Mammoet moved a 690-metric-ton (mt) granite rock crusher and primary conveyor inside the A.R. Wilson Quarry in Aromas, California, USA. Both pieces of equipment needed to be relocated from the top of the quarry to the new location downhill and 1,200 meters (m) away.
Owner Graniterock previously attempted to drive the rock crusher, Mammoet reported. The crusher experienced a loss of braking power and the operation could not be completed safely. Mammoet proposed to move the crusher in one piece on SPMTs and received the contract.
