and 620 HC-L 18/36. The
cranes offer increased performance and reduced out of service positions.
The 440 HC-L is available in
two lifting capacity versions: the 440 HC-L 12/24 and the 440 HC-L 18/36. Its bigger brother, the 620 HC-L, is equipped to tackle large scale construction projects with its 18/36 tonne lifting capacity. Both models offer fast load handling in one-fall operation, says Liebherr. This has a positive impact on construction time for building heights of 100m and higher. Quick re-reeving for two-fall operation also facilitates the lifting of heavy components. Load-Plus means lifting capacity can be increased for specific load charts. The 440 HC-L offers an increase in jib head lifting capacity of up to 1.65t (52 percent), while
the 620 HC-L achieves an increase of up to 3.25t (76 percent). Pre-assembled assemblies
reduce the time needed for setting up on site. The hoist and adjusting ropes come already mounted on the drum and the counter-ballast consists of one ballast block. A central switchgear cabinet, mechanical quick connections, and a small number of transport units help speed up assembly.
FIBRE ROPE
The crane series is the first to make use of aramid guying for luffing jib cranes. The lightweight material
reduces weight on the jib, which increases lifting capacity as weight is saved compared to steel rope. Liebherr also had two EC-B
flat-tops erected on its stand: the 520 EC-B 20 Fibre and the 240
EC-B 10 Fibre. These were also showcasing Liebherr’s latest fibre rope developments. Liebherr says its fibre rope
cranes are becoming increasingly popular around the globe. Set to boost this popularity is Liebherr’s new rope shortening option for fibre ropes which is similar to that already available as standard for steel rope versions. If a fibre rope is irreparably damaged at any point it can now be shortened and re-bonded on site. As a result, Liebherr says, fibre
rope is now more flexible to handle than its steel counterpart when it comes to rope damage. In addition, the service life of
fibre rope has been extended. As well as benefitting crane operation this has advantages in terms of warehousing times and storage logistics, Liebherr says.
