At LB CRANES, we continue to take on challenging projects. We have recently completed the installation of our second bridge crane on Line 9 of the Barcelona metro, a project that required a high degree of technical precision and careful planning.
It is a bridge crane with a capacity of 5 tonnes and a span of 25.8 metres, specially designed to operate in a completely circular structure, allowing it to rotate 360 degrees. This design meets the specific needs of the underground space where it is located.
A highly complex technical installation
The biggest challenge of the project was the installation of the equipment, which was carried out in an 80-metre-deep well. This was compounded by additional complications, such as the sloping ceiling and a sharp reduction in diameter at the bottom of the shaft. These conditions required a highly complex installation manoeuvre, carried out through the synchronised coordination of two cranes, which operated in a continuous sequence of movements to adjust both the inclination and position of the bridge crane until it was precisely aligned with the rail beams.
Structural solutions tailored to the project
Another notable feature of this project was the need to adapt the support system due to the particular characteristics of the environment. To this end, two types of metal brackets were installed:
- Some welded to the roof of the structure, with L-shaped beams (vertical pillar and cantilever beam).
- Others are anchored directly to the walls of the well using chemical anchors, ensuring stability and strength.
These types of installations demonstrate our ability to develop customised solutions in complex environments, always complying with the highest standards of safety and efficiency.
