Its boom can be further extended by a variety of jib and boom configurations, enabling a maximum hook height of 120 metres and a radius of up to 94 metres. These capabilities make the 300-tonne model particularly well suited for tower crane erection and wind turbine maintenance. Southern Cranes specified the unit with an 11.5 to 20 metre double swing-away fly jib, which can be offset hydraulically by up to 40 degrees. With the addition of a seven-metre boom extension between the boom nose and jib, the crane can achieve a 92-metre hook height and a 72-metre radius. Director of Southern Cranes & Access, Kelvin Prince said, "The addition of these two Liebherr cranes represents a significant investment in the continued growth of our business.
