QY model insulated overhead crane is composed with girder frame, crane travelling device, traveling trolley, special lifting device and electrical control box. Insulated overhead cranes are specialized lifting devices designed specifically for environments characterized by strong currents, high temperatures, high humidity, and dust—such as those found in the smelting of non-ferrous metals (including aluminum, magnesium, lead, and zinc) and in nuclear power plants. Their core function is to utilize a multi-stage insulation structure to prevent electrical currents from forming a closed circuit through the crane body when hoisting conductive materials (such as molten aluminum), thereby averting short circuits, electric shocks, or equipment damage.

The insulated hook bridge crane is a special lifting equipment specially designed for ‌ strong current, high-temperature and corrosive environments ‌. By setting up multiple insulation devices at key parts, it prevents current conduction from endangering the safety of personnel and equipment.

Designed for high-current, high-temperature and corrosive environments, it prevents current conduction through multi-layer insulation devices at key parts. Widely used in electrolytic aluminum and metallurgy industries for handling and maintenance of electrolytic cells, anodes and large metallurgical equipment, ensuring personnel and equipment safety

Core Applications – Overhead Insulated Crane
1.Non-Ferrous Metal Smelting – Safely handles crust breaking, anode replacement, and molten aluminum tapping in electrolytic aluminum potrooms while
2.insulation devices prevent current conduction from electrolytic cells.
3.Power Industry – Used in substations and power plants for maintenance of transformers and live electrical equipment, providing electrical isolation to prevent arc flash incidents.
4.Electronics & Semiconductor Manufacturing – Transports sensitive components in fabrication plants while preventing electrostatic discharge (ESD) and stray current damage.
5.Chemical Industry – Handles electrically charged electrodes and busbars in chlor-alkali and electrolysis plants, with corrosion-resistant materials protecting against aggressive vapors.
6.High-Risk Industrial Applications – Provides triple insulation safety barrier for operators in any environment with electrical hazards, including workshops with static electricity and live component assembly lines.
