A side dump semi trailer — also sold as a side tipper semi trailer or side tipping trailer — is a semi-trailer whose body is hinged to the frame and raised sideways by hydraulic cylinders, so the cargo is discharged over the side rail rather than out of the back. The body carries a steel floor with 2.3 mm Q235 side walls divided into three or five doors per side, and each side door is hinged at the top so it lifts and swings clear as the body rises.
That design changes the haul cycle. A rear dump trailer has to reverse into position and needs a pit, an embankment or a clear run-out after tipping. The side dump trailer is loaded and unloaded from level ground: the tractor stays in line, the body discharges to the kerb side, and the unit drives straight out. On a quarry floor, a coal stockyard or a construction spoil tip, that keeps trucks moving instead of queueing for a turnaround.
This 3 axle side dump trailer is built for exactly that duty — a 9,000 mm body on three 13 t axles, on 12 tyres, tipping to one side as specified at order.
Hydraulic and pneumatic controls are grouped on the trailer, and the electrical system runs on standard 24 V with a 7-way harness, so the unit can be hooked to a normal 6×4 tractor rather than a dedicated prime mover.
Four φ125 mm lifting cylinders are paired with one φ140 mm cylinder. The body is hinged to the frame through the cylinders and slewing bearings, so the lift is a guided arc rather than a free tilt, and the 140 mm cylinder finishes the stroke at the point where the load breaks loose. The pump is driven from the tractor PTO, which keeps the trailer independent of a separate power pack.
Side walls are 2.3 mm Q235 steel, ribbed and divided into three or five doors per side. Doors are hinged at the top of the body so they turn up and out of the way as the body rises, and lock bars along the side rail keep the load contained in transit. The floor is a 3 mm steel plate, which is thick enough for direct bucket loading without a liner.
The 500 mm Q345B main beam runs 16 mm / 8 mm / 18 mm plate, supported by 16# channel side beams. Three 13 t FUWA axles with American-type mechanical suspension carry the load on 12 tyres, so the bogie keeps rolling even with a puncture. JOST D200T landing gear and a JOST 2.0 in or 3.5 in bolt-in kingpin are standard fittings, which means spare parts are available in most export markets.
The complete chassis is sand-blasted to remove mill scale and rust before painting, then finished with one anti-corrosive primer and two final coats. That preparation is the difference between a trailer that still looks like new after two seasons of coal or aggregate work and one that is being repainted at the first wash-down.
