Semi-trailer · Semi-trailers
Removable posts, and a build sheet rather than a fixed model. You choose the length, the axles and the suspension before we start.



A stake-side semi-trailer, manufactured in our own factory, and the one page in this catalogue where there is no single set of dimensions to print, because there is no single trailer. Length, axle count and axle brand are specified by you before the build starts.
The deck carries removable vertical posts along both sides. Pull them out and you have a flat deck. Drop them in and the load is contained. There is no fixed wall and no hinge, which is what separates it from our drop-side trailer.
What is settled by us is the quality of the parts that fail first. JOST dual-speed manual heavy-duty landing gear. A WABCO RE6 relay valve, T30/30 spring brake chambers and a 40-litre air tank. A 2 inch or 3.5 inch slip-on steering shaft. Suspension in air or mechanical, on airbags or steel-plate springs. Tyres and rims from the full range of common sizes, with steel rims optional.
Haulage and agriculture. It is bought by operators whose load is different every week and by co-operatives and produce buyers who need containment during the harvest and a flat deck for the rest of the year. Timber, drums, crates, sacks, palletised goods, machinery, building materials.
The posts are also the practical answer to loading from a place that has no dock. Take one section of posts out and a forklift works from the side, in a field, with nothing to reverse up to.
This is the part of our range that a used-truck exporter cannot offer, and it is worth being direct about why it matters. A used tractor unit is what it is. It has the cab it has, the engine it has and the axles it has, and your only decision is which of the ones in the yard to take.
A trailer we build is a set of decisions. If your roads are bad, mechanical suspension on steel springs is more repairable in the field than airbags and you should probably take it even though air rides better. If your loading is always kerbside, the post spacing matters more than the deck length. If your tyre supply locally is 12.00R20, order 12.00R20 and not 315/80R22.5, whatever looks better on paper, because the tyre you can buy in your own town is the one that keeps the trailer working.
Tell us the job and we will tell you what to specify. That conversation is the product.
New build. Powder coat in your colour. Because nothing here is fixed, the specification sheet is agreed in writing before any deposit, and it is what the Proforma Invoice describes. You get photographs from the shop while it is being built rather than only when it is finished.
Shipping volume depends on the length and the height you specify, so there is no figure on this page. Every other trailer here publishes its cubic metres because the build is fixed, and printing one for a trailer you have not specified yet would be a guess.
Send us the specification and we will come back with the volume and the freight to your port in the same message. We load at our yard in Tangshan and ship through Tianjin Port.
The load, the deck length you want, and the roads it will work on. Your tyre size if you have a local supply. Your destination port and the quantity. We will turn that into a specification sheet you can check before anything is built.
The dimensions, the axle count and the axle brand are yours to choose, and so are the suspension, the landing gear, the tyres and the rims. We build to the sheet. It is the opposite of a used tractor unit, where you take the truck that exists.
Air or mechanical suspension. Airbag or steel-plate springs. A 2 inch or 3.5 inch slip-on steering shaft. JOST dual-speed manual heavy-duty landing gear. WABCO RE6 relay valve with T30/30 spring brake chambers and a 40-litre air tank. Tyres in 11.00R20, 12.00R20, 11R22.5, 12R22.5 or 315/80R22.5, on 8.5-20, 9.0-20, 8.25-22.5 or 9.0-22.5 rims, steel optional.
The posts lift out. That gives you a flat deck when you want one and a contained deck when you want that, which suits a fleet whose loads change. A fixed drop-side is stronger and faster to load; a plain flatbed is cheaper and lighter. Stake sides are the flexible middle.
It depends on the specification and on what is already in the shop, so we will not print a number here that turns out to be wrong for your build. Send us the sheet and we will give you a real date before you pay a deposit.
Only what the catalogue actually prints. A row that is not here is a figure we do not have yet. Ask, and we confirm it against the machine in our yard rather than guess at it.
