The project involved the installation of a 30-ton industrial overhead crane, preassembled on the ground, inside a production facility. Due to the large size of the structure and the limited height of the building, the traditional setup with two mobile cranes could not be adopted.

The initial plan envisaged placing a mobile crane outside the building and creating an opening in the roof to lower the hook inside for lifting. However, following the client’s request for a less invasive alternative, MIDLIFT designed and executed a synchronous lifting configuration using four specialized truck-mounted cranes arranged in pairs on both sides of the beam.

The client ensured the safety of electrical cabling, removed obstacles within the work area, and welded reference stops at the base of the beams to prevent chain slippage during lifting. Using two existing overhead cranes, the new one was moved into the optimal lifting position.

The four truck cranes were positioned according to the executive project to ensure safe working conditions and proper clearance from roof trusses. After connecting the chains to the hooks and extending the telescopic booms to the required length, the lifting operations began. The maneuver involved a transverse lift to overcome the runway beams and achieve the correct final positioning.
