Product Description
Product 
Insulation double girder overhead cranes are suitable for smelting workshops such as non-ferrous metal electrolytic aluminum, magnesium, lead and zinc. Because the equipment on ground in the workshop has DC current, in order to prevent the current on the equipment from being transmitted to the crane through the lifting material during working, which will endanger the life of the driver and the safety of the equipment, several insulation devices are set on the appropriate parts of the crane to ensure the safe working.
All insulation cranes are of heavy working grade, the lifting mechanism is equipped with double brakes to ensure the safe lifting.
All the operation will be realized in the cabin.
