The most important parameters when designing the new 125 HC-L 6/12 Litronic were the requirements of operations at great heights and on the most constricted construction sites. Hence, for example, its exceptionally tight 6.8m slewing radius, Liebherr said.
Maximum load capacity is 12t, and it can lift 1.9t to 30m jib-end, although the jib can vary in length from 30m-50m.
As an alternative to the standard 256 HC tower system, the 125 HC-L 6/12 Litronic is available with a newly developed 200 IC internal climbing tower system, which has a 1.6m x 1.6m tower cross-section, which has a maximum height of 44m.
The 125 HC-L 6/12 Litronic has a maximum lifting capacity of 12,000 kg and a maximum radius of 50m. As an optional extra, Liebherr also offers teleservice applications for this crane type, enabling remote diagnoses using satellite communication for example.
When moving the jib, a programmable logic controller monitors the hoist gear automatically ensure that the load hook travels along a horizontal path. This is a significant advantage in erecting or concreting operations especially.
This new luffing jib crane comes exclusively with stepless FC drives. The standard equipment also includes 45kW FC hoist gear, 45kW FC luffing gear with secondary brake and two 5kW FC slewing gear systems. As an optional extra, the FC hoist gear and FC luffing gear can be fitted with more powerful motors, producing 65kW each. For operations on very tall buildings, hoist gears enabling hook heights with single-reeved ropes of up to 978 m are also available. In this configuration, the load hook moves at up to 190 m/min.
The new 200 IC internal climbing tower comprises 5.8m-high tower sections. The climbing hydraulics are all located inside the tower sections and is designed for easy disassembly.
The entire crane system is designed to be transported in 40- foot standard containers. The transport volumes can be kept low by nesting the jib sections inside the 256 HC tower. The slewing platform can be divided in two. No single component weighs over five tonnes.
