Standard Configuration
1. Heavy Load Main Frame
- Main beams use Q345B/T700 high-strength wear-resistant manganese steel, built as an integrated six-longitudinal through beam with fully automatic submerged arc welding.
- Detachable gooseneck fitted; its transition zone connecting to the cargo deck adopts triple-layer thickened reinforcing plates.
- Load zone reinforced H cross beams with T-slot load-bearing layout.
- Standard 4mm anti-wear patterned steel floor, plus extra ribs on high-stress spots. It withstands concentrated heavy machinery impacts and avoids floor sagging, cracks or weld separation, rated for 80–120 ton extreme heavy haulage.
2. Axles & Suspension
Standard five 13-ton reinforced heavy axles; 16-ton axles available as upgrade. FUWA, BPW, SAF premium brand axles are optional.
The axle hubs of the 5-axle heavy-duty low-bed semi-trailer feature a durable, maintenance-free design capable of meeting the demands of continuous, high-intensity operations.
Factory-fit heavy mechanical balanced suspension evenly shares load across all five axles, cutting single-axle pressure and adapting to mountain gradients, rugged job-site roads and gravel ground.
Air or hydraulic suspension upgrades deliver superior shock absorption to safeguard delicate heavy machinery.
3. Tyres & Rims
- Standard 20 units of 11.00R20 / 12R22.5 heavy-duty tubeless tyres with thick carcass. Crush, tear and heat resistant with low blowout risk for heavy loads.
- Matching thick high-strength steel wheels with great heat dissipation, ideal for long low-speed heavy transport.
- Optional extras: low-profile tyres, run-flat heavy tyres and lightweight forged aluminum rims for weight saving without losing load capacity.
4. Towing & Stabilizing Support
- Fitted with heavy forged 90# / 50# JOST kingpins. Detachable gooseneck works with multiple towing connections for firm, impact-resistant coupling on bumpy roads and heavy pull-offs.
- 40-ton high-strength hydraulic landing legs deliver double the load capacity of standard supports. Synchronized smooth lifting/lifting holds the trailer steady during heavy-load parking, gooseneck assembly/disassembly and long-term stationary storage.
5. Loading & Unloading Spring Ramps
- Standard heavy ramps made of thick manganese steel with reinforced brackets and load pins; single ramp load capacity exceeds 70 tons.
- Spring assist enables easy opening and stable rebound, allowing self-loading/unloading of all medium-to-large construction machines without extra lifting gear, cutting logistics costs and speeding up work.
- Anti-slip grating and side guard plates can be added on request.
6. Brake & Electrical Systems
- WABCO dual-line air brake system with standard ABS. Multi-axle synchronized braking evenly spreads brake force to prevent weak stopping and skidding on steep downhill heavy hauls, and syncs braking with tractors.
- Full 24V universal wiring harness, dual 7-pin & 15-pin waterproof connectors, bright extended LED rear lamps, side marker lights and full-circle reflective markings.
- Complies with domestic and EU oversize haul standards, reliable for cross-border night transport.

Core Product Advantages
1. Balanced Axle Load & Higher Load Capacity
The 5-axle heavy-duty low-bed semi-trailer features a load-equalizing structure with 5 axles and 20 tires, along with six reinforced main beams, effectively reducing the load per axle. It has a rated payload of 60 tons and a maximum heavy-load transport capacity of 120 tons; compared to 3-axle or 4-axle low-bed semi-trailers, it offers over 40% greater load-bearing strength, making it capable of handling demanding, ultra-heavy transport tasks.
2. Ultra-Low Recessed Deck for Oversized Cargo
Detachable gooseneck + sunken deck cuts loading height for tall machinery and wind power parts. Removable gooseneck enables flexible direct loading/unloading of oversize freight.
3. Optional Steering Axle for Better Maneuver & Safety
Optional rear follow-up steering shortens turning radius, easy to pass narrow sites and mountain bends. Synchronized multi-axle brakes ensure stable downhill stops, avoiding rollover and tail swing risks.
4. Versatile for All Heavy Haul Scenarios
Standard heavy ramps fit self-propelled construction equipment; recessed deck carries heavy machinery, wind components and large steelwork. Detachable gooseneck supports hoisting and self-loading, reducing trailer idle time.
5. Tough Build, Low Maintenance & High Resale Value
Full thick high-strength steel with reinforced key parts resists impact, fatigue and corrosion for longer service life. Universal spare parts and maintenance-free axles cut repair downtime. Good residual value brings higher long-term ROI.
