Axle Configuration |
Heavy-duty 13-ton to 16-ton commercial axles, including BPW, FUWA, or equivalent configurable options, with oil-bath hubs and outboard brake drums for simplified maintenance. |
|
Kingpin Rating |
Interchangeable 2-inch (50 mm) or 3.5-inch (90 mm) forged steel kingpins, installed to standard SAE drop-in depths and secured with Grade 10.9 fasteners. |
|
Suspension Systems |
Mechanical heavy-duty multi-leaf spring suspension for high-durability off-highway stability, or trailing-arm air suspension with leveling valves for vibration-sensitive cargo. |
|
Payload Capacity |
Rated working load limits from 30,000 kg to 60,000 kg, depending on chassis girder section depth and axle configuration, including 2-axle, 3-axle, and multi-axle options. |
|
Dimensions |
Standard external lengths from 40 ft to 53 ft (12,192 mm to 16,154 mm), standard overall width of 2,550 mm, with variable fifth-wheel heights matched to tractor specifications. |
Inspection & Preparation
Chassis Alignment Test
Laser-guided tracking verification performed on every welded frame to prevent dog-tracking, uneven tire wear, and excessive rolling resistance.
01
Nondestructive Testing (NDT)
Ultrasonic and magnetic particle inspection applied to high-stress kingpin plate assemblies, landing gear brackets, and primary beam junctions.
02
Weld Seam Verification
Automated submerged arc welding (SAW) on primary I-beams followed by visual and dimensional checks to AWS D1.1 structural standards.
03
Surface Treatment
Shot-blasting to Sa 2.5 profile standards, followed by two-component anti-corrosive zinc-rich epoxy primer and polyurethane topcoat application.
04
Pneumatic & Electrical Testing
Full system pressure tests conducted on dual-line air brake circuits, ABS/EBS modules, and 24V LED lighting harnesses.
05
Applications
Intermodal Freight Logistics
High-frequency highway transport connecting distribution hubs, rail terminals, and maritime ports.
Construction & Heavy Machinery Transport
Hauling excavators, bulldozers, precast concrete components, and structural steel beams.
Bulk & Palletized Distribution
Transporting consumer goods, industrial raw materials, and temperature-controlled food supplies.
How to Choose the Right Semi-Trailer
Analyze Route and Axle Regulations
Verify local highway weight distribution laws (e.g., bridge formulas, axle-load limits) to determine whether a 2-axle, 3-axle, or spread-axle configuration is required.
Match Deck Height to Cargo Profile
Select flatbeds for standard loading docks, drop decks for height-restricted freight, or lowboys for self-loading heavy machinery.
Define Suspension Requirements
Specify air suspension for fragile cargo and frequent empty-return runs, or mechanical leaf springs for abrasive, unpaved job-site environments.
Calculate Operating Payload
Ensure the tare weight of the trailer combined with maximum cargo weight complies with national tractor-trailer gross combination weight rating (GCWR) limits.
