Core Product Features

Diversified Materials & On-demand Adaptation: Optional all-steel structure (Q235/Q355 high-strength steel), steel-aluminum composite structure (steel frame + aluminum alloy box panels), all-aluminum structure (6061-T6/5083-H111) to meet different load and scenario requirements. All-steel structure has tensile strength ≥345MPa, suitable for 25-ton-class heavy-load transportation; steel-aluminum composite structure reduces weight by 20%-25%, balancing bearing capacity and fuel economy; all-aluminum structure reduces weight by 35%-40%, saves 12%-20% of fuel costs annually, and increases the cruising range of new energy vehicles by 18%-28%.
Fully Enclosed Sealing & Enhanced Protection: Adopts integrally formed fully enclosed box structure, with multi-layer wear-resistant sealing strips at the joints between the box body and doors, reaching IP67 dustproof and waterproof level, effectively blocking the intrusion of rainwater, dust and moisture, and protecting goods from external environmental impacts; optional insulation layer (PU polyurethane/rock wool) with thermal conductivity ≤0.024W/(m·K), suitable for pre-cooled goods transportation, with heat preservation time ≥6 hours after power failure.
Safe Load-bearing & Stable Structure: Integrated welding design of frame and box body, crossbeam spacing encrypted to 450-550mm, bottom plate selects 3.0-5.0mm anti-slip steel plate/aluminum alloy pattern plate, load-bearing capacity increased by 25%; box body frame is reinforced with thickened square tubes, top is equipped with anti-deformation crossbeams, key parts are fixed by robot welding + high-strength bolts, with excellent torsional rigidity, which can withstand bumps on complex roads and cargo stacking pressure, service life up to 15-20 years (traditional ordinary steel box-type carriages are about 8-12 years).
Flexible Door Opening & Efficient Loading/Unloading: Supports customization of multiple door opening methods, including rear opposite-opening doors (opening angle 180°/270°), single-side/double-side side doors (2-4 doors optional), top-hinged doors, realizing efficient loading/unloading with forklifts and loading platforms; doors are equipped with high-strength hinges and anti-theft locking mechanisms, which are easy to open and firmly locked, and can be easily operated by one person, suitable for multi-scenario loading/unloading needs such as logistics parks, warehouses and communities.
Compliant Adaptation & Function Expansion: 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", equipped with reflective signs and safety warning lights. Blue-card light truck models meet the requirements of load quality coefficient and size limits; can be customized in size (length 3-14m, width 2.2-2.6m, height 2.0-3.8m), optional accessories such as hydraulic tailgate, electric tarpaulin, ventilation windows, anti-theft alarm devices, internal fixed shelves, meeting diverse transportation needs.

Core Process Advantages

Integrated Sealed Structure Design: Optimize the force structure of the box body through ANSYS finite element analysis, reduce stress concentration, and the deformation of the box body ≤3mm/m; the box body adopts CNC bending + integral welding process, no splicing gaps, further improving the sealing performance and structural stability, avoiding goods being damp and damaged during transportation.
Precision Manufacturing & Anti-corrosion Treatment: Key structures adopt CNC cutting and laser welding processes, with dimensional accuracy up to ±1mm, and the closing gap of doors is uniformly ≤2mm; all-steel models undergo triple anti-corrosion of pickling phosphating + electrophoresis + powder coating, no rust after 1200 hours of salt spray test; aluminum models undergo anodizing + electrophoretic coating, simultaneously improving corrosion resistance and appearance, and not easy to fade after long-term use.
Full-process Quality Control: Raw materials undergo material spectral analysis and tensile strength testing; the production process real-time monitors welding quality, sealing performance and dimensional accuracy; finished products pass load test, sealed waterproof test and impact resistance test. Complete test reports are provided for each batch with traceable quality.

Application Scenarios

Urban Distribution: Short-distance transportation of supermarket general merchandise, e-commerce parcels, fresh ingredients, etc. The fully enclosed structure is rainproof and dustproof, adapting to urban road restriction requirements.
Long-distance Transportation: Medium and long-distance transportation of furniture, home appliances, precision equipment, packaged goods, etc. It has strong sealing and protection, reducing cargo transportation loss.
Special Goods Transportation: Transportation of pre-cooled food, medical supplies (non-temperature-controlled), electronic components and other goods requiring dust and moisture protection, optional insulation and anti-theft configurations.
Dangerous Goods Transportation (Compliant Modification): After special modification, it can be adapted to the transportation of ordinary dangerous goods (such as packaged chemical raw materials, fireworks and firecrackers), equipped with explosion-proof door locks and ventilation devices, meeting the compliance requirements of dangerous goods transportation.
New Energy Supporting: Special box-type carriages for pure electric/hydrogen energy trucks, suitable for urban green distribution, community group buying and other scenarios, lightweight design improves cruising range.

Typical Application Cases

E-commerce Logistics - 6.8m Double-side Door Steel-aluminum Composite Box-type Carriage: Customized 6.8m double-side door carriage for a large e-commerce logistics company, adopting Q355 steel frame + aluminum alloy box panels, weight only 2.9 tons (traditional all-steel carriage is about 4.3 tons), 2 side doors on each side + rear opposite-opening doors, adapting to forklift side loading/unloading. The daily average loading/unloading efficiency is increased by 50%, and the annual labor cost is saved by about 32,000 yuan.
Precision Equipment Transportation - 9.6m All-steel Sealed Box-type Carriage: Supplied 9.6m box-type carriage for an equipment manufacturing enterprise, all-steel heavy-load structure, bottom plate thickness 4.0mm, internal equipped with anti-slip rubber pads and fixed shelves, box body sealing level IP67, suitable for cross-regional transportation of precision instruments, with a cumulative transportation mileage of over 900,000km without goods damage records.
