INVT provides a fully variable-frequency digital hoisting system, which focuses on solving key pain points of mine hoisting in terms of safety, energy consumption and intelligence, achieving intrinsic safety in transportation and intelligent operation and maintenance.
Risk of out-of-control operation: Slow response of old electric control systems and brake failure may easily cause runaway.
Energy efficiency waste: Resistance speed regulation features high energy consumption, and start-stop shocks damage equipment.
Maintenance difficulties: Frequent mechanical failures lead to low efficiency in troubleshooting during shutdowns.
Data silos: No monitoring of operating status, resulting in no basis for decision-making.
"Safety Assured · Intelligent Energy Efficiency Control"—— A reliable, efficient and intelligent hoisting system built through multi-dimensional redundant design and adaptive control.
