Spreader A2Rs (H) 5220.55

The spreader was designed to dump a massive leach pad in the irregular deep valleys close to the Toquepala pit. The upstream feeding equipment consists of an extendable and relocateable belt conveyor with a mobile head station on crawlers, a 60 m wheel driven Grasshopper and a 150 m long mobile conveyor bridge. The spreaders total length of 160 m guarantees a wide range of dumping before the upstream equipment needs to be relocated. The spreaders superstructure can be leveled against the crawler undercarriage to dump steep ramps. The 95 m long spreader intermediate bridge is supported on the spreaders superstructure and on a second double crawler for a total independent operation of the spreader.
