How It Compares
Against our 12.4 m dropside manufacturer model, this 40-foot build offers more floor and suspension choices. Against a fence trailer, the lower flip-side rails favour forklift access over cargo volume.
Operating Notes
- Match tie-down points to the load, do not rely on the side panels to restrain cargo.
- Inspect the diamond plate floor for deformation after heavy point loads.
- Drain air tanks regularly in humid climates.
Every vehicle ships with an illustrated operation manual covering coupling, braking and turning technique.

Which floor thickness should I order?
3 mm is adequate for palletised goods. Choose 4 mm or 6 mm if tracked or wheeled plant is driven onto the deck, or if you load steel with sharp edges.
What does bogie suspension change?
Bogie suspension is robust and simple and handles poor roads well. Air suspension protects fragile cargo and gives a better ride. Spring suspension sits between the two on cost.
Can you supply matching spare parts?
Yes. Order spare brake chambers, leaf springs and lamps with the trailer and they ship in the same container.
Do you ship to my country?
SINOHENG exports in bulk to 30+ countries and regions across Southeast Asia, Africa, the Middle East and South America. Send your destination port with the enquiry and we will quote delivery with the trailer.
Ask for a Drawing Before You Commit
We confirm dimensions, axle loads and coupling height on an approval drawing before any steel is cut, so the trailer is legal and couples to your tractors.
