Empty runs cannot always be avoided with semitrailer dumpers in the construction industry, which is why a low empty weight is crucial in addition to a high payload. At just 5,100 kilograms in the basic version, the Light Basic three-axle semitrailer with steel body is a real lightweight.
The Greenline version is also particularly efficient: with a height of only 1,450 millimeters, the body is lower than the driver's cab and thus ensures low air resistance, as do the lightweight aluminum rims and the lightweight frame with patented curved front end. Of course, the SAF disc brake axles are laser-measured and optimally adjusted, which reduces rolling resistance and contributes to low fuel consumption.
The side panels of the payload-optimized 24.5-m3 round body are made of 4-millimeter-thick wear-resistant steel; the floor is 4 millimeters thick in the front area and 5 millimeters thick in the higher-load dumping zone. Thanks to the conical shape - the trough is 8 centimeters wider at the rear than at the front - no cargo gets stuck. This is also ensured by the absolutely smooth surface without stops in the rear area. Even without an additional seal, the curved membrane flap is almost completely leak-proof, and moist bulk material remains in the trough. A metering device is recessed in the rear wall of the fair vehicle; the double-jointed hinge offers a very large opening angle, which facilitates tipping.
All supply connections as well as shovel and broom are easily accessible at the front of the vehicle. After unhitching, standard cross braces on the 24-ton two-speed support winch ensure stability. Until the next use, the hydraulic hose is parked in its holder and does not lie on the ground - this keeps the coupling clean. When loading from the side with the wheel loader, bulk material always goes astray, but thanks to the integrated and stone-repellent mudguards, it falls immediately to the ground and is not transported onto the road.
Like every vehicle from Fliegl, the DHKS 390 StoneMaster light also offers well thought-out details, which above all ensure the longevity of the tipper trailer: for example, the upper belt is made particularly robust, it consists of a double steel layer. If the excavator or wheel loader should ever bump into it during loading, the trough remains in shape - expensive repairs are no longer necessary. The tarpaulin fastening has also been developed to meet practical requirements: Fliegl does not use the usual rope rings, which quickly bend; instead, the rope is hooked into special recesses in the outer wall of the skip. The tarpaulin trays are also well protected on the inside of the skip. Should there ever be any collision damage, the hooked-in holders can be replaced in a flash - without welding, without tools.
In addition to efficiency, safety is also a top priority at Fliegl. That's why the patented Drive-on system is on board. It reduces rolling movements and the risk of the trailer tipping over on uneven ground when the body is upright. For this purpose, two fold-out metal supports establish a connection between the last axle and the frame during tipping; after lowering, the supports spring back to their original position. The system, which weighs only 26 kilograms, works purely mechanically and also offers a starting aid.
On the three-axle truck, the first axle can also be raised, which means that 2.8 metric tons of the semitrailer's weight is transferred to the fifth-wheel plate when it is tipped, thus ensuring greater stability. For moving off with a load, as much as 6.7 tons press on the drive axle - resulting in more traction on loose ground. From a speed of 25 km/h, the axle automatically lowers again. Since the drive-on system means that the air bellows are no longer fully compressed, the rubber blocks inside last much longer. The same applies to the arms of the air spring mounts, which are located at the lowest point and are permanently exposed to dirt and moisture. Fliegl is therefore the only manufacturer to galvanize the air spring arms and offers a 10-year anti-rust guarantee.
Fliegl does not skimp on light either: the comprehensive LED package consists of multi-chamber taillights with dynamic turn signals, side marker lights as well as position and lane departure lights. Two LED worklights integrated at the rear ensure optimum illumination when maneuvering.
