Operators This Trailer Is Built Around
- Building material suppliers delivering block, pipe and palletised goods to sites with no loading dock
- General haulage fleets that switch between contained bulk cargo and oversized flat loads
Problems It Solves
Fixed sides block side loading
Foldable side panels drop away so a forklift can load from either side instead of working over the tail.
Rough site roads shake a light chassis apart
High-strength steel with a flat, stable chassis structure and a sturdy suspension system is specified for harsh transportation environments.
What You Get For the Money
Over 30,000 kg payload
Rated above 30 tons with 13-ton FUWA axles, so construction materials do not have to be split across two trips.
2, 3 or 4 axles
Choose the axle count that matches your local road limits and the weight you actually run.
Mechanical or air suspension
Mechanical for repairability on poor roads, air where load protection and ride matter.

How It Compares
A flatbed trailer is cheaper and lighter but cannot contain loose cargo. A fence trailer gives higher stake sides for volume loads. The drop side sits between them: contained sides when you need them, an open deck when you fold them down.
Operating Notes
- Latch every side panel before moving off, including the ones you did not open.
- Spread heavy point loads across the deck rather than over a single cross member.
- Grease the panel hinges on the same schedule as the suspension.
Every vehicle ships with an illustrated operation manual covering coupling, braking and turning technique.
