Liebherr has unveiled its next generation luffing jib crane, hailing the 440 HC-L as a response to ever faster construction site cycles.

Following on from the 357 HC-L, the new release comes with improved performance values and is available in two versions: the 440 HC-L 12/24 and the 18/36.

The maximum lifting capacity of the 440 HC-L 18/36 is 36 tonnes. It has also been possible to raise the tower height of both crane versions by one tower section compared to the previous model.

Liebherr said the 440 HC-L required very little space for a crane of its size. An out-of-service position of up to 10.7m or a minimum working radius of less than 4m is possible.

In practical terms, this means that the crane can be set up closer to buildings, property boundaries or another luffing jib crane, which makes site planning easier.

Depending on the situation, the out-of-service position makes it possible to accommodate and operate an additional crane on site.

The 440 HC-L’s maximum radius is 65m and the jib can be extended in 5m increments.

The OEM said this was the first time aramid fibre guying was being used for a luffing jib crane.

‘The lightweight material reduces weight on the jib, resulting in a higher lifting capacity. Significant weight is saved compared to the use of steel ropes; dead load can consequently be transformed into load capacity,’ Liebherr said.

‘An aramid fibre guying system also offers advantages for crane assembly and disassembly owing to its lighter weight. Aramid fibre has already proven itself and become an established material with other Liebherr Group cranes, including crawler and maritime cranes.’

The luffing jib crane is available with the latest TC-OS control unit for simple crane operation.
