CURTAIN SIDE CARGO TRAILER
3 Axle Curtain Side Semi Trailer
This three-axle curtain side semi trailer carries palletized and packaged freight. A forklift can reach the load from the side after the curtain is drawn back, while the double rear doors serve a loading bay.
A rigid front bulkhead and roof frame form the cargo body. Buckles along the lower rail pull the curtains tight when the sides are closed. The curtains cover the freight, but the load still needs its own securing arrangement.
The three axles sit beneath the rear of the floor. Landing legs support the front when the trailer is uncoupled; a side guard and toolbox are mounted under the loading area.
Can You Load This Curtain Side Trailer from the Side and Rear?
The side curtain and rear doors close independently on this three-axle curtain side semi trailer. The fittings below are part of the trailer body; cargo inside still needs its own restraints.
SIDE CURTAIN
Fastened along the lower rail
Black straps run down the grey curtain to the buckles at the lower side rail. This row holds the curtain's bottom edge in place when the body is closed; the straps are released before the curtain is moved aside for loading.
The landing leg, side guard and toolbox are mounted below the curtain line, separate from the buckles used to close the side.
REAR OPENING
Two doors at the back
The metal door leaves meet at the centre of the rear opening. They provide a separate route for loading from behind, so the side curtain can stay closed when rear access is preferred.
Hinges are fitted at the outside edges of the doors, with the rear bumper and lamps below. This rear opening and the side curtain give the operator two distinct ways to reach the cargo body.
CARGO APPLICATION
What Is a Curtain Side Trailer Used For?
This body is intended for palletized and packaged dry freight that needs a covered cargo space with side or rear access.
Match the body to the freight and loading method
The curtain opens along the side for forklift access, while the rear doors serve a loading bay. The curtains close the cargo body during transport but do not replace the load's own restraints.
- Palletized freight
- Side access lets a forklift reach pallet positions along the cargo floor.
- Packaged dry goods
- The roof, front bulkhead, rear doors and closed curtains form the covered cargo body.
- Confirm before production
- Check cargo dimensions, transport weight, loading method and securing points against the final drawing.

3 Axle Curtain Side Trailer FAQs
These answers are based on the photographed trailer and its supplied reference drawing. Final dimensions, equipment and cargo-securing arrangements are confirmed for each order.
What is this 3 axle curtain side semi trailer designed to carry?
It is intended for palletized and packaged dry freight that needs a covered cargo body with side or rear loading access. Cargo dimensions, transport weight and the loading plan must be checked before the final configuration is approved.
Can the trailer be loaded from both the side and the rear?
Yes. Releasing and opening the side curtain gives forklift access along the cargo floor. The double rear doors provide a separate route for loading from a dock or from behind the trailer.
What are the internal dimensions of the curtain side trailer?
The reference internal dimensions are 12,440 mm long, 2,510 mm wide and 2,680 mm high. The reference external dimensions are 12,750 mm long, 2,600 mm wide and up to 4,400 mm high. The approved production drawing is the final dimensional record.
Do the side curtains secure the cargo?
No. The curtains close the cargo body, but they do not replace suitable load restraints. The securing method and required anchorage points must be selected for the cargo and the rules that apply on the destination route.
Can the cargo-body height or roof opening be adjusted?
The supplied drawing states that the upper beam and roof opening can be adjusted, with total height not exceeding 4,400 mm. The required opening and final overall height should be agreed on the production drawing.
What information is needed for a quotation?
Please provide the cargo type, packed dimensions, transport weight, loading method, destination country or port, required quantity, applicable standard and target delivery date. This information is used to prepare the configuration and quotation.
