Front Loading Detachable Gooseneck Lowbed Trailer
The Front Loading Detachable Gooseneck Lowbed Trailer (also known as a hydraulic removable gooseneck lowboy) is a premier heavy-haul semi-trailer engineered for safe, front-loading access of ultra-heavy, self-propelled construction machinery and industrial equipment. Featuring a 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 hydraulic detachable gooseneck mechanism allows the entire front neck to disconnect, enabling equipment to drive directly onto the ultra-low deck (300–600 mm clear loading height) from the front without heavy ramps. This minimizes loading risks, ensures absolute stability, and complies with strict highway overhead bridge clearance limits. Fully certified under ECE, ISO9001, CCC, CE, DOT, and SGS standards.

Key Structural & Performance Features
1. Hydraulic Detachable Gooseneck (RGN) Mechanism for Front Loading
- Hydraulic Disconnection System: Features dual heavy-duty hydraulic cylinders that separate the gooseneck from the main deck, allowing the trailer front to lower completely to the ground for direct front-on loading.
- High-Tensile Steel Frame: Fabricated with Q345B, Q550, Q700, or T700 steel plates to withstand extreme dynamic loading stresses during the re-attachment and lifting cycle.
- Automated SAW Welding: Robotic Submerged-Arc Welding (SAW) combined with $CO_2$ gas-shielded welding guarantees exceptional frame durability and joint integrity.
- Ultra-Low Deck Well: Provides a sunken deck height of 300 mm to 600 mm, maximizing vertical clearance for tall excavators, loaders, and crawler cranes.
2. 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 low-profile 6.75-17.5 or 9.00-22.5 steel rims.
- Suspension Options: Multi-leaf heavy-duty spring suspension or shock-absorbing air/hydraulic suspension system.
- Braking System: Dual-line ABS anti-lock braking system (WABCO, Kemi, Haldex, or equivalent) for secure stopping performance under full load.
3. Front Loading & Cargo Securing Setup
- Ramp-Free Front Drive-On: Eliminates the need for rear loading ramps, allowing low-clearance crawler machines and rollers to drive straight onto the deck safely.
- Platform Width Extension: Outriggers and side brackets extend platform width by 250–300 mm per side to accommodate wide industrial machinery.
- Cargo Securing Systems: GR120 heavy-duty lashing chains, D-ring anchor points, and wheel chocks to lock cargo firmly against displacement.
- Standard Accessories: Integrated hydraulic power pack or tractor PTO connection, 28-Ton two-speed landing gear, 50# (2") or 90# (3.5") kingpins, 24V 7-pin LED lighting system, and a lockable tool box.
Commercial & Logistics Terms
- Warranty Policy: 3-Year warranty for the main beam; 1-Year warranty for axles and hydraulic cylinders.
- Delivery Lead Time: 30 – 40 working days upon order confirmation.
- 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).
