame and carriage, crossbeam spacing encrypted to 500-600mm, bottom plate selects 2.5-4mm anti-slip steel plate/aluminum alloy plate, load-bearing capacity increased by 30%; side door frames are reinforced with thickened square tubes, key parts are fixed by robot welding + high-strength rivets, with excellent torsional rigidity, which can withstand lateral cargo impact and bumps on complex roads; the surface is treated with electrophoretic coating/anodizing, salt spray corrosion resistant, service life up to 15-20 years (traditional ordinary steel carriages are about 8-12 years).​
• Compliant Safety & Full-scenario Adaptation: Strictly follow standards such as GB 7258 "Safety Technical Conditions for Motor Vehicle Operation" and GB/T 23336 "Tank Vehicles for Transporting Dangerous Goods in Liquid Form by Road". Side doors are equipped with anti-drop pins, reflective signs and safety warning lights. Blue-card light truck models meet the requirements of load quality coefficient and size limits; optional side door anti-collision strips and anti-cargo drop baffles further improve transportation safety, suitable for multi-scenarios such as urban distribution and medium-long-distance transportation.​
• Flexible Customization & Function Expansion: Can be customized in size (length 3-14m, width 2.2-2.6m, height 2.0-3.2m), supporting different side door layouts such as 2 doors on single side, 4 doors on single side, and opposite opening on double sides; optional accessories such as hydraulic assist for side doors, electric opening, tarpaulin frame, toolbox, hydraulic tailgate, adapting to transportation needs of package goods, bulk goods, fruits and vegetables, building materials, etc., and personalized configurations meet diverse operation scenarios.​

Core Process Advantages​

 

• Integrated Side-opening Structure Design: Optimize the connection structure between side doors and frame through ANSYS finite element analysis, reduce stress concentration, and the number of side door opening times can reach more than 100,000 times without failure; the sealing performance between side doors and carriage is excellent, equipped with multi-layer wear-resistant sealing strips, reaching IP66 dustproof and waterproof level, effectively protecting goods from external environmental impacts.​
• Precision Manufacturing & Anti-corrosion Treatment: Key structures adopt CNC cutting and bending processes, with dimensional accuracy up to ±1mm, and the closing gap of side doors is uniformly ≤3mm; all-steel models undergo triple anti-corrosion of pickling phosphating + electrophoresis + powder coating, no rust after 1000 hours of salt spray test; aluminum models undergo anodizing + electrophoretic coating, simultaneously improving corrosion resistance and appearance.​
• Full-process Quality Control: Raw materials undergo material spectral analysis and tensile strength testing; the production process real-time monitors welding quality, side door opening flexibility and locking reliability; finished products pass load test, side door fatigue opening test and sealing performance test. Complete test reports are provided for each batch with traceable quality.​

Application Scenarios​

 

• Logistics Distribution: Transportation of package goods such as supermarket general merchandise, e-commerce parcels, furniture and home appliances. Side loading/unloading is adapted to warehouse platforms, improving sorting efficiency.​
• Fruit and Vegetable Transportation: Transportation of agricultural products such as vegetables and fruits. The opening of side doors facilitates ventilation and heat dissipation, and the tarpaulin frame can be used for rain and sun protection, reducing cargo loss.​
• Building Materials Transportation: Transportation of building materials such as pipes, plates and ceramic tiles. Side loading/unloading can avoid cargo damage caused by dragging, and fixing with rope tighteners is more stable.​
• Bulk Cargo Transportation: Transportation of bulk materials such as grain, feed and coal. Side doors can be opened in sections, facilitating partial unloading and cargo inventory.​
• New Energy Supporting: Special side-door carriages for pure electric/hydrogen energy trucks, suitable for high-frequency loading/unloading scenarios such as urban short-distance distribution and community group buying.​

Typical Application Cases

 

• Logistics Distribution - 6.8m Double-side Door Steel-aluminum Composite Carriage: Customized 6.8m double-side door carriage for a large logistics company, adopting Q355 steel frame + aluminum alloy side panels, weight only 2.6 tons (traditional all-steel carriage is about 4.0 tons), 4 side doors on each side + rear opposite-opening doors, adapting to forklift side loading/unloading. The daily average loading/unloading efficiency is increased by 60%, and the annual labor cost is saved by about 35,000 yuan.​
• Fruit and Vegetable Transportation - 9.6m Single-side 4-door All-steel Carriage: Supplied 9.6m side-door carriage for a fruit and vegetable trading company, all-steel heavy-load structure, bottom plate thickness 3.5mm, side doors can be opened in sections, equipped with ventilation windows and detachable tarpaulin frame, suitable for cross-regional fruit and vegetable transportation. The cargo loss rate is reduced by 8%, and the cumulative transportation mileage exceeds 1 million km without failure.​
• New Energy Urban Distribution - 4.2m Double-side Opposite-opening All-aluminum Carriage: Customized 4.2m all-aluminum side-door carriage, adapted to new energy light truck chassis, weight only 1.3 tons, load ratio increased by 15%, cruising range up to 230km, double-side opposite-opening design combined with hydraulic tailgate, suitable for high-frequency loading/unloading of community group buying. The daily operating cost is 65% lower than that of the fuel version, and it has been put into batch use in first-tier cities.​

Quality Assurance​

 

• Test Reports: Provide raw material quality reports, carriage dimensional accuracy test reports, load test reports, side door fatigue opening test reports, sealing performance test reports, salt spray corrosion test reports, etc.​
• After-sales Commitment: For non-human damage, the carriage warranty is 5 years (core structure warranty 10 years), and vulnerable parts such as side door hinges and locking mechanisms are warranted for 2 years; provide free installation and commissioning guidance, regular maintenance plans, and lifelong parts replacement and old carriage renovation services.
• Quality Standards: Strictly follow industry standards such as GB 7258 "Safety Technical Conditions for Motor Vehicle Operation", GB/T 23336 "Tank Vehicles for Transporting Dangerous Goods in Liquid Form by Road", GB/T 18411 "Road Vehicle Product Labels".​
