Uralmashplant shipped casting crane 500 100/20 m for the Cherepovets Metallurgical Plant (JSC "Severstal").

The project is designed crane NGO "VNIIPTMASH." The crane is mounted in the oxygen-converter shop and is designed to transport buckets with liquid iron to the converters.

According to Engineering Corporation, the new crane is identical to the other two put "Severstal" in 2009 These cranes belong to a new generation of materials handling equipmentValves are equipped with variable speed drive with recovery (return) brake energy network.

Machines are operated in dusty conditions and high temperatures, so benefit from enhanced "persistence" of the equipment. To protect against heat prompted additional shielding metal. To the same end cabinets with control equipment housed in air-conditioned containers, compressor parts air conditioners rendered in the "cold" part of the crane — far away from the converter.

The design of the crane Uralmashzavod implemented several non-standard solutions. Among them — a full backup drives the basic mechanisms of the crane. So, if fails one of the four engines of the main hoist, crane provide long-term operation of the remaining three engine off if one of the transformers — can only work on the second, each of the two active rectifier can ensure the operation of all drives. In addition, the Uralmash cranes provided a deeper diagnosis of the drives and systems. Modern information system also provides load control — the main 500-ton lifting weight measuring system is equipped with the transmission of information about the lifted load by radio dispatcher shop.
