SITE SHOWCASE Ӏ TOWER CRANES
division of Manitowoc that provides custom-engineered tower crane solutions for challenging and large-scale projects. This was the first time that a
Potain crane equipped with frequency inverter drives has been mounted on a travelling gantry.
This integration delivers smooth, stepless motion along the tracks and excellent lifting performance, says Potain. It also offers onboard assistance, particularly when paired with Potain’s Connect digital platform for real-time
remote diagnostics, machine operation alerts, and remote actions. The MD 689 25 was set up with permanent double reeving, providing a maximum lift capacity of 25t when the jib is at 26m, and 7.6t when the jib is extended to its maximum of 75m. For its working location the crane was treated with paint to withstand the highly corrosive portside environment meeting the C5-H standard under ISO 12944. Other customisations included specially designed access and dedicated
lighting. This features a lighting system operated from the control station that can be dimmed to avoid interfering with ground operations. There are also work cameras on
the trolley and portal, as well as a communications system featuring in-cab microphones and speakers, an external loudspeaker, and channel encryption. The new crane has been operating at
the port’s naval maintenance and repair quay since March, replacing a crane that had been in operation since 1960.
