First Atlas Copco Hydraulic Compactor convinces in India

The first Atlas Copco Hydraulic Compactor HC 920 in India was successfully demonstrated to D.Y. Uppar Engineers and Contractors, Karnataka, for compaction works in a canal modernizing project.

The Sree Ramadevara Anekattu Canal, 175 km from Bangalore, was built in 1878 and is modernized at his total length of 147 km. For slope compaction one of the contractors initially used a combination of the excavator bucket and manual compaction by wooden planks. The output of 300 meters per day was considered to be too slow. The quality of the compaction was unsatisfying because the slope surface resulted uneven which demanded more consumption of concrete.
D.Y. Uppar, one of the contractors at the canal project, took the Atlas Copco Hydraulic Compactor HC 920 with a service weight of 880 kg for trials on a Komatsu PC 200-6 backhoe in their canal project. Shri. Devraj, Site Manager of D.Y. Uppar Engineers and Contractors: "With the HC 920 we are 100 % faster than before and can manage 600 meters per day. The quality of the compaction is better because the surface shows lesser undulation which saves concrete. Since compaction is even, the soil does not slide hence there is no additional concrete used to patch up."
The Atlas Copco team in India is satisfied as well: "We have sold the demonstration unit plus two more compactors to the customer and feel that we started very well into this business," said P Royston, Product Manager Construction Tools in India.
Atlas Copco launched the range of 6 hydraulic compactors at Bauma 2007. The compactors are used in trench and soil compaction applications as well as for driving sheetings and pilings and for extracting works.
