A well-known ductile iron precision component manufacturing enterprise purchased two casting bridge cranes from our company in 2002 for the transportation of molten cast iron materials in the casting workshop. Ductile iron is a cast iron material with properties equivalent to steel. The enterprise uses this material to produce high-strength walking parts for use in the construction and agricultural machinery manufacturing industries. These two cranes can still be used normally after 16 years of use. But with the continuous growth of the user's demand for professional casting technology, the iron ladle that needs to be transported can load up to 3 tons of molten material, exceeding the load capacity of existing cranes. The user is well aware of SEVENCRANE's extensive experience in designing cranes for this type of process, and has therefore approached us again. We replaced the 50.5-meter-long crane track in the casting workshop and installed two new casting bridge cranes, increasing the rated load capacity to 10 tons.
These two brand new casting cranes meet the special requirements specified in EN 14492-2 standard to ensure the normal operation of casting cranes under extreme environmental conditions. The new casting crane is still used in its casting workshop to transport molten iron packages with temperatures around 1500 ° C. The crane transfers it from the melting furnace to the pouring truck, which then sends the material to the casting line. There, high-quality ductile iron material is filled into the mold and the process of casting the blank after completing its quenching process. The bridge cranes in these two casting workshops are based on mature universal crane technology and designed non-standard, fully meeting the strict requirements of the user's casting workshop work.
SEVENCRANE worked closely with the user and dismantled the old crane during the factory rest period. Afterwards, new crane tracks and cranes were installed, and the power supply was also updated and structurally modified. At the same time, the pouring method will be upgraded from manual pouring with a handwheel to electric pouring. After the user's brief vacation, the employees in their casting workshop can now use a new crane to work. These new casting cranes use durable crane components that can run smoothly from the beginning. We have once again demonstrated to the user the reliability, safety, and efficiency of our crane under harsh conditions.
