Lightweight Low-Deck Flatbed Semi-Trailer

The China Jinfeng Lightweight Low-Deck Flatbed Semi-Trailer is a professional vehicle specially built for the transportation of construction machinery, large equipment and heavy cargo. The whole vehicle adopts a high-low deck structure: the front gooseneck section has a higher load platform, while the rear deck steps down lower, forming a Z-shaped frame layout with front-high and rear-low sections, which flexibly accommodates cargo of different heights and specifications. The vehicle is widely applicable to the transportation of construction machinery such as excavators, loaders and road rollers, as well as the long-distance transit of heavy cargo such as steel, pipe piles and large equipment. With excellent loading adaptability, stability and economy, it is trusted by domestic and overseas customers and serves as a reliable partner in the heavy-cargo transportation sector. The overall length, wheelbase, side rails and deck dimensions can all be flexibly customized according to customers' transportation needs, meeting personalized loading solutions. Jinfeng has many years of experience in manufacturing special-purpose vehicles, with whole-process quality control, and provides complete after-sales support and spare parts services, ensuring customers can purchase with confidence and use with peace of mind.

Product Advantages

1. Lightweight Design: By adopting high-strength materials and structural topology optimization, the vehicle weight is significantly reduced without sacrificing strength or load capacity. Under the same number of axles, more cargo can be loaded, increasing the transport capacity per trip while reducing fuel consumption and toll costs, significantly lowering long-term operating costs.

2. High-Low Deck Structure: With the stepped loading platform in a front-high, rear-low configuration, the rear deck is lower and the center of gravity of the whole vehicle is lower, ensuring more stable driving and higher safety at high speed and during cornering. Loading and unloading of oversized cargo is more convenient, and the high and low deck areas can be flexibly selected according to cargo height, expanding the loading range.

3. Strong Load Capacity: With a continuous main beam and reinforced crossbeam design, and the frame verified by finite element analysis, the load is evenly distributed, and both uniform and concentrated loads perform excellently, capable of handling the transportation of heavy cargo and large equipment with ease.

4. Convenient Loading and Unloading: A reasonable platform height and flat loading surface facilitate quick operation by forklifts and cranes, greatly shortening loading and unloading time, improving overall transport efficiency and reducing waiting time and site costs. Optional hydraulic ramps, lashing rings and other accessories make operation even more convenient.

5. Durable and Reliable: The whole vehicle adopts electro-coating anti-corrosion treatment, and the frame is resistant to corrosion and fatigue, adapting to various complex road conditions, with a long service life, low maintenance cost and high return on investment.

Material Introduction

The main beam of the frame uses Q355B high-strength low-alloy structural steel, which features high yield strength and good toughness, effectively achieving lightweight while ensuring load capacity. The side beams and crossbeams adopt high-strength section steel, optimizing the overall load distribution with outstanding torsional performance. The gooseneck section adopts a thickened box structure with stronger torsional and bending resistance, and the connection parts have smooth transitions and small stress concentration. The load floor adopts wear-resistant chequered steel plate, which is anti-slip, wear-resistant and excellent in load-bearing performance, capable of withstanding frequent loading and unloading impact. The axles adopt high-quality brand axles, matched with high-strength leaf spring suspension and tubeless tire wheels, ensuring stable braking and smooth driving, with good wheel hub heat dissipation and safer braking on long downhill sections. The whole vehicle adopts automatic submerged-arc welding technology, with full and even weld seams and reliable strength. After shot blasting and electro-coating double anti-corrosion treatment, the paint film has strong adhesion and excellent corrosion resistance, capable of coping with harsh environments and long-distance transportation tests with ease.
