German company Steil-Kranarbeiten has completed construction work on a hotel that remained open thanks to its Liebherr LTM 1150-5.3.
Completing work on the Schlossberg Hotel in Homburg, Germany, the company needed to ensure that access to the hotel for guests, suppliers, and emergency vehicles was guaranteed at all times. To complete this, the company enlisted the services of its Liebherr LTM 1150-5.3.
The mobile crane features a capacity of 150 metric tonnes, holds a telescopic boom of 66m, an extendable, fold-out lattice jib of up to 26m, and a maximum working radius of 72m. At the jobsite, Steil-Kranarbeiten needed to work across a 65m radius and navigate 17th century tunnels residing under the site – hence the decision to use the compact, long-reaching Liebherr LTM 1150-5.3, according to Frank Nicklas, head of Steil’s Saarwellingen branch.
“With the LTM 1150-5.3, we have exactly the right mobile crane that can meet these requirements with its large radius, while also leaving enough space for hotel guests and delivery vehicles,” he said.
Around 150 lifts were completed over a period of two weeks, and the radius challenges were overcome by deploying the fixed double folding jib angled at 40 degrees and the 66m boom almost fully extended. Steel girders weighing up to one tonne hung from the crane hook and were installed on the other side of the hotel complex. Precise load handling by the crane driver was essential, as most of the construction elements were mounted in a suspended position.
As part of the complexities of allowing access to the hotel, the need to position the crane to allow for sufficient space was imperative. Nicklas, discussing the features of the Liebherr mobile crane, said there was “no chance” the operation would have been completed without Liebherr’s patented VarioBase.
“Without the options that VarioBase® offers us, we wouldn’t have been able to complete the job in this format,” he said. “We would have had another 160-tonne mobile crane from another manufacturer available, but we couldn’t have set it up under these conditions because of the less convenient outriggers.”
