FIELD: construction, namely apparatus or processes for treating or working the shaped articles, particularly for high-quality treatment of non-hardened concrete surfaces made of rigid concrete mixes used in civil and industrial building.
SUBSTANCE: multiroll smoothing working tool comprises two end sprockets with rolls eccentrically installed on the sprockets. The rolls may rotate and oscillate in vertical direction by means of planetary gear. The planetary gear includes central tooth-wheel and pinions to be brought into engagement with the tooth-wheel.
EFFECT: decreased vibration transfer to machine frame, enhanced smoothness and compaction of concrete and asphalt-concrete surfaces.
