3 Axles 40ft and 45 Feet Skeletal Container Truck Trailer Chassis

This 3-axle skeletal container trailer chassis hauls 40ft, 45ft, or twin 20ft ISO containers at 40-ton payload. The 500 mm I-beam main beam (upper 14 mm, lower 16 mm, middle 8 mm) is submerged-arc welded with shot-blasted stress relief. Twelve twist locks, FUWA 13-ton axles, 10/10/10 leaf springs, 28-ton dual-speed landing gear, 50/90 mm kingpin, and 12R22.5 tires.

Single 40ft, Single 45ft, or Twin 20ft Containers

Twelve high-strength twist locks positioned along the skeletal container trailer chassis give fleet operators the flexibility to switch container configurations without changing trailers: one 45ft box, one 40ft box, two 20ft containers end-to-end, or a single centered 20ft unit. The 12,500 x 2,500 x 1,600 mm skeleton frame maximizes payload while minimizing tare weight. Every kilo saved on the chassis is a kilo you can charge for in the container.

500 mm Submerged-Arc Welded I-Beam Spine

The skeletal container trailer's main longitudinal beam (500 mm web height, 14 mm upper flange, 16 mm lower flange, 8 mm middle web) is fabricated with automatic submerged-arc welding. After welding, the entire frame undergoes shot blasting to relieve internal stress and remove mill scale, followed by epoxy primer and dual polyurethane topcoats for long-term resistance to salt spray at coastal ports and container terminals.

Reinforced I-Beam Spine

The main longitudinal chassis beams of this skeletal container trailer are fabricated using submerged arc welding technology. High-tensile steel plates prevent structural deflection when carrying heavy, unevenly loaded 45ft shipping containers across port terminal speed bumps and rough rail-yard surfaces.

12-Twist Lock Multi-Configuration Layout

Twelve strategically positioned high-strength twist locks allow a single skeletal container trailer chassis to carry a 45ft box, a 40ft box, two 20ft containers end-to-end, or a single centered 20ft unit. No trailer swap required between pickups. Fleet utilization improves immediately.

Low Tare Weight, Higher Legal Payload

By eliminating unnecessary deck plating, the skeleton frame design of this skeletal container trailer cuts deadweight while retaining full structural strength. The result: more net payload per trip within legal axle-weight limits, plus lower fuel consumption on empty return legs to the port or rail terminal.

Severe-Duty Suspension and Axle Assembly

Heavy-duty FUWA axles paired with reinforced leaf springs and equalizer arms absorb harsh road impacts from unpaved port terminals and rough highway stretches, protecting both the skeletal container trailer chassis and the container cargo from vibration fatigue over thousands of drayage cycles.

28-Ton Dual-Speed Landing Gear

The dual-speed landing gear supports fully loaded 40ft and 45ft containers during tractor decoupling. High gear for fast positioning, low gear for cranking under load. A single driver can raise or lower a loaded skeletal container trailer without assistance at a drop yard or container storage facility.

Shot-Blasted, Epoxy-Coated for Port Environments

The entire steel frame of this skeletal container trailer undergoes automated shot-blasting to remove rust and mill scale, followed by epoxy primer and dual polyurethane topcoats. This finish system provides long-term resistance to the salt spray, humidity, and chemical exposure common in coastal port terminals and container yards.

Port Terminal and Drayage Operations

Moves international shipping containers rapidly between container ships, dockyards, and bonded storage areas. The skeletal container trailer's lightweight frame keeps turnaround times short and fuel costs low on short-haul port loops where every minute of dwell time erodes margin.

Intermodal Rail-to-Road Transfer

Serves as the primary link for moving sea containers off railway flatcars and transporting them directly to inland distribution hubs. The skeletal container trailer chassis accepts containers from overhead gantry cranes and reach stackers without requiring the driver to exit the cab during loading.

Cross-Border Long-Haul Freight

Enables long-distance logistics providers to shuttle sealed 40ft and 45ft containers across regional highway corridors securely. The skeletal container trailer's stable tracking and balanced brake distribution keep fully loaded boxes planted through mountain passes and crosswind-prone open stretches.

Container Yard and Depot Management

Flexible twist-lock positioning means one skeletal container trailer chassis handles mixed container inventories (20ft empties, 40ft reefers, 45ft high-cubes) without returning to the depot for reconfiguration between assignments.

Bulk Ship or Ro-Ro with Tractor Unit

The primary shipping method for a skeletal container trailer chassis is by bulk cargo vessel or Ro-Ro ship with a tractor truck towing the unit on and off the vessel deck. No disassembly required. The trailer arrives ready to couple to your existing fleet tractor.

Container Shipping with Tail Section Removal

The skeletal container trailer can also ship in a container, but the tail section must be cut before loading. Reassembly at destination is straightforward (welding and bolting at marked connection points) and we provide a reassembly guide with torque specs and weld procedures.

20+ Years of Trailer Manufacturing

Chengda Trailer, established in 2005, builds skeletal container trailers from 40ft standard chassis to 45ft extendable gooseneck configurations. Every unit undergoes a full frame geometry check and twist-lock alignment verification before release. Competitive pricing with quality assured.
