Crawler Crane Lowbed Semi-Trailer
The Crawler Crane Lowbed Semi-Trailer is an extra-heavy-duty transport semi-trailer custom-engineered for hauling crawler crane bodies, track shoes, boom sections, and heavy counterweight systems. Built with a rated load capacity ranging from 30 to 150 tons, it is constructed using Q345B/Q550/Q700/T700 high-tensile steel and automated submerged-arc welding. Its ultra-low loading deck (700–1,100 mm) combined with heavy-duty low-incline ramps provides maximum lateral stability, prevents tipping during drive-on loading, and ensures bridge clearance compliance when moving massive tracked crane equipment. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Reinforced Heavy-Duty Frame for Tracked Crane Components
- High-Tensile Steel Construction: Fabricated with Q345B, Q550, Q700, or T700 steel plates, engineered specifically to absorb severe point-load concentrations from heavy crawler tracks and dense counterweights.
- Automated SAW Welding: Robotic Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees maximum structural endurance against high vibration and torsion.
- Heavy Main Beam Profile: 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 plate floor with heavy-duty traction ridges to prevent steel track shoes from slipping during drive-on loading.
2. Heavy-Duty Axle, Suspension & Braking Systems
- Axle Configurations: 2 to 6 axles (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: Multi-leaf heavy-duty 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. Crawler Crane Loading & Cargo Securing Setup
- Gooseneck Configurations: Fixed, detachable (front-loading), hydraulic, or foldable gooseneck designs for flexible loading scenarios.
- Extended Low-Angle Ramps: Mechanical, hydraulic, or spring-assisted ramps built with low climb angles to support high-tonnage crawler equipment.
- Width Extension: Side outriggers/brackets extend platform width by 250–300 mm per side to accommodate wide crawler track bases.
- Cargo Securing Systems: GR120 heavy-duty lashing chains and ratchet binders ensure zero-displacement tie-down for heavy crane bodies and boom sections.
- Standard Accessories: 28-Ton two-speed landing gear (JOST / FUWA), 50# (2") or 90# (3.5") interchangeable kingpins, 24V 7-pin LED light kit, 1–2 spare tire carriers, and a lockable 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).
