In mining operations, material transport and personnel lifting in vertical and inclined shafts are critical to production efficiency and operational safety. Traditional hoisting systems often face three major challenges:
● Poor adaptability to complex working conditions
● Insufficient safety redundancy
● Low energy conversion efficiency
Wanfeng Machinery’s JTK/JTP/JK/JKMD series mining hoists address these challenges through innovative design.
● Angle adaptability: Full coverage from 0-90° (vertical/inclined shafts)
● Dual-mode design: Single-drum & double-drum configurations
● Three-speed control: Resistance / frequency conversion / explosion-proof frequency conversion options
① Dual braking system: Electromagnetic + manual mechanical braking
② Intelligent overspeed protection: Auto-trigger at 10% excess speed
③ Wire rope monitoring: Real-time tension feedback
④ Anti-fall device: Compliant with standards
⑤ Emergency power supply: Continuous braking for 30 minutes after power failure
● S7-1200 PLC control core
● Response time <50ms
● Speed control accuracy ±0.1m/s
● Supports remote monitoring (4G/5G/WiFi)
● Working conditions: 16-25° inclined mining tunnels
● Transport capacity: Customizable per client requirements
●
● Working depth: 100-3000m
