Feature
Life-Saving Safety Systems
• Dual braking (automatic disc + mechanical failsafe) with ≤0.1m emergency stop distance
• Load-sensing overload protection (150% capacity cutoff) and anti-slack rope technology
Corrosion-Resistant Construction
• 316L stainless steel drum guard withstands 10,000+ salt spray hours (ASTM B117)
• PTFE hoses and marine-grade epoxy coating for offshore/chemical exposure
Precision Control
• Variable-speed radial piston motor (0-20 m/min adjustable ascent/descent)
• Grooved drum with press roller ensures ±5mm wire rope alignment accuracy
Product Description
The Ingersoll Rand MR150 Man Rider® Air Winch sets the global benchmark for personnel hoisting safety. Certified for 150 kg personnel loads with 10:1 safety factor, this winch is deployed in critical vertical access scenarios:
• Oil & Gas: Derrick basket transfers (API 4F compliance)
• Wind Energy: Turbine nacelle crew lifts (EN 12385 Class 8)
• Mining: Shaft inspection team deployments (MSHA Part 77.1900)
Key engineering highlights include stainless steel braided control lines (5x abrasion resistance vs. standard hoses) and dual limit switches preventing over-travel beyond preset 0-100m zones. The lift-to-shift lever enables ±2% speed accuracy for delicate positioning. As an authorized Ingersoll Rand distributor, KRC provides on-site safety audits and OEM-certified spare kits for MR150 winches.
