The emergency services were called to a tower crane that had started to list in Hamburg, Germany yesterday.
The crane operator was lifting a couple of sheets of re-bar on the surprisingly untidy site in the Lokstedt area of the city, when the crane tower shifted. He immediately stopped everything and called the fire and rescue service before climbing down from his cab.
The emergency services found that one of the corner blocks that the freestanding counter-weighted crane was sitting on, had shifted. They evacuated around 100 people from the surrounding buildings and then placed wooden blocks/cribbing under the frame and used a slim hydraulic jack to apply pressure and stabilize the crane while the owner was notified.
A mobile crane quickly arrived on the scene to remove the load and possibly start dismantling the crane. Thankfully winds were exceptionally light and so were not a factor.
