General purpose overhead crane
QY Insulated Overhead Crane
Product advantages
- The QY type insulated hook bridge crane is suitable for smelting workshops of non-ferrous metal electrolytic aluminum, magnesium, lead, zinc, etc.
- This crane is mainly composed of a bridge frame, a large vehicle operating mechanism, a small vehicle, electrical equipment, etc. In order to prevent the current on the live equipment from being transmitted to the crane through the lifted components during operation, which may endanger the life of the driver and the safety of the equipment, several insulation devices are installed at appropriate positions of the crane.
- This crane operates on a heavy-duty system.
To ensure lifting safety, the lifting mechanism is equipped with dual brakes. - All the movements and operations of the crane are completed in the driver’s cab.
Application scenarios
- Power Industry
- Installation and maintenance of high-voltage electrical equipment in substations and power plants.
- Lifting large transformers, high-voltage switchgear, reactors, and other equipment that may be live or prone to electrification.
- Electrical Manufacturing & Maintenance
- Used in motor manufacturing plants, transformer factories, and cable production workshops.
- For assembling, testing, or repairing components that may carry electrical current, reducing leakage risks.
- Rail Transit Power Supply Systems
- In metro, high-speed rail, and electrified railway substations or maintenance workshops.
- Lifting pantographs, high-voltage isolators, and power control cabinets.
- Metallurgy and Large Industrial Enterprises
- In steel plants or large factories with integrated high-voltage transmission systems.
- For transporting tools, spare parts, and equipment near energized electrical installations.
- Ports and Ship Electrical Systems
- In shipyards or port areas with high-voltage shore power supply systems.
- For hoisting ship generators, high-voltage distribution panels, and marine electrical equipment.
