Dockside crane lift in France
Mediaco Maxilift lifted the tower of a dockside crane from its base at a French port to make it possible to perform necessary maintenance work. In order to safely lift the 414 tonne (456 U.S. ton) load and then place it back on its base, the company relied on a Terex CC 2800 lattice boom crawler crane.
The two lifts brought several challenges for the Mediaco team. First, the wharf’s structure was not designed to bear the joint weight of the CC 2800 and its load.
“In order not to damage the structure, we placed steel beams under the CC 2800’s crawler tracks to better distribute the weight,” said Mediaco Maxilift project manager Robert Titart.
Additionally, the load’s centre of gravity proved an obstacle. A custom-made spreader was used to balance the load with the required precision. However, the spreader added 11.5 tonnes to the load being lifted, increasing the total weight to 433 tonnes together with the 4.5-tonne hook block and the 3-tonne rigging cables and chains.
Mediaco set up the CC 2800 with an SSL configuration, a 54m main boom, a superstructure counterweight of 160 tonnes and a Superlift counterweight of 300 tonnes and decided to use a Superlift radius of 15m. With this configuration, the CC 2800 was prepared to safely lift the load and put it back down later within the required working radius of 16m.
