3 Axle Skeleton Semi Trailer
40ft Container Shipping Skeleton Chassis
Product Overview
40ft Shipping Container Chassis
ZW Group 3 Axle 40ft Container Shipping Skeleton Trailer is a high-strength, low-weight container chassis built to meet international standards. With a robust structure and precision manufacturing, it offers excellent load capacity, corrosion resistance, and low maintenance costs.
Features & Advantages
1. Heavy-Duty Chassis Frame – Built for Strength and Stability
The skeleton trailer's main beam is made from Q345B high-tensile steel, using automated submerged arc welding technology to ensure structural integrity under heavy loads. The frame is reinforced at critical stress points to prevent deformation and fatigue cracking even under prolonged operation and rough road conditions.
Welding Method: Submerged arc + robotic welding
Beam Profile: Optimized I-beam structure for superior load distribution
Anti-corrosion Coating: Shot-blasted + high-performance primer + polyurethane finish
2. Versatile Container Locking System
Equipped with 8 sets of twist locks that are compatible with both 20ft and 40ft containers, the trailer supports dual loading configurations. The twist locks are made from cast steel, heat-treated for extra strength and corrosion resistance.
ISO Standard Twist Locks (Heavy Duty)
Automatic or manual twist lock options available
3. Advanced Axle & Suspension System
Fitted with 3 x 13–16 ton axles from trusted brands (FUWA, BPW, or ZW proprietary), the trailer guarantees smooth handling even when fully loaded.
The mechanical leaf spring suspension offers superior stability and shock absorption, or you can upgrade to air suspension for added comfort and reduced tire wear.
Suspension Options: Mechanical leaf spring, air suspension, bogie suspension
4. Reliable Braking System with Safety Enhancements
The braking system consists of dual-line air brakes with high-performance chambers, ensuring fast, reliable braking response. ABS is optional, which greatly improves safety during emergency stops or slippery road conditions.
Brake Chamber: T30/30 spring brake chambers
Air Tank: 40L dual chamber tank system
5. Efficient Design for Cost-Effective Transport
With an empty trailer weight starting around 6–7 tons, this skeleton trailer is optimized for lower fuel consumption without sacrificing strength. Its skeletal structure minimizes tare weight and maximizes payload capacity, increasing your overall profitability per trip.
Fuel Efficiency: Lightweight structure for reduced consumption
Load Capacity: Up to 60 tons payload
