Out of the many kinds of equipment installed by the specialists of Yuzhmormontazh, STS, RMG, RTG container and grab-type transfer cranes hold a special place. It is caused by the structural complexity of those kinds of cranes, their overall dimensions, weight characteristics and equipment necessary for assembly operations. Limited time and work space provided for assembling and repairing the transfer cranes result in creating new techniques for installing such complex equipment. Solutions and technologies used by the company's specialists reduce the assembly time and allow to avoid using heavy-weight erecting cranes. As a result, the installation costs and performance time are greatly reduced. We have great experience in installing, dismantling and repairing bolted and welded metal structures of cranes manufactured by such companies as Azovmash, Mariupol heavy engineering plant, Alexandria plant "Vira-Service", NKMZ, SKMZ, TAKRAF, Sibtyazhmash, Fantuzzi-Reggiane, KONE, EDERER, Hartman, KOCKS, LIEBHERR. The availability of skilful and experienced staff as well as a wide range of truck cranes with lifting capacity up to 180 tons, allows Yuzhmormontazh to install the container and grab-type loaders of different manufacturers in compliance with customers’ and manufacturers’ requirements.
