Skeleton Semi Trailer 40ft for 20ft/40ft Containers, 3 Axles

The skeleton semi trailer is a steel container chassis built to move 20ft and 40ft boxes between port stacks, rail ramps and mine sites. Fleet operators choose it because the bare frame carries the load and keeps the deck clear for twist-lock handling. This heavy duty unit is a brand-new build aimed at buyers who move containers every day.

Why It Works On Site

• 50T load capacity takes dense, fully loaded boxes without the frame flexing under the twist locks.
• 2, 3 or 4 axles rated 13T or 16T let you match axle count to the payload and road rules on your route.
• Mechanical or air suspension gives a simple steel spring setup for rough ground or a softer ride for long highway legs.
• 28t heavy duty landing gear holds a loaded chassis steady while the tractor is swapped or the box is dropped.
• 2″ (50mm) or 3.5″ (90mm) king pin matches the fifth wheel already in your fleet.
• Valve brake system keeps braking control consistent when the trailer runs at gross weight.

Where It Is Used

Port and terminal work is the core job: shuttling 20ft and 40ft boxes between the quay, the yard and the gate. The same chassis suits rail ramps, where containers are lifted on and off in tight cycles.

On mine and plant sites it carries tooling and spares in containers over unsealed haul roads. The flat skeleton frame keeps weight low and leaves the corners open for inspection.

Customisation Before Delivery

Axle count and axle rating, suspension type, king pin size and tyre size are all chosen at order confirmation. Tyre options include 11.00r20, 12r22.5, 315 and 385 fitments, so you can match the rubber already stocked in your workshop. Tell us the container sizes you run and the tractor you pair with, and the build is fixed before production starts.
