Power and automation technology supplier ABB reported that it was awarded a contract to supply a mine hoist system to the Zarya mine of Kryvbaszalizrudkom JSC in Ukraine. The hoist will lift ore from a depth of 1,717 m in 50-ton skips at a speed of 12 m/s.

The order consists of a complete mine hoist system with hydraulic disc brakes, two 3,700-MW overhung synchronous motors and an ACS6000 MV drive inverter, power transformers, medium and low voltage switchgears, and a System 800xA control and monitoring control system incorporating underground control equipment, shaft alarm, an operator control panel, and a combined operator and engineering station.

A complete ABB mine hoist system including mechanical, electric drive and control equipment has been in operation at Zarya since 1960 without any modifications. “This is not the first time we have chosen ABB equipment,” said Fedir Karamanyts, CEO of JSC Kryvbaszalizrudkom. “In 2010, the plant started to use a modern electric drive, a control and monitoring system, as well as disc brakes supplied by ABB with the hoist installed at the Lenin mine. With the launch of this hoist system, the plant is now able to hoist barren rock by increasing payload capacity to 35 tons and the speed to 14 m/s, while lowering hoisting energy consumption.”

ABB’s Swedish branch will be the main contractor for the project, with certain portions of the project conducted by ABB’s local engineering and service centers in Ukraine as well as with ABB Ukrainian business partners.
