Dakar, Senegal
A 450t Manitowoc 2250 crawler crane worked on the construction of one of the largest mineral sand mines in the world in the sand dunes of Senegal. The crane, which is the largest in Senegal, performed lifts and carries at the $570m Grande Côte Mineral Sands Project, north of Dakar.
The 2250, fitted with a MAX-ER capacity-enhancing attachment, was bought by Grande Côte Operations, the main contractor and mine operator. The machine’s main tasks included installing the dredge, surge bin and pontoons that would form part of the mineral processing plant. Each pontoon weighed 120t and measured 29m long, 5m wide and 4.5m high. The surge bin was a 225t unit that has already been installed. The lift was completed in three sections, with the largest weighing 87t and measuring 22m in radius.
Situated on a mobile dune system, the 400 km2 site presented a number of challenges for the crane, among was sand and searing heat.
To contend with these rugged conditions, the crane was regularly maintained and cleaned.
The Manitowoc 2250 was transported to Senegal from the US. It was shipped to Dakar and transported 145 km north to the coastal site on 29 truckloads.
