Tandem roller Single drum compactor and compared? General Characteristics It has a single wheel vibration roller in hand, compared to a single drum compactor exciting force greater climbing ability. Construction who is the best roller Walk behind compactor Tandem roller technical parameters: Model walks SYL-S600 Power 6.0hp / 3600rpm, speed 0-4km / h (forward, backward) Fuel tank capacity 3.6L, theoretical gradeability 30% Lubricant volume 0.6L, compacted fuel consumption 313g / kWh, static linear load 45N / cm, the nominal amplitude of 0.6mm drum width 600mm X2, the vibration frequency of 70Hz drum diameter 430mm, exciting force 20KN total length (flat armrests) 1420mm, water tank capacity 15L Overall width 750mm, working Overall height (armrest raised) 1100mm, Drive: compact hydraulic drive unit package size 1050x900x1200mm walk-behind double drum vibratory roller structure, small size, easy conversion venue. Product Principle Features ①, large water tanks to reduce the trouble of back and forth, so that the device can continuously increase the working time. ②, hydraulic forward and backward walking, mechanical vibration with reliable performance. ③, automatic clamping of polyurethane automatic cleaning scraper to prevent dirt and asphalt gathered in the drum, make compaction more smoothly on the drum. ④, vertical vibration exciting force, high compaction efficiency. ⑤, adjustable folding operating handle to the operator with a comfortable operating environment, folded for easy transport or collection.
