Dando and Furukawa Rock Drill

Dando Drilling is the UK representative for Furukawa Rock Drill.  The Japanese rig and equipment manufacturer has a pedigree stretching back almost as far as that of Dando with the company starting in 1875 following the opening of the Kusakura Copper Mine. This was followed by a manufacturing facility opening in 1900 to build their own mining equipment and, when the demand from other mines for their products was identified, the company was split into three divisions with the Furukawa Rock Drill Company beginning to sell worldwide. Since then, the division has gone from strength to strength with over 35,000 crawler and Jumbo drills being produced from their two manufacturing facilities.
