Low-Bed Semi-Trailer With Ramps-Tianjin Match Machinery Co.,Ltd.

Technical characteristics

The low flatbed semi-trailer with Ramps is a special heavy-duty transport vehicle optimized for loading and unloading self-propelled construction machinery. It retains the ultra-low cargo platform design of conventional low-bed semi-trailers, and is equipped with a reinforced climbing ladder structure at the rear of the vehicle. This design allows engineering equipment such as excavators, road rollers and loaders to drive onto the cargo platform independently without the assistance of additional lifting equipment, making it widely used in infrastructure construction, large equipment transfer and other scenarios.

Features

1. Integrated Ladder Design‌
The rear-mounted reinforced climbing ladder can be made of high-strength steel or configured with a hydraulic lifting structure. It has strong bearing capacity, effectively reduces the gradient of the climbing section, and ensures that heavy engineering machinery can safely drive onto the vehicle.

2. Ultra-low Center of Gravity Structure‌
It adopts a concave-beam frame with an I-shaped longitudinal beam. The main plane of the cargo platform is extremely low, which greatly reduces the overall center of gravity of the vehicle, effectively avoids the risk of over-height during transportation, and significantly improves the stability of driving with heavy loads.

3. High Load-bearing Performance‌
The whole frame is formed by advanced welding process and shot peening treatment, with high rigidity and strength. The load capacity can cover 20-100 tons, which can meet the transportation needs of various large construction machinery and heavy equipment.

4. Stable Force Transmission System‌
It is equipped with a multi-axle balanced suspension structure. The mass balance block installed between the front and rear leaf springs can make the stress of each axle uniform, effectively reduce the wear of tires and suspension parts, and adapt to long-distance heavy-load transportation conditions.
