INVT monorail crane realizes precise speed regulation and zero-speed hovering under heavy load in underground mines, eliminates derailment risks, improves material transportation continuity, and enhances equipment turnover efficiency at fully mechanized mining faces.
Positioning Drift: Traditional hydraulic drive has small positioning errors, requiring frequent adjustment during equipment installation.
Heavy-duty Rolling: Hydraulic lock failure during slope start-stop causes cargo sliding accidents.
Complex Maintenance: Hydraulic system oil leakage pollutes roadways, requiring monthly downtime maintenance.
Low Energy Efficiency: Motors still run at full speed under no-load / light-load, resulting in excessive power waste.
Drive Logic: Real-time correction based on laser ranging and inclination sensing; dual-loop vector control achieves millimeter-level positioning.
Safety Redundancy: Electromagnetic brake linked with VFD zero-speed full torque; heavy-duty hovering angle > 30°.
Energy Efficiency Management: Automatically reduces frequency to 15Hz under light load; no-load standby power consumption < 5%.
