Construction 18, 20, 22, 26 Ton Single Drum Frequency and Amplitude Modulation Vibratory Roller
This roller is offered at 18, 20, 22 and 26 tonnes with frequency and amplitude modulation. Variable frequency and amplitude is the significant feature: rather than switching between two fixed settings, the machine adjusts its vibration to the stiffness of the layer beneath it. That matters on mixed fill, where a setting that compacts one section will over-compact and loosen the next. Weight class and control configuration are specified at order and built to the tender schedule.
