Modernization of the power plant in Ostrava, which is part of Třebovice, is currently underway.
This coal-fired power plant has been a source of heat and electricity in the region since 1933 and at one time was one of the largest in Central Europe.
We used a Liebherr 250EC-B Litronic tower crane with a maximum load capacity of 12 tons to replace the important filter technologies of the power plant.
The tower crane was delivered to our partner - MROZEK a.s. and its assembly was carried out using a mobile crane from its own fleet.
Since the chimney of one of the main boilers is located in the rotation zone of the tower crane, it was necessary to ensure the prevention of collision of the boom with the chimney during work and outside of working hours.
The Litronic control system made it possible to set a so-called circular section, which does not allow the arm to turn into the zone of a possible collision with the chimney when the crane is working.
Outside of working hours, the crane is anchored with a two-arm rope anchor to the prescribed anchor points.
