The 180 HC-L 8/16 Litronic is a new luffing jib tower crane from Liebherr in Germany. The 16 tonner is a development of and a replacement for the 160 HC-L. A new feature is higher lifting capacity across the full torque range. The articulation point has been moved further outwards and jib-end load is higher than the outgoing model. At maximum working radius of 55 metres capacity is 2.6 tonnes.
Important parameters in the design of the new crane included practical requirements for rapid load handling at height on confined construction sites. Operation on restrictecd sites is helped by a rear slewing radius of 7 m. It can be mounted on the 1.9 x 1.9 m 355 IC climbing tower system, which can be outside a building or inside a small lift shaft. Above 60 m the 500 HC mast system can be used for a freestanding height of 64.9 m.
Frequency controlled stepless drives are a standard feature, including the 65 kW hoist gear, 45 kW luffing gear unit with secondary brake, and two slewing gears rated at 7.5 kW. More powerful motors are available – 110 kW for hoisting and 65 kW for luffing. For operation on very tall buildings, a hoist system is available for hook height up to 874 m, travelling at up to 338 m/min.
