Multi-Axle Gooseneck Lowboy Semi-Trailer, load capacity 50/80/100/120 tons, ultra-low deck design for heavy machinery haulage, equipped with hydraulic foldable ramps

This heavy haul lowboy trailer has load options of 50t, 80t, 100t and 120t. It adopts detachable gooseneck design for easy connection and separation with tractors. The frame is made of thick high-strength manganese steel with double main beams and dense cross beams, featuring outstanding torsion resistance for long-term heavy loads without deformation. The ultra-low deck design lowers overall transport height, complying with height limits for oversized heavy machinery.

Equipped with multi-axle balanced suspension and heavy-duty Fuwa/BPW axles, weight is evenly distributed to reduce road pressure. Heavy-duty tires and large brake drums guarantee stable and safe braking on mountain roads, mining tracks and highways. Hydraulic foldable ramps come as standard, electrically powered for effortless lifting and folding. The anti-slip ramp surface allows self-driving loading of excavators, loaders and rollers, greatly cutting loading time; folded ramps stay close to the deck without extra wind resistance during transit.

Perfect for hauling construction machinery, mining equipment, transformers, steel structures and heavy farm machines across construction sites, mines and long-distance highways. We offer full OEM & ODM customization: adjustable axle quantity, deck size, extendable widening plates, custom painting and logos to meet local road weight regulations.

Core advantages: low deck to avoid height restrictions, strong multi-axle load capacity, automatic hydraulic ramps for efficient loading, anti-rust heavy-duty frame, and complete tonnage options for all heavy equipment transport demands.
