1. Overview

The 3-axle skeleton semi-trailer, also known as a container chassis, is specifically designed for transporting ISO containers (20ft, 40ft, or 45ft). The lightweight "skeleton" frame minimizes tare weight while maximizing payload capacity. This trailer is the industry standard for port-to-depot container logistics, offering simplicity, durability, and easy maintenance.

2. Key Features

• Lightweight skeleton frame – High-strength I-beam construction minimizes tare weight for higher payload

• Dual-position twist locks – Manually operated or automatic; accommodate 20ft, 40ft, and 45ft containers

• 3 axles – 13T–16T per axle, total GVW 40–48 tons

• Reinforced front and rear bolsters – Absorb container impact and locking forces

• Heavy-duty suspension – Mechanical leaf spring (standard) or air suspension (optional)

• ABS braking system – Standard, with EBS optional

• Spacer / slider option – Adjustable twist locks for flexible container positioning

• Container guide plates – Easy container alignment during loading

• Landing gear – 2-speed heavy-duty, 28–30T capacity

6. Buying Guide

Provide the following for an accurate quote:

1. Container types used (20ft / 40ft / 45ft / mixed)

2. Typical cargo weight (light / standard / heavy)

3. Operating route (short haul port-to-depot / long haul inland)

4. Tractor fifth wheel height (mm)

5. Destination country (for axle load and lighting regulations)

6. Optional needs (reefer fuel tank bracket, side underrun guards, toolbox, air suspension)

Key tips:

• Mixed 20ft + 40ft operation → Choose Slider model (adjustable twist locks)

• Heavy cargo (>30T) → Choose 16T axles + reinforced main beam

• Long haul / reefer containers → Choose air suspension for cargo protection

• Budget / dedicated 40ft route → Fixed model is most cost-effective
