Hammtronic is an electronic machine management system that monitors and controls all key machine functions. It supports controlled machine operation, efficient performance, and demand-based fuel consumption. One of the functions of Hammtronic is the automatic adjustment of the diesel engine speed to the power requirements of the individual drives. In addition, Hammtronic controls acceleration and deceleration and distributes the drive torques to the drum axle or the rear wheels based on current operating data. The hydrostatic vibration drive is also regulated by Hammtronic. Furthermore, the various steering programs (DV+ series only) are controlled to ensure smooth and uniform movement of both drums.
