Tri Axle 40 Feet Skeleton Container Trailer Chassis

This tri-axle 40ft skeleton container trailer chassis carries one 40ft or two 20ft ISO containers at 40-50 tons on a Q345B submerged-arc welded main beam (500 mm web). Twelve twist locks, JOST 50/90 mm kingpin with JOST 28-ton dual-speed landing gear, and WABCO dual-line pneumatic brakes. Fuwa or BPW 13T/16T axles on 12R22.5 or 12.00R20 tires. Shot-blasted, primed, and polyurethane top-coated for port environments. BV, WMI, CCC, ISO9001 certified.

12 Twist Locks - One 40ft or Two 20ft Containers

Twelve ISO-standard twist locks are positioned along the 12.5-metre chassis to accept a single 40-foot box, two 20-foot containers end-to-end, or a single 20-foot unit centred on the frame. Fleet operators running mixed container inventories do not swap trailers between pickups - the same skeleton container trailer chassis handles all three configurations with a twist of each lock handle.

Q345B I-Beam at 500 mm Web Depth

The main beam uses Q345B high-tensile carbon steel assembled by automatic submerged-arc welding - the same process used on heavy-haul low-bed trailers. A 500 mm web height gives the skeleton trailer chassis the bending resistance to carry a fully loaded container without sagging at the midpoint, while the open-frame design strips out every kilo of steel that is not structurally necessary.

Q345B Steel Main Beam - No Sag Under 50-Ton Loads

The 500 mm deep I-beam spine is fabricated from Q345B carbon steel plate with automatic submerged-arc welding along the full web-to-flange joint. This girder design resists both bending under a centred 40ft container and twisting when a single 20ft box sits at one end of the skeletal semi trailer chassis. Rolling across dockyard expansion joints and speed bumps at the container terminal does not fatigue the beam over thousands of cycles.

Fuwa or BPW 13T/16T Axles with Heavy Leaf Springs

Choose between Fuwa or BPW axle sets rated at 13 or 16 tonnes per axle, paired with a 10-piece heavy-duty leaf spring suspension. The suspension absorbs the repeated impact of container stacking and crane loading without losing camber, and the axles run on 12R22.5 tubeless or 12.00R20 radial steel tires - 12 in service plus one spare carrier-mounted.

Shot-Blasted Steel, Polyurethane Finished

Every skeleton container trailer chassis is shot-blasted to remove mill scale before painting. Anti-rust primer goes on first, followed by a durable polyurethane topcoat formulated to resist salt spray, tropical humidity, and the chemical exposure common around port terminals and container storage yards. The result is a chassis that still looks presentable after five years of coastal duty.

Bulk Vessel or Ro-Ro with Tractor Unit

The primary shipping route for this 40-foot skeleton container trailer is by bulk cargo ship or Ro-Ro vessel with a tractor truck towing the unit onto the deck. No cutting, no disassembly - the chassis arrives at your port ready to couple to your fleet tractor and start hauling containers the same day.

For containerised shipping, the tail section of the skeleton trailer is cut before loading and reassembled at destination by welding and bolting at marked connection points. We provide a step-by-step reassembly guide with torque values - a competent welding shop can complete the job in under two hours.

BV, WMI, CCC, ISO9001 Certified Manufacturing

Our factory holds BV, WMI, CCC, and ISO9001 certifications covering the design, welding, assembly, and inspection of every skeletal semi trailer that leaves the production line. The certificate pack ships with your documentation, simplifying customs clearance at the destination port.
