NKMZ PJSC has started manufacturing of a unique overhead ore double grab car reloader for Azovstal Iron & Steel Works.
In recent years, NKMZ has manufactured, shipped and installed several coal grab reloaders for coal warehouses, including for Azovstal, as well as one ore reloader for the ore stock yard of PJSC Zaporizhstal.
“The uniqueness of the new reloader is provided by several characteristics,” says Sergey Martynenkov, deputy chief designer of chief designer department of the mining and press-forging equipment division at NKMZ. – These are gigantic dimensions: the span or the distance between the supports is 115 m with a total length of the beams of 185 m, the height is 49.7 m. It also has a significant weight – 2400 tons. But its main advantage is high productivity, which is achieved by the presence of two grab cars moving independently of each other. They will ensure a total capacity of this machine – 800 t / h. On the previous NKMZ reloaders, only one grab car was used.
The contract for the manufacture of this reloader was signed by NKMZ with Metinvest in 2019. The active phase of its production began in March this year. As of today, the necessary design and technological documentation has been issued for production. The production of a rigid support for the reloader and a mechanism for its movement, which includes 24 gearboxes, 96 traveling wheels and a system of balancing bogies, is already in progress.
The beginning of the installation of the reloader at the Azovstal Iron & Steel Works is scheduled at the end of this year, and commissioning – at the end of the next year. ”
