Product Advantages
Superior Load Capacity
This trailer features a five-line ten-axle design with a load capacity of 50-130 tons, evenly distributing pressure to prevent localized overloading. The main beam is manufactured from high-strength alloy steel, ensuring exceptional stability and resistance to deformation. Each axle undergoes rigorous testing to adapt to various rough road conditions, making it ideal for transporting heavy construction machinery.
Efficient Loading and Unloading
Equipped with a hydraulic detachable gooseneck, tracked equipment such as excavators and bulldozers can drive directly onto the platform without cranes. The hydraulic system is simple to operate, allowing one person to complete gooseneck detachment quickly. The low deck height ensures smooth and safe equipment movement, reducing loading time by more than 50% compared to traditional trailers.
Durable and Robust Structure
The entire vehicle is welded from high-strength alloy steel with reinforced key areas for excellent torsion resistance. The frame is optimized through finite element analysis to ensure even stress distribution and extended service life. The surface undergoes shot blasting and anti-corrosion painting, providing strong resistance to moisture, dust, and harsh environments.
Wide Application Scenarios
This trailer is designed for mines, wind farms, oil fields, and large construction projects, transporting excavators, bulldozers, rollers, and wind turbine blades. Platform length and width can be customized based on cargo dimensions. Excellent passability ensures smooth operation on rugged roads or soft construction sites.
Flexible Customization Services
We support customization of dimensions, colors, axle spacing, and tire specifications based on requirements. Factory direct supply offers competitive pricing with professional engineering consultation. Production cycles are short, with standard orders delivered in 20-25 days, all backed by a 12-month warranty.
Customer feedback
John M. – Mining Contractor, South Africa
"We purchased three five-line ten-axle lowbed trailers for our coal mining operation. They've been running for over eight months now, carrying 100-ton excavators daily. The hydraulic detachable gooseneck saves us at least two hours of loading time per shift. Strong build quality and no maintenance issues so far."
Vikram S. – Infrastructure Developer, India
"We needed customized lowbeds for transporting wind turbine components. The factory team worked with us on the design, adjusting platform length and axle spacing. The trailers arrived exactly as specified. After one year of heavy use, they show minimal wear. Good after-sales support too."
Michael T. – Construction Company, Australia
"Bought two units for transporting excavators and dozers across multiple project sites. The hydraulic gooseneck is reliable and easy to operate. Trailers track well at highway speeds and handle off-road conditions properly. Good value for money compared to European brands."
