It discharges sideways. For sites where there is nowhere to reverse into and no headroom to raise a body.

A 13 m side rollover semi-trailer, manufactured in our own factory. Instead of raising the front of the body to tip out the back, the body rotates about its own long axis and discharges over the side.
Three 13-tonne axles. Overall 13.00 by 2.55 by 3.00 m. The beam is 8 mm on the top flange, 10 mm on the bottom and 6 mm through the web, on a 6 by 8 by 3.5 mm subframe. Tyre options run 11.00R20, 12.00R20, 11R22.5, 12R22.5 and 315/80R22.5, and the finish is powder coat to your requirement.
Haulage and construction, in the specific situations where a rear tipper does not fit the work.
Windrowing. Laying material in a continuous line along a haul road, a verge or a pipeline trench, without stopping to reposition. A rear tipper puts the whole load in one heap.
Low clearance. Under a conveyor, inside a shed, beneath a gantry or a power line. A rear tipper stands its body six or seven metres in the air to empty. This one never rises above its own loaded height.
Sites with no room behind. Reversing thirteen metres of trailer into position takes time and space, and on a busy site it takes a banksman. Sideways discharge means you drive to the line and empty as you go.
This trailer and our U-dumping trailer are both tipping trailers we build, and they answer different problems.
The U-dumping trailer is the one for wet and sticky material, because the round bottom has no corners to pack, and it is the cheaper of the two to ship at 73.4 m³. It needs space behind and headroom above.
This one is 99.5 m³, a third more on the vessel, and it buys you discharge in places the other cannot work at all.
There is one honest limitation, and it is better on this page than in a conversation after you have paid. Rolling a loaded body to one side moves the centre of gravity off the chassis centreline. On firm, level ground that is routine and the design accounts for it. On soft ground, a camber or a side slope, it is not, and the discharge side needs to be the solid side. If most of your tipping is on unprepared ground, the rear tipper is the safer trailer and we will tell you so.
New build, from our own workshop. Powder coated to the colour you ask for. Axle brand, tyre and rim sizes and the paint specification are agreed before the build starts. Photographs come to you from the shop while it is being built, not only when it is finished.
99.5 m³, calculated from the overall dimensions. That is the joint largest figure in this catalogue, alongside the 13 m drop-side built on the same chassis, and sea freight is charged on it rather than on the weight.
It is worth putting next to the alternative: the U-dumping trailer at 73.4 m³ gets to your port for meaningfully less. Buy the extra volume because you need side discharge, not because the trailer is longer.

Where and how you discharge, and what the ground is like there. The material and whether it is wet. Your destination port and the quantity. If you need the prime mover as well, we will price both on one booking.
A rear tipper lifts the front of the body and needs both space behind it and clearance above it. This one rolls the body over to one side. You unload alongside the trailer instead of behind it, and the trailer never stands nose-up.
Windrowing material along a road or a haul route, unloading under a low structure or a conveyor, and any site where reversing a 13 m trailer into position is slow or unsafe. If you always tip into a hopper or over an edge, a rear tipper is simpler and cheaper.
Rolling a loaded body to one side puts the load off the centreline, so ground conditions matter more than they do with a rear tipper. It wants level, firm ground under the discharge side. Tell us the ground you work on and we will be straight with you about whether this is the right trailer.
Three 13-tonne axles, with the beam at 8 mm on the top flange, 10 mm on the bottom and 6 mm through the web, on a 6 by 8 by 3.5 mm subframe. Powder coated to your requirement, and tyres from 11.00R20 through 315/80R22.5.
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.
