OPERATION TO SECURE THE CRANE AND REMOVE THE BOOM DAMAGED FOLLOWING AN INCIDENT.
The Solutions et Services teams worked in inclement weather on a crane with a lifting capacity of 150 tonnes at Brest's commercial port. This crane, built by Joseph Paris in 1979, is over 80 metres high and weighs more than 1,300 tonnes.

A delicate operation
The operation involved making the crane safe and removing the boom and cables damaged following an incident.
The work was carried out after an initial diagnostic phase, and a stability study phase for the crane.
This particularly complex operation involved calculating the centre of gravity of the various components during each phase of the operation, to ensure that the crane would not tip over.
Similarly, each crane used for handling was scrupulously positioned according to the calculations of our design office, and the locations were marked out on the site.
The crane was moved to a position suitable for dismantling, the jib was placed on the ground and the counterweight was adjusted to make the crane perfectly stable.
This operation involved 4 cranes (1 70-tonne crane, 2 220-tonne cranes, 1 300-tonne crane). Around twenty people were on site (handling teams, mechanics, electrical engineers, site manager, safety manager, etc.).
Our expertise in building this crane, and our ability to carry out stability studies, enabled us to carry out this operation in complete safety for both the structure and the people involved.
This operation demonstrates the expertise of the Solutions and Services teams at Etablissement JOSEPH PARIS and the Fayat Lifting Solution division.
