They are commonly used for specialized operations such as lifting molten steel and handling billets in steel mills. Equipped with specialized high temperature slings and protective systems, they are highly versatile and easy to operate. Explosion proof double girder electric overhead cranes: Utilizing explosion proof motors, electrical components, and a sealed design, they are suitable for hazardous environments where flammable and explosive gases or dust are present, such as chemical plants and oil and gas storage areas, effectively preventing spark induced accidents.
Double Girder Electromagnetic EOT Cranes：Equipped with electromagnetic chucks, these cranes attract magnetic materials like steel and steel plates when powered on and release them upon power failure, eliminating the need for manual lashing. Widely used in steel warehouses, machine shops, and scrap yards, they efficiently handle bulk steel or scrap, minimizing the risk of spillage.
double girder Explosion proof overhead crane: Utilizing explosion-proof motors, electrical components, and a sealed design, all spark-generating components are explosion-proof. They can operate safely in hazardous environments with flammable and explosive gases and dust, effectively preventing explosion risks associated with equipment operation and ensuring stable handling of heavy loads in high-risk environments.
Double Girder Grab Bucket overhead crane: Equipped with a hydraulically or mechanically driven grab mechanism, they automatically grab and unload bulk materials by opening and closing the grab, eliminating the need for manual assistance. Suitable for use in ports, mines, waste treatment plants, and other locations, they can efficiently handle bulk materials such as ore, coal, sand and gravel, and construction waste, significantly improving bulk cargo loading and unloading efficiency and reducing labor costs.
Double Girder EOT Crane is a robust, smooth-running, high-capacity lifting device widely used in factories, warehouses, steel structure manufacturing, and large-scale engineering projects. It offers significant advantages including high efficiency, precision, and safety reliability.
