Brian Perry used the Potain Igo 50 self-erecting crane to replace the foundations of three large caustic storage tanks at a chemical processing plant in Tauranga, New Zealand.
Manitowoc said that the 4t capacity Igo 50 was erected between the tanks and lifted materials and equipment over a 2m tall perimeter wall, which encloses the hazardous area. Each tank was also suspended 4m off the ground by a temporary steel frame.
Manitowoc’s New Zealand dealer Tidd Ross Todd supplied the Igo 50 to contractor Brian Perry Civil for the six-month job, as well as the 300t Grove GMK6300L used to place the Igo 50 between the tanks. Once in position, the team used the crane’s remote control to hoist the loads.
Ben Ackerman, project engineer at Brian Perry Civil said: "With no way of accessing the site other than through the air, we needed a crane with a small enough footprint and precise load control to carefully maneuver loads around the job site."
The Igo 50 is the largest self-erecting crane in Potain’s Igo range. It has a 40m jib and can lift 1.1 t at the jib end. Manitowoc said it has been designed with a small rear slewing radius to ensure maneuverability on congested job sites.
