Specialized Winder Fitters, Electricians, or Rigger manage the ultimate lifeline of a mine: the winder system. The winder (or mine hoist) is the massive mechanical and electrical drum system used to transport personnel, heavy machinery, rock, and explosives between the surface and deep underground shafts.
Core Areas of Experience & Skills
-
Mechanical Maintenance (Winder Fitters): Experience includes inspecting and replacing heavy components like winder ropes, gears, bearings, and heavy-duty braking systems. [1, 2]
-
Electrical & Automation (Winder Electricians/Technicians): Involves working on high-voltage AC/DC drives, closed-loop control systems, transformers, and electronic speed controllers to ensure smooth ascent and descent. [1, 2]
-
Hydraulic Systems & Safety Interlocks: Winders rely on complex hydraulic braking setups. Artisans must have extensive experience in hydraulic fault-finding, reading schematic drawings, and testing safety circuits. [1, 2]
- Legal Compliance & Inspections: Mining laws dictate rigorous daily, weekly, and monthly testing. Experience includes certifying critical failsafes like over-wind and under-wind trips, emergency arresting devices, and slack-rope protections
