Sommer and Spallek lift with Liebherr

first_imgThe demolition team had just two nights to remove the concrete supports and the railway track beneath the bridge was shut to traffic for two days.  The 300-tonne capacity Liebherr mobile cranes were positioned on both sides of a railway track approximately 8 m below the bridge. The cranes’ attachment equipment was secured to each half of the 80-tonne concrete supports, which measured 2 m in height, before work began to cut the supports in the centre and at the abutments using a diamond-tipped wall saw.  The crane drivers then had to work with precision to ensure that the freely suspended sections of the support, measuring around 15 m in length, did not tilt. The project was made more challenging due to adverse weather conditions, including sub-zero temperatures and thick fog at the site. According to Liebherr, Sommer-Kranverleih from Bremen and Autokrane-Spallek from Ibbenbüren, Germany, have fleets that comprise of approximately a dozen cranes each, all of which have been supplied by the Liebherr plant in Ehingen.     www.liebherr.com www.sommer-kranverleih.de www.autokrane-spallek.delast_img
