African Mining Delegation Explores Advanced Hoist Control Solutions

A delegation of mining executives from Africa recently visited our hoist manufacturing facility in Northern China, where Sales Manager Sabrina He showcased our latest frequency control cabinet for mining hoists. 

The tour highlighted the cabinet’s role in enhancing safety and efficiency in underground operations, aligning with global mining automation trends.

Key Technical Features Demonstrated:

• Precision Control & Efficiency

The cabinet enables semi-automatic or manual operation, ensuring smooth hoist starts, runs, decelerations, and stops. Its PLC-based control circuit offers flexible programming and minimal maintenance, while air circuit breakers and high-performance inverters reduce noise and energy consumption by up to 30%.

• Robust Safety Protections

Dual redundant safety circuits (software + hardware) instantly trigger emergency braking for critical faults like overspeed or direction errors. Integrated photoelectric encoders provide digital monitoring of speed/position, with safeguards against loose ropes, derailments, and depth indicator failures.

• Smart Monitoring & Diagnostics

Real-time touchscreen displays show operational parameters, fault records, and dynamic process visualizations. This allows operators to diagnose issues rapidly—such as abnormal vibrations or temperature spikes—reducing downtime by 40%.

• Automated Safety Signals

The system auto-generates position-based alerts for deceleration, over-winding, and emergency stops, syncing with hoist movement to prevent accidents.

A mine operations director noted, "The backup protections and remote diagnostics solve our biggest challenges: minimizing unplanned stops and ensuring worker safety."

Our factor' s R&D team emphasized customization for African mining conditions, including dust resistance and voltage stability features. Sabrina further highlighted post-sales support, with 24/7 troubleshooting via embedded monitoring data.
