Three-axle Low-bed Semi-trailer

Positioning of basic vehicle specifications

This is a specialized tri-axle low-bed semi-trailer designed for transporting construction machinery. Featuring a fixed, reinforced ramp structure, it is primarily used to haul heavy equipment such as excavators, loaders, road rollers, drilling rigs, and crushing machinery. It is a mainstream model in high demand across mining and infrastructure sectors in Africa, Southeast Asia, and South America.
Load Capacity: Rated for 40–60 tons with a tri-axle configuration;
Deck Design: Drop-deck (gooseneck) low-profile design; the low loading height ensures a stable center of gravity and enhances safety during the transport of oversized cargo;
Tractor Compatibility: Compatible with mainstream 4×2 and 6×4 tractor units, allowing for connection with standard tractor models worldwide.

Main Frame Manufacturing Process

Main Beam Construction:
Constructed using high-strength, continuous W-profile main beams formed via fully automated submerged-arc welding. The webs and flanges (top and bottom plates) are thickened to provide superior resistance to torsion and heavy-load deformation, ensuring durability against cracking or warping during long-term operation on the rough, muddy, and rocky roads typical of mining areas. The continuous, integrated frame design ensures even load distribution, effectively preventing structural failure caused by localized stress concentrations.
Side Beams and Decking:
Equipped with thickened, impact-resistant side beams. Integrated rope tensioners and lashing rings are welded around the perimeter, facilitating the secure fastening of heavy machinery with steel cables or tensioners and preventing equipment slippage during transport. The deck features anti-slip checkered steel plating that is wear-resistant and capable of withstanding high pressure, preventing equipment tracks from slipping.
Exterior Finish:
The entire vehicle undergoes sandblasting and rust removal, followed by the application of an epoxy primer and a matte, wear-resistant topcoat (dark gray as shown), ensuring resistance to corrosion and the elements. High-visibility yellow reflective strips run along the sides to comply with international night-time road safety regulations; the vehicle is fully equipped with the necessary lighting and reflectors for customs clearance and registration.
