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 rail 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%.
High-rail Protection & Safe Reliable: Adopts double-layer/triple-layer high-rail structure design, rail height optional 800-1800mm, column spacing encrypted to 500-600mm, equipped with high-strength crossbars and diagonal braces for reinforcement, forming a three-dimensional protection frame, effectively preventing cargo displacement and falling during transportation; rail panels adopt stamping corrugated plate/square tube welding structure, strong impact resistance, and can withstand bulk cargo stacking pressure and bumps on complex roads.
Ventilated & Fresh-keeping Adaptation: Open high-rail structure has excellent ventilation, air circulation rate increased by 40%, suitable for transportation of vegetables, fruits, livestock and poultry that require fresh-keeping/ventilation, reducing cargo mildew and spoilage loss; optional detachable tarpaulin frame and waterproof tarpaulin, realizing free switching between rainproof and sun protection, balancing ventilation and protection needs.
Multi-directional Loading & Unloading · Efficient Convenient: Supports multi-directional loading and unloading from the side, rear and top (hoisting), combined with openable side rail panels (4-6 opening options) and rear opposite-opening doors, adapting to various loading and unloading equipment such as forklifts and loaders, loading and unloading efficiency 50% higher than traditional box-type carriages; rail panels are equipped with high-strength rope tighteners (8-12 per side) and cargo fixing hooks, facilitating quick cargo fixation, which can be completed by one person.
Compliant Heavy-load & Stable Structure: 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". When the total mass ＞3.5 tons, multi-layer non-detachable laminates (evenly distributed) are standard. Blue-card light truck models meet the requirements of load quality coefficient and size limits; integrated welding of frame and rail frame, bottom plate selects 3.0-5.0mm anti-slip steel plate/aluminum alloy pattern plate, key parts are fixed by robot welding + high-strength rivets, service life up to 15-20 years (traditional ordinary steel high-rail carriages are about 8-12 years).

Core Process Advantages

Integrated High-rail Structure Design: Optimize the force structure of columns and crossbars through ANSYS finite element analysis, reduce stress concentration, rail panel deformation ≤2mm/m; columns adopt thickened square tubes (50×50×3mm/60×60×3mm), the bottom is rigidly connected to the frame, improving overall torsional rigidity, suitable for heavy-load and large-sized cargo transportation.
Precision Manufacturing & Anti-corrosion Treatment: Key structures adopt CNC cutting and bending processes, with dimensional accuracy up to ±1mm, and the splicing gap of rail panels 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, and not easy to fade after long-term outdoor use.
Full-process Quality Control: Raw materials undergo material spectral analysis and tensile strength testing; the production process real-time monitors welding quality, rail panel flatness and structural stability; finished products pass load test, impact resistance test and cargo fixation reliability test. Complete test reports are provided for each batch with traceable quality.

Application Scenarios

Fresh Agricultural Product Transportation: Cross-regional transportation of vegetables, fruits, fresh agricultural products, etc. Good ventilation reduces loss, and tarpaulin can be used for rain and sun protection.
Bulk Cargo Transportation: Transportation of bulk materials such as grain, feed, coal and sand. High-rail protection prevents leakage, and multi-directional loading and unloading improves efficiency.
Large-sized/Package Cargo Transportation: Transportation of large-sized goods such as pipes, plates, agricultural machinery and equipment, furniture. Rail panels can be opened in sections, facilitating fixation and loading/unloading.
Livestock and Poultry Transportation: Transportation of live pigs, cattle, sheep and other livestock. High-rail structure has good ventilation, and rail height and spacing can be customized to adapt to the living space of livestock and poultry.
New Energy Supporting: Special high-rail carriages for pure electric/hydrogen energy trucks, lightweight design improves cruising range, suitable for urban distribution and short-distance fresh agricultural product transportation scenarios.

Typical Application Cases

Fresh Agricultural Product Transportation - 6.8m Steel-aluminum Composite High-rail Carriage: Customized 6.8m steel-aluminum composite high-rail carriage for a fresh agricultural product logistics enterprise, adopting Q355 steel frame + aluminum alloy rail panels, weight only 2.7 tons (traditional all-steel carriage is about 4.1 tons), double-layer high-rail + detachable tarpaulin frame, excellent ventilation. The loss rate of vegetables and fruits transportation is reduced by 6%, and the annual fuel cost is saved by about 29,000 yuan.
Heavy-load Bulk Cargo Transportation - 9.6m All-steel High-rail Carriage: Supplied 9.6m all-steel high-rail carriage for a coal trading company, bottom plate thickness 4.0mm, triple-layer high-rail structure, column spacing 550mm, equipped with 12 high-strength rope tighteners, load capacity up to 25 tons, cumulative transportation mileage exceeding 1.2 million km without structural deformation.
New Energy Urban Distribution - 4.2m All-aluminum High-rail Carriage: Customized 4.2m all-aluminum high-rail carriage, adapted to new energy light truck chassis, weight only 1.2 tons, load ratio increased by 13%, cruising range up to 220km, 4 openable side rail panels + hydraulic tailgate, used for community group buying fresh food distribution. The daily operating cost is 60% lower than that of the fuel version, and it has been put into batch use in first-tier cities.
