Product Details

4 Axle Drop Side Wall Semi Trailer | 60-80 t With Detachable Side Boards

This four-axle drop side wall semi trailer carries 60–80 tonnes on four 13 or 16 tonne FUWA or BPW axles, with air lift available on the first axle. The side wall boards drop down on their hinges or lift out of the pockets entirely, so the trailer loads from the side by forklift for bagged cement, aggregates and palletised freight, and runs as an open deck once the walls are off.

Transportation & Export Handling

Trailers ship waxed and painted so seawater cannot reach the steel during ocean transit, and we choose between three loading methods to keep your freight cost down. We compare the available sailings and quote the lowest landed cost for your port.

* Freight depends on port, sailing schedule and unit count — ask us for a landed-cost comparison.
