El AK 640 SA es el buque insignia de la serie AK y ofrece el máximo rendimiento gracias a su enorme tolva de alimentación y la tecnología de motor de última generación. Al mismo tiempo, es tan fácil de transportar como los modelos más pequeños.
The AK 640 SA is distinguished by an optimal combination of performance, efficiency and flexibility. This is ensured, among other things, by the separate drive unit for the scraper floor and floating infeed roller as well as the material infeed system which is controlled in line with machine load and which ensures the continuous shredding of material and optimum system utilization.
The feed hopper with a width of almost 6 m makes it easy to feed the AK 640 SA, even with very large, oversized material. The discharge belt, featuring a length of 7.50 m and a width of 1.50 m, impresses not only due to its discharge height of more than 5 m but also due to the fact that it can be lowered almost all the way down to the ground, ensuring very easy and quick access to the flail drum, shredding tools and rear basket.
The easy replaceability of parts and high diagnostic capability of the machine allow for great ease of servicing and maintenance.
In spite of the dimensions of the AK 640 SA when operating, it can be easily relocated by boasting transport dimensions of 12 m (length) and 2.5 m (width). The new MTU 6R 1500 diesel engine with 20 kW of more power complies with the EU Stage V emissions standards. Other features further distinguishing this high-speed shredder include its exhaust system with its completely new stainless steel piping and the highly effective shielding of its exhaust aftertreatment system with integrated insulation optimizing the machine’s fire safety.
