The Sakai HV80ST is a heavy-duty, walk-behind (pedestrian) duplex vibratory roller designed for compacting soil and asphalt. While often referred to in the 760–780 kg weight class, it is highly regarded for its “all-drum drive” hydrostatic system which provides excellent traction on slopes and uneven terrain.
Below are the detailed specifications for the Sakai HV80ST:
