Jama manufactures the Rock breaker RB80

Jama is now completing the first unit of an order of 3 Rock breakers to LKAB in Kiruna. The machine is operated from a control room above ground and has a weight over 40 tonnes. It is equipped with a 4-tonne hydraulic breaker that breaks the rocks that are too big to pass the grizzly with openings of 0.5 * 0.5 m.

We at Jama are very pleased that after a number of years of product development with extensive field tests and in tough competition, deliver these machines to LKAB.
