Energy is transmitted via an electrified rail system. Chile state-owned copper miner Codelco said on Thursday it will pilot Caterpillar’s (NYSE: CAT) new Dynamic Energy Transfer (DET) system, which supplies electricity to both diesel-electric and battery-electric large mining trucks while in motion. The trial will take place at Codelco’s Radomiro Tomic Division in northern Chile using three Cat 798 AC diesel-electric haul trucks. One-year trialThe one-year trial will involve installing electrified rails along a ramp in open-pit operations. Marc Cameron, Caterpillar’s senior vice-president, said the collaboration would help refine DET’s design by incorporating customer feedback.
