The QY Series Insulating Overhead Crane is engineered for specialized applications in electrolysis processes and metallurgical workshops handling non-ferrous metals, such as aluminum and magnesium. Its design prioritizes operational safety in environments where electrical conductivity poses a risk. The crane’s structure integrates a robust box-type frame, a reliable crane traveling mechanism, a high-performance trolley, and advanced electrical systems.
To safeguard operators, the crane incorporates a multi-layer insulation system that effectively blocks electrical currents from transmitted loads. Built for heavy-duty cycles, it adheres to stringent safety standards, featuring dual braking systems on the main hoist for enhanced operational security.
Key Insulation Components:
Insulated hook and pulley assembly
Insulation between the lifting system and trolley frame
Insulation barrier connecting the trolley frame to the crane bridge
Each insulation component maintains a resistance value ≥1MΩ under standard conditions (20–25°C, ≤85% humidity)
