Double trolley overhead cranes are usually used for heavy-duty lifting. Applications are usually in steel mills, ports, construction sites, and manufacturing plants. The materials handled are often steel coils, containers, machinery, etc.
At Yuantai, we know that there is no "one size fits all" in the lifting field. Universal cranes are suitable for general occasions, such as factories, warehouses, etc.
European overhead cranes are further upgraded in technology and are suitable for working conditions that need smaller crane structures, high positioning accuracy, and low noise.
Besides, different applications have different needs for cranes. So, we provide customized cranes according to the special needs of our customers. For example, steel and machinery industries often lift billets, steel plates, and other magnetic items, so need electromagnetic overhead cranes. Ports and docks often need to load ore, gravel, and other bulk goods, so need grab bucket cranes. Chemical and other dangerous places often need to carry flammable and explosive materials, so need explosion proof cranes. In short, you need to choose a suitable crane according to your actual situation.
