French maritime company Nantes Saint-Nazaire Port has taken delivery of a custom built 25 tonne Potain MD 689 M25 tower crane installed on a new type of travelling portal base.
The tower crane assembled on the tracks
The crane, replaces one that had been in operation since 1960, and has has been installed with permanent double reeving, providing a maximum capacity of 25 tonnes at 26 metres and 7.6 tonnes at the 75 metre jib tip, with a hook height of around 60 metres. The portal base interfaces directly with the Potain Crane Control System in order to travel along 170 metres of rails, covering all three of the port's dry docks.
The travelling base is the first on a Potain crane equipped with frequency inverter drives, which are integrated into the CCS, to deliver smooth motion along the rails. The crane was also treated with a special paint to withstand the corrosive port side environment and features custom designed access and lighting.
Potain business project manager Sylvain Brunet said: "Lifting operations in ports have always been dynamic and demanding, with very high economic stakes. For Nantes Saint-Nazaire Port, the requirements of the industry and the needs of our customers led us to develop a more robust and innovative solution."
