PRODUCTS & CASES

QY Insulation Overhead Crane is a specialized lifting solution developed for non-ferrous metal electrolytic smelting plants and other industrial environments with electrical hazards. It is mainly designed for electrolysis workshops in industries such as aluminum, magnesium, zinc, lead, and other metal processing fields.

With lifting capacities ranging from 5 tons, 10 tons, 16 tons, 16/3.2 tons, 20/5 tons, and other customized specifications, this insulated bridge crane provides safe and reliable material handling under electrically conductive working conditions.

Since electrolytic workshops typically operate with high-current DC equipment, the crane is equipped with multiple insulation protection systems installed at critical structural and electrical connection points. These insulation measures effectively prevent current transmission from lifted materials to the crane structure, reducing the risk of electric shock and ensuring safe operation for operators and equipment.

Designed for high-temperature, high-humidity, and corrosive industrial environments, QY insulated overhead cranes provide reliable lifting performance and enhanced safety protection for modern electrolysis production lines.

QY Insulation Overhead Crane is specially designed for workplaces where electrical isolation is required, especially in industries involving conductive materials and energized equipment.
