Erection, operation, and service of the cranes is being provided by Liebherr’s exclusive dealer for Peru, Agrumaq. 

The cranes are working at a height under hook of 35m.  With maximum lifting capacities of 40m, and jib end capacities of 12t in their 51.5m radius set-up, the cranes on the project are being used at two underground stations to lift and lower construction equipment into the tunnels, and to bring up earth.
