The technnology for sensitive rolling: TanGO

TanGO (tangential oscillation) compacts risk-free e.g. on seams (hot to cold), on bridges or near buildings. And even better, TanGO is simple to operate: it comes with only one amplitude, which is optimised for all applications. BOMAG tandem rollers with TanGO always compact with care. The drum cannot bounce, because TanGO always works obliquely to the surface. This has two advantages: on one hand there is no crushing of aggregate; on the other hand no bow waves are created, even when working at higher working speeds. The TanGO drum is in the rear of the machine, so the front vibrating drum can be used for thicker layers or stiffer mixes. TanGO compaction uses two exciter shafts rotating in the same direction, so that a torque is generated around the drum axis. The drum quickly keeps alternating its effective direction tangentially to the contact surface (forwards and backwards). The mat is actually compacted with double frequency.
