Liebherr AT lifts telescopic platform from river30 September 2020
Wilden Kran – Vermietung used its Liebherr LTM 1090-4.2 to hoist a telescopic work platform out of the river in front of the 120 year old Wuppertaler suspension railway in Germany.
Such platforms are regularly deployed in the River Wupper in Wuppertal to bridges. Set up with 22.5t of ballast, the Liebherr LTM 1090-4.2 hoisted the 12.8t work platform out of the water with a radius of 15m and placed it on a low loader.
“These jobs are now fairly routine to us as we do them between 15 and 20 times a year. However, they do require extensive preparation as all work, including our crane operations, around the Wuppertaler suspension railway route requires a permit. The personnel working there must first register with the relevant department at the suspension railway and receive safety training,” said Dominik Fandrey, dispatcher and operations manager at Wilden.
In just 2.5 hours the crane project took place in the suburb of Sonnborn on the site of the Stadion am Zoo, which is almost 100 years old. It is here that the suspension railway diverts from the route of the River Wupper.
“The work platforms can easily be moved towards the bridge structures on their crawler gear as the water is only around half a metre deep, enabling the construction engineers to complete the inspections. Of course, it is not possible in heavy rain or flooding,” added Fandrey.
