COAL MINING:
Trolley-Assist Pantograph Transformer Line

PRODUCT: IP54-3900kVA

APPLICATION: Coal Mining

THE CHALLENGE

 
Open cast mine hauling activities have a high cost impact in terms of diesel usage. Output may also be considerably lower if these activities are carried out by diesel-only powered trucks. But if the trucks are designed to use both diesel and electric power, a trolley-assist power line can be applied to mine hauling activities.

By applying trolley-assist, mine hauling activities can save up to 50% in fuel cost, and improve the productivity of the fleet by 10% or more.

THE SOLUTION

 
We provided a trolley-assist solution to one of South Africa’s largest diversified resource groups. The truck automatically switches to electric mode when it detects and attaches to the overhead line powered by a pantograph transformer. And once the truck leaves the line, it switches back to diesel.
