Mammoet moves heavy items, including a 1,300-tonne crusher, across a copper mine in Chile.
Chilean state-owned copper mining company Codelco commissioned Dutch heavy lift and transport specialist Mammoet to move crusher parts a distance of 4.5km across a mine near the city of Calama. Route-planning for the job took a
year-and-a-half due to its complexity. In total 16 components needed to be
moved, six of which were very large. These were nicknamed ‘the big six’ – with the heaviest items being a 1,100-tonne silo and a 1,300-tonne crusher. The crusher was the most complex of the big six to move, says Mammoet, and required the reinforcement of a support beam to prevent deformation. The main methodology used for lifting and moving the big six was to lift using
climbing jacks and move using SPMTs with support beams, although the exact approach was tailored for each component; some items, for example, also needed to be skidded out of/into position. The crusher also required rotation whilst on route to its new location.
The whole operation took just over a
month (faster than expected) and utilised a team of 70 people, and a total of 160 axle lines of SPMT, eight skid shoes (500t), eight jacking systems (400t), as well as support beams, rails, and lashings. It required Mammoet to pool its global
resources: SPMTs from Malaysia, skidding systems from the USA, and additional equipment from Colombia were all utilised across the scope of the project.
