40FT 3-Axle Skeleton Semi-Trailer

Product Overview

The 40FT 3-Axle Skeleton Semi-Trailer is specially designed for the safe and efficient transportation of standard 40-foot shipping containers. With an overall length of approximately 12.5 meters and a stable three-axle configuration, it is an ideal solution for ports, container terminals, logistics companies, freight forwarders and long-distance transportation fleets.

The entire trailer frame is manufactured using robotic automatic welding technology, ensuring consistent weld quality, high structural strength and excellent dimensional accuracy. Shot blasting is applied before painting to remove rust, oxide scale and surface impurities. The electrostatic powder coating and high-temperature baking process creates a strong protective finish with outstanding corrosion resistance.

Robotic Automatic Welding

The main frame of the 40FT 3-Axle Skeleton Semi-Trailer is welded using automated robotic welding equipment. This process provides uniform weld seams, accurate component positioning and consistent structural quality.

Compared with conventional manual welding, robotic welding helps reduce welding deformation and improves the strength and durability of critical structural connections. It also ensures reliable performance during frequent loading, unloading and long-distance transportation.

Shot Blasting and Rust Removal

Before applying the surface coating, the complete trailer frame undergoes professional shot blasting treatment. This process removes rust, oxide scale, welding residue and other contaminants from the steel surface.

Shot blasting also increases surface roughness, allowing the powder coating to bond more firmly to the trailer frame. This preparation helps prevent premature peeling, cracking and corrosion, particularly in humid, coastal and high-salinity operating environments.

Electrostatic Powder Coating and High-Temperature Baking

After shot blasting, the trailer is finished with electrostatic powder coating and high-temperature baking technology. The powder is evenly applied to the metal surface and cured at high temperature to form a dense and durable protective layer.

This coating process offers several advantages:

• Strong resistance to rust and corrosion
• Uniform color and smooth surface finish
• Excellent coating adhesion
• Improved resistance to scratches and weather exposure
• Longer service life with lower maintenance requirements
• Suitable for ports, coastal regions and harsh working conditions

Stable Three-Axle Structure

The three-axle configuration provides stable load distribution and dependable road performance. It helps improve vehicle balance during container transportation and ensures reliable operation over long distances.

The axle brand, suspension system, tire specifications and braking system can be selected according to customer requirements, local road conditions and transportation regulations.
