This 3 axle curtain side semi trailer carries palletized and packaged dry freight. A forklift can reach the load from the side once the curtain is drawn back, and the double rear doors serve a loading bay.
The body has a fixed front bulkhead and a roof frame, with curtains on both sides that are buckled down along the lower rail. Two metal doors at the back open to a loading dock, so the side curtain can stay shut when you load from behind. Curtains protect the cargo from weather but do not hold it in place; plan your own lashing and anchor points. All sizes on this page are reference figures from the supplied drawing, and the approved production drawing is the final record.

The side curtain and the rear doors work independently, so you can choose the route that suits the dock or the forklift.
Straps run from the curtain down to buckles on the lower side rail. Release them before drawing the curtain back for side loading. The landing leg, side guard and toolbox sit below the curtain line.
The door leaves meet in the centre of the rear opening and are hinged at the outer edges. Use them for dock loading while the side curtain stays closed.
The cargo body sits on a full-length chassis with three axles under the rear of the floor.
Two longitudinal beams run from the coupling section to the rear, joined by crossmembers beneath the loading floor.
All three axles are grouped under the rear section of the body, below the lower curtain rail.
An open rack under the side rail near the rear wheels keeps stored items outside the curtained cargo space.
Use the internal size to check your pallet layout and the overall size to check route and yard clearance.
The upper beam and roof opening can be adjusted, with total height not above 4,400 mm. These are reference dimensions for discussion; the production drawing is approved before manufacture.
A 37-second walkaround from the front bulkhead to the rear: curtain buckles, landing gear, side guards, axle group and rear structure.
Match the body to the freight, the loading method and your route limits.
Side curtains let a forklift reach pallets along the floor. Rear doors serve a dock. Tell us which you use most.
Check packed dimensions and transport weight against the internal size and the axle-load limits on your route.
Axle number, suspension type and ride height can be configured. Confirm the tractor interface and route before production.
A curtain side semi trailer sits between a box van and a flatbed. Like a box van, its roof, front bulkhead, curtains and rear doors keep palletized cargo out of rain and dust. Like a flatbed, the curtains slide back so a forklift can load the full length from the side, without waiting for a rear dock. Choose a box van when you need fully rigid, lockable walls; choose a flatbed for oversized or crane-loaded cargo; choose a curtain side trailer when you move covered pallets and need fast side loading.
Choose the running gear to suit your loads, roads and local parts supply. The final configuration is confirmed on the approved drawing before production.
