At first glance, this project didn’t look particularly challenging, but when taking into account all the jobsite restrictions, crane service provider Schmidbauer realised that it needed to execute a high-precision masterpiece. Stacking-containerised offices can be an everyday task, but when this is carried out indoors and with minimum space to maneuver, it’s another thing. For this job, Schmidbauer used a crane that is globally known to work in tight spaces — the Terex AC 40 City crane.
In addition to the lack of space, the project held another challenge: in order not to disturb the production work at the logistics warehouse, all lifts would have to be carried out during a single Saturday. This is where the Terex AC 40 City crane’s ease of mobilisation and fast assembly proved to be invaluable. The team was able to drive the crane to the jobsite and set it up in just 30 minutes.
The mission was to stack 16 containers inside the building. To be able to perform the lifts despite the lack of space, the Schmidbauer team mounted a runner with the maximum possible off-set directly on the crane’s main boom. In addition, they forewent a hoist rope and used swivel hooks instead. This made it possible for the AC 40 City to literally put the 6-metre long, 2.5-tonne containers in chains at all four corners and then lift them using a radius of about 10 metres. “With this configuration, I was able to bring the upper containers to the required height and then set them down on the lower ones without running into the ceiling structure or into any lighting fixtures or pipes,” said crane operator Steffen Jaenecke.
