If plant protection products could be used sparingly, it would reduce costs in agriculture and benefit the environment. Herbert Dammann GmbH has developed a large-volume, high-precision Tridem crop protection sprayer. This means the agricultural vehicle only spreads as much material as necessary - and as little as possible.
The technology saves up to 70 per cent of herbicides
Comfortable driving and low wear
Technologically speaking, the Tridem crop protection sprayer comes with several innovations from the Dammann company. The herbicide concentrate is mixed with water to create a spray solution. It always needs to be well mixed and the components optimally integrated. DAMMANN has developed the ‘rotating mix and cleaning machine’ for this, known by the German abbreviation RRW. It is attached in a barrel and consists of several stirring nozzles which continuously turn in the barrel and thereby keep the liquid moving. The RRW also means the inside of the barrel can also be easily cleaned after removing the solution, which is all the more important in a container of this size.
As in the tandem spray, there is an axle relief installed which ensures that there is always sufficient support on the K80 bearings and the drawbar trailer axle, even in difficult conditions. This ensures comfortable driving and reduces wear on the materials. The Tridem can also save time – through its size alone. If used optimally, it can replace other machines and thereby also reduce the number of personnel required.
Joint driving trial with BPW
The vehicle is equipped with three pneumatic BPW axles and hydraulic drawbar suspension. BPW was chosen in particular because quality was of the highest priority for the DAMMANN: the square axle beam with reinforced axle cross section of the BPW products, the KTL coating, the BPW wheel bearing system and the BPW brake cam shaft with the spherical bearings of the pneumatic axle make them extremely robust but at the same time smooth-running – and all these advantages mean an extremely long life expectancy.
Bergische Achsen KG and Dammann have already enjoyed a trusted collaboration for many years. In the context of new EU requirements for devices which spray crop protection products, the new homologation of the tandem field spray recently became necessary: “The vehicle had to go through various tests in order to demonstrate that it fulfilled all the conditions of the corresponding regulation,” explained Frank Rothe, Area Sales Manager Customised Solutions at BPW Bergische Achsen KG. “We were happy to support Dammann with the practical driving trial here, which included braking tests, among other things. The results were perfect.”
