Joskin SIROKO

Narrow Body

At first glance, one might think that a narrow body has less capacity than a wide one, but when comparing volumes, it quickly turns out to be an optical illusion. Just like the Siroko, narrow bodies do indeed benefit from a lowered design and both side walls are often higher than on wide-body muck spreaders. This makes it furthermore considerably easier to load material. The body in high tensile steel (grade 550) is made up of successive folds and has a very sturdy rectangular upper strip. Depending on the Siroko model, the side walls are 850 mm, 1,090 mm or 1,340 mm high, for a loading capacity from 5 m³ to 14.17 m³ (+ possibility to add extensions). The moving floor of the Siroko consists of 2 Ø 14 mm marine chains with grade 80 (the highest grade in traction chains currently available) welded to slats with closed profiles. It moves on a bolted galvanised floor, which can be replaced easily in case of wear. This moving floor is fitted with side tensioners that are easily accessible. In this way, its body forms a straight channel leading the manure towards the beaters. Being wider (inside and outside) than the body, the spreading unit allows the product to expand before being ejected by the beaters.

Drawbar Suspension

All Siroko muck spreaders are standard fitted with a cross-suspension drawbar with parabolic leaves. Not only does this system offers an unmatched driving comfort, even at high speeds, but it also makes it possible to keep the traction line continuous without deformation. Thanks to this solution, the operator can drive at higher speeds (40 km/h), regardless of the terrain conditions.

Running Gear

The oversized axle of the Siroko is bolted under the monocoque body. Since the axle can be moved, it allows a perfect balance with sufficient weight on the eyelet, regardless of the tyre configuration. This assembly and an assembly with wheels with a larger diameter are therefore made possible without having to touch the hydraulic motor of the moving floor or other elements. The eyelet is also bolted and can therefore be changed at any time without having to modify the structural elements. All Siroko muck spreaders are standard fitted with double-circuit air brakes. However, it is possible to get hydraulic or dual brakes as an option.

Spreading and Beaters

The spreading width of the Siroko usually varies from 7 to 12 m, depending on the products to be spread. To achieve it, the two vertical beaters rotate at a speed of 423 rpm and project the material by means of the bolted HARDOX 450 teeth (70 x 10 mm, except on model S4008: 50 x 8 mm). Under the beaters are two retractable blades which, in addition to projecting the material, also act as a smashing hammer. The flow per hectare is adjusted easily by combining the speed of the tractor with that of the moving floor (thanks to the potentiometer within reach of the cab). In this regard, a galvanised guillotine door (option) can also help. The beaters are driven on the tractor side by a Walterscheid P.T.O.-shaft with shear bolt security. The shaft drives the gearbox at 1,000 rpm, to which the two beaters are coupled. The spreading unit is very high and ensures an easy passage and crumbling of any potential dome of material in the body.
