Atlas Copco (China) Investment Company, an offshoot of Atlas Copco AB, has signed a contract to acquire assets of rock drilling manufacturer Shenyang Rock Drilling Machinery for an undisclosed amount.

The Chinese equipment manufacturer, which already had a tie-up with Atlas-Copco to import and distribute rock drilling equipment, is based in Shenyang City, Liaoning province in north-east China, and generated a turnover last year of more than US$12M.
