Fast offboard systems are ideal for trucks in continuous operation with limited idle time, while slow onboard systems suit stationary equipment like drill rigs.
These flexible solutions are built on open standards, ensuring they can be used by all vendors and are adaptable to specific mine designs, layouts and operational use cases.
Innovations in underground trolley system testing ABB highlights trolley-assist systems as a dynamic charging solution, feeding power into diesel-electric trucks through overhead lines.
ABB collaborated with Epiroc to deploy the first fully battery-electric trolley truck system on an underground test track for Boliden. This system has since been extended to a 5km segment, bringing the industry closer to the allelectric mine of the future.
Energy is recovered through regenerative braking on downhill sections. New trolley systems are being designed for full re-locatability, featuring modular pre-cast foundations and lightweight suspension systems.
Automation and electrification are mutually beneficial, with control platforms integrating power and process control to manage variable loads.
ABB says that automated energy management systems analyse operational schedules in real time, allocating power where it is needed.
