The underground mining environment features high humidity and heavy dust, requiring winch equipment with high durability and low failure rate.
Fluctuating local power grid voltage posed risks to the stable operation of electrical control systems.
Complete certification and test documents were required for local customs clearance and mine safety inspection.
The client required simple on-site installation and quick commissioning after delivery.

Enhanced Environmental Adaptability: Adopted thickened sealing design for motors and reducers to achieve excellent dustproof and moistureproof performance, adapting to harsh underground mining conditions.
Stable Electric Control System: Added surge protection devices to the electric cabinet to effectively solve the problem of local voltage fluctuation and ensure continuous stable operation.
Complete Export Documentation: Provided full set of official documents including CE certificate, factory load test report, material certificate, packing list, commercial invoice and proforma invoice to support smooth customs clearance.
Strict Factory Testing: All winches passed 1.25 times rated static load test and dynamic load test before delivery to eliminate potential safety hazards.
Professional Technical Support: Equipped with English version installation & operation manual, and provided remote online technical guidance for on-site installation and commissioning.

Production Cycle: 20 working days
Shipping Cycle: 30 days from China to Durban Port
Acceptance: All equipment passed on-site load inspection and safety acceptance at one time
Operating Effect: The winches run stably without rope jamming, overheating or failure. The overall on-site lifting and handling efficiency increased by 30%.
Repurchase: The client placed a repeat order of 2 sets of 10-ton electric winches within half a year, recognizing our product quality and after-sales service.
