HYVA front cylinder
The cylinder at the front raises the body for rear tipping and lowers it after unloading.
This tandem-axle rear dump semi trailer hauls sand, gravel, coal and other loose bulk. A front-mounted HYVA cylinder tips the high-sided body so the load runs out through the rear gate, and an electric tarpaulin covers it on the road.
The rectangular body is 6,600 mm long, 2,300 mm wide and 1,400 mm deep inside, with lower sides that slope toward the floor. A HYVA 191 x 5600 cylinder at the front lifts the body and the load flows out through the rear gate. An electrically operated tarpaulin closes over the top for transport. In load tests at our factory the trailer carried about 30-40 tonnes; the payload you can run depends on cargo density and the weight limits on your route. The two 13 t axle ratings are component ratings, not the trailer payload.

Three parts handle loading, transport and unloading.

The cylinder at the front raises the body for rear tipping and lowers it after unloading.

The gate holds the load on the road and opens for discharge. Wet or sticky material flows out more slowly.

The tarp extends and retracts electrically, limiting wind loss on the road and opening for loading from above.
Two axles 1,310 mm apart sit under the rear of the body.

Two FUWA axles rated 13 t each, on 315/80R22.5 tyres.

Landing gear and a 600 x 600 mm toolbox sit ahead of the axle group; the side guard is on the left.

Straight upper sidewalls with lower sides sloping toward the floor help the load slide out.
Outside dimensions decide route and yard clearance; inside dimensions decide how much material fits.
Specifications from the general arrangement drawing. Payload and tare weight are not stated on the drawing; the 30-40 t figure comes from factory load tests.

The same body volume holds very different weights of sand, gravel and coal. Tell us your material and we size the body.
Sand from supply yards to sites and concrete plants. Load from above, tip at the delivery point.
Crushed stone and gravel for roads and buildings. Stone size and loading impact decide the floor specification.
Loose coal between stockyards and receiving sites, discharged through the rear gate.
The 6,600 x 2,300 x 1,400 mm body holds about 21 cubic metres level-full, but that volume weighs very differently by material: dry sand is far heavier per cubic metre than coal. A bigger box does not raise the permitted load, which is set by axle and tyre ratings, the tractor and your road limits. Send the material and its bulk density, and we size the body so a full load stays within your legal weight.
FUWA 13 t axles are fitted as shown. If your fleet services other brands, choose them here.
