INTRODUCTION

The QC Electromagnetic Overhead Crane is a double-girder bridge crane equipped with a detachable electromagnetic spreader (magnetic chuck/beam). Driven by an electric current to generate a powerful magnetic field, it seamlessly attracts, lifts, and releases magnetic metal materials.

APPLICATION SCENARIO

Petrochemical & Chemical: Lifting in hazardous areas with explosive gases or solvents.
Military & Ammunition Depots: Safe handling of explosives and hazardous materials.
Paint & Coating Plants: Operating in environments with flammable vapors.
Dust-Explosive Industries: Grain mills, flour plants, and pharmaceutical cleanrooms.
Coal Processing: Safe lifting in areas with methane gas and coal dust.

ADVANTAGES

Comprehensive Explosion-proof Design: All critical components (motors, hoists, control boxes) use flameproof enclosures (ExdIIBT4/IICT4) to isolate internal sparks.
Space-Saving Suspension Structure: Runs on overhead I-beam tracks without floor columns, maximizing valuable floor space and fitting low-headroom workshops.
Lower Construction Cost: The lightweight design reduces wheel pressure on the building structure, lowering initial building costs.
Flexible Track Layout: Supports straight or curved tracks, and multiple cranes can share the same track system.
Smooth & Safe: Anti-static materials prevent static sparks, with smooth starting/braking to minimize impact and noise.
