Russian crane distributor JSC GRPM has completed lifting work at a federal power station in Saint Petersburg, Russia, after collaborating with Terex Cranes' applications team to provide a bespoke solution.
Main contractor OAO Metrostroy awarded JSC GRPM the contract to supply crane support for the construction of a new 120m-diameter cooling tower as part of upgrade works at the nearly 40-year old facility.
As the cooling tower needed to be built to a height of 150m, this presented some unique complications for set-up of the Terex Comedil CTT 331-16 tower crane selected for the job.
Firstly, the standard free-standing height for the CTT 331-16 tower crane is only 92.6m. So for this particular job, high resilience steels adapted for operation at low temperatures were used in each tower section to increase the maximum set-up height to 158.6m.
