Tight lift for Toggenburger
By Laura Hatton07 August 2014
Swiss crane service provider Toggenburger used a Terex Challenger 3180 and a Terex AC 100/4L all terrain crane to install a 60 metre long pipe at a paper mill in Perlen, Switzerland.
The 60 tonne capacity Challenger 3180 has a 50 metre boom, which can be extended with a 16 m extension. It has a 12.1 tonne counterweight and lifts 37.9 tonnes at 4 m radius. The 100 tonne Terex AC 100/4L all terrain has a 59.4 m telescopic main and is powered by a 335 kW engine.
The job was carried out for main contractor Caliqua, based in Basel. The paper mill is next to a railway line and a busy road, making the job challenging due to time constraints. André Huber, project manager, said, “It was all down to speed and precision on this job to avoid blocking the rail traffic, as well as the 40 trucks a day supplying the paper mill, for an unnecessarily long period of time. Our two Terex cranes delivered on both counts.”
To lift the pipe into position the cranes were configured with 35 m booms and standard outrigger configurations. The 24 tonne pipe was supported at four points and lifted at a working radius of 15 m and to a height of 15 m.
It took three hours to set up, complete the lift and then disassemble the cranes, a spokesperson added.
