In a joint venture project of Vialy Vives SA and Sigdo Koppers SA, a workshop for maintenance of dump trucks and a concentrator station on a Chilean copper ore mine are currently being built. The construction is supported by a Liebherr crawler crane, type LR 1300.
Situated in Caserones, southeast of Copiapo, at altitudes between 4,200 m to 4,600 m above sea level, the mine is owned by SCM Minera Lumina Copper Chile. When completed this year, it will process around 105,000 t per day of primary and secondary copper ore extracted from an open pit mine.
The LR 1300 is used for construction and assembly works; one of the main tasks of the high-performing crawler crane is the structural, electromechanical, mechanical and electric assembly of a concentrator station, used for processing ore. In total, approximately 20.000 t of metal constructions, 14.000 t of mechanical equipment, 70.000 m of piping with different diameters and 150.000 m of cable and circuits for electro- and control technology are required for this enormous jobsite. Construction work is planned to be completed after 24 months and approximately five million man-hours.
These numbers demand the operation of a crawler crane with outstanding performance attributes, such as the LR 1300. Due to its high output, full power, mobility and multifunctionality this crane is very well suited to execute this job.
