Mobile Crane Transport Lowbed Semi-Trailer
The Mobile Crane Transport Lowbed Semi-Trailer is a specialized heavy-duty transport trailer engineered for hauling rough-terrain cranes, all-terrain cranes, truck cranes, counterweights, and boom sections. With a payload capacity ranging from 30 to 150 tons, it is fabricated from Q345B/Q550/Q700/T700 high-tensile steel using automated submerged-arc welding. Its ultra-low loading deck (700–1,100 mm) paired with reinforced low-incline loading ramps easily accommodates multi-axle mobile cranes and long boom overhangs, providing optimal axle load distribution, bridge clearance compliance, and maximum driving stability during transport. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Dedicated Heavy-Duty Frame for Mobile Cranes & Counterweights
- High-Tensile Steel Construction: Fabricated with Q345B, Q550, Q700, or T700 steel to withstand concentrated axle loads from heavy crane chassis and dense iron counterweights.
- Automated SAW Welding: Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees superior structural endurance under heavy road shock and vibration.
- Reinforced Main Beams: Main beam height options of 450 mm, 500 mm, or 520 mm with extra-thick top and bottom flange plates.
- Anti-Skid Checkered Platform: 4 mm, 5 mm, or 6 mm checkered steel floor provides high surface traction for heavy rubber-tired cranes and boom cradles.
2. Axle, Suspension & Braking Systems
- Axle Configurations: 2 to 6 axles (Supports FUWA, BPW, Huajin, or equivalent premium brands; 13T / 16T / 20T / 25T capacity per axle).
- Tire & Rim Setup: 8 to 24 heavy-duty tires paired with 6.75-17.5 or 9.00-22.5 high-load steel rims.
- Suspension Options: Heavy-duty multi-leaf spring suspension (10/12 leaves) or shock-absorbing air suspension system.
- Braking System: Dual-line ABS anti-lock braking system (WABCO, Kemi, Haldex, or equivalent).
3. Crane-Specific Loading & Cargo Securing Setup
- Extended Low-Angle Ramps: Heavy-duty mechanical, hydraulic, or spring-assisted ramps with shallow incline angles to prevent long mobile crane chassis and boom overhangs from grounding out.
- Gooseneck Configurations: Fixed, detachable (front-loading), hydraulic, or foldable gooseneck designs for flexible loading scenarios.
- Width Extension: Outriggers/side brackets extend platform width by 250–300 mm per side to fit wide-body all-terrain cranes.
- Cargo Securing Systems: GR120 heavy-duty lashing chains, heavy wheel chocks, and ratchet binders to secure crane outriggers and counterweights firmly.
- Standard Accessories: 28-Ton two-speed landing gear (JOST / FUWA), 50# (2") or 90# (3.5") interchangeable kingpins, 24V 7-pin LED lighting system, 1–2 spare tire carriers, and a waterproof tool box.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for the main beam; 1-Year warranty for axles.
- Delivery Lead Time: 25 – 35 working days upon order placement.
- Packaging & Shipping: Nude packing; shipped via Ro-Ro vessel, Bulk Cargo ship, or Container.
- Payment Terms: T/T (Telegraphic Transfer), L/C (Letter of Credit).
