Straight-Beam Truck-Mounted Crane Semi-Trailer

Jinfeng China Straight-Beam Truck-Mounted Crane Semi-Trailer is an integrated high-efficiency engineering transport solution, purpose-built for lifting, transporting, and loading heavy cargo such as construction materials, machinery, and steel products.

The trailer features a high-strength straight beam frame formed from premium low-alloy steel, offering exceptional load capacity and torsion resistance for long-term heavy-duty use on complex roads. It pairs with a customized hydraulic crane, whose hexagonal high-strength steel boom ensures flexible extension, stable lifting, and customizable tonnage and boom lengths to meet diverse lifting needs from short to long-distance operations.

The cargo box adopts a single-side opening wing van design, allowing the side panel to be opened hydraulically to form a wide loading channel, enabling direct side loading/unloading with forklifts or pallets for maximum loading/unloading convenience. Optional waterproof and dustproof seals protect cargo while maintaining operational efficiency. The modular design supports customization of cranes, outriggers, and box structures to match various chassis and working conditions.

Safety Precautions

1. Always park the trailer on solid, flat ground before lifting. Extend all outriggers with support pads and never overload or lift at an angle to ensure even force distribution.

2. Check for personnel or obstacles around the box before opening/closing the wing panels. Follow hydraulic operation guidelines strictly to avoid structural impact from rapid movement.

3. Reset and lock the crane, and fully close and secure the wing van before driving to prevent component movement or detachment during transit.

4. Never stand under the crane boom during lifting. Keep the load steady, avoid sudden stops or turns, and refrain from lifting in severe weather like strong winds or heavy rain.

Usage & Maintenance

1. Before daily use, check the crane’s hydraulic oil level, outrigger cylinder seals, and wing van hydraulic lines for leaks, and verify brakes and lights function properly.

2. Regularly apply grease to the crane’s slewing bearing and boom rails, test hydraulic system pressure, and replace worn seals to prevent system failures.

3. Clean and repaint rust spots on the frame and box regularly, inspect welds for cracks, and focus maintenance on critical load-bearing points like crane mounts and outrigger connections.

4. Replace hydraulic and engine oil per the manual, keep maintenance records, and store the trailer in a dry, ventilated area with the crane retracted and outriggers stowed to prevent corrosion.
