Successful replacement

New track for coke plant charging machine  

 

  • Five mobile cranes were needed for the replacement work

  • A total of 50 employees were involved

  • Before being transported away, the old tracks had to be cut into pieces

Perfect teamwork enabled the tracks for the coke oven battery at Hüttenwerke Krupp-Mannesmann (HKM) in Duisburg-Hüttenheim to be replaced in record time.


Coke is baked around the clock here, producing more than one million tons per year. 

A key step in coke production is the charging of the 70 ovens. Two charging machines operate day and night. They travel backwards and forwards along the top of the battery on two fixed tracks, filling the oven chambers with coal through openings in the oven roof. To ensure that oven charging continues smoothly in the future, the 140 meter long tracks were successfully replaced in March. The installation took almost twelve hours and involved 50 employees from the equipment technology unit along with site manager Michael Lindtner from thyssenkrupp MillServices & Systems.

“The biggest challenge was to replace the two tracks during the roughly ten hour break in pushing operations. We managed to get everything finished on schedule.”

A total of five mobile cranes (2 x 400 tons, 2 x 250 tons and 1 x 160 tons) and three mobile gantry cranes (3 x 5 tons) were needed to install the new tracks, each weighing approx. 67 tons. “The biggest challenge was to replace the two tracks during the roughly ten hour break in pushing operations. We managed to get everything finished on schedule,” said Alexander Jäger, project manager from the equipment technology (crane technology) unit.

However, before the new tracks could be installed, the old ones had to be cut into pieces in preparation for being transported away. “That was an important initial step in fitting the new tracks,” said Jäger, adding: “All in all, the replacement went really smoothly. The entire team did a great job, especially as temperatures on the oven roof were over 50° Celsius. So I’d like to thank the whole team and Thomas Trepmann (Hüttenwerke Krupp-Mannesmann project manager) and Ralf Keller from Wasel (Duisburg branch manager, responsible for directing mobile crane operations).”
