World’s highest situated and deepest Alima kelevators at the world’s largest gold mine

Grasberg Mine, Irian Jaya, Indonesia, Indonesia

The Alimak elevators at the Grasberg mine, Indonesia beats several records. They are both the highest situated and the deepest Alimak elevators ever installed. The Grasberg mine is the world’s largest gold mine and the highest situated mine in the world.

The Freeport-owned Grasberg mine in Papua province, Indonesia, is the world’s largest gold mine, the third largest copper mine and the highest mine in the world. The workings include a very large open pit mine, an underground mine and four concentrators. The open pit mine — which forms a mile-wide crater at the surface — is a high-volume, low-cost operation, producing more than 67 million tons of ore. When they needed to install an inspection shaft down to a level of 640 meters below the surface, the best solution they could find was the Alimak rack and pinion elevator. Installed in 1997, the elevators has operated faultless despite the extreme conditions.

The two Alimak U-600 elevators give access for service and maintenance and emergency access in a vertical inspection raise at a lifting height of 640 meters each. These two elevators are both the highest situated — at an altitude of about 4,200 meters above sea level — and the deepest with 640 meters lifting height.

Two additional Alimak U-600 elevators was installed to give the operators access to the two crusher stations with 27 meters lifting height. Besides the four Alimak elevators, five Champion US elevators have been installed at the mine operations mobile crushers, in shafts and towers.
