TOWER CRANES Ӏ FIBRE ROPE
exterior of the rope is made up
of multicoloured braided material. A rigger or specialist can easily spot abrasion in this. When the red core is visible the rope should be discarded but still maintains 100% of its lifting capacity. Liebherr has been
demonstrating its confidence in its fibre rope, with a programme called Fibre Care. Prices for the service start at €50 a month. As well as offering support for
users, they come with a six year guarantee that Liebherr will make up any difference between the costs of replacing a steel rope, and those of replacing a fibre rope. For users worried about training and cost, this should help ease their transition away from steel wire rope. Another sign of Liebherr’s confidence in the technology came at Bauma, when the company demonstrated tower cranes with fibre rope across its range. The new 1188 EC-H high-top
is the largest standard crane in Liebherr’s range. Launched in Munich, it can lift 13.1t at the end
Tower crane usage monitoring
London,UK-based software company 1Guava has launched its tower crane usage monitoring program in the UK. 1Guava says the program can increase on-site productivity, promote proactive scheduling, and deliver intuitive reporting to support on-site operations by capturing vital utilisation data on-site while capturing key events such as winding off, maintenance/ breakdowns and idle time. 1Guava launched the program at the Vertikal Days trade show in the UK where it gave demonstrations of the software's capabilities in real-time.
Luffers, typically used at high hook height, stand to benefi t from the use of fi bre rope. Liebherr launched its fi rst fi bre luffer at Bauma
of an 80m jib, and has a maximum capacity of 40t. Liebherr says that this helps demonstrate the benefits available when using fibre rather than steel.
RECORD-BREAKING CAPACITY The fibre crane lifts 2.1t more at 80m, than is available on Libherr’s next largest crane, the 1000 EC-H, with steel wire rope. The new crane also lifts further, with the option of extending the jib to 90m, 10m longer than on the steel rope crane. “The 1188 EC-H 40 is our
first high-top crane with fibre rope technology,” says Markus Kinateder, product manager, Liebherr-Werk Biberach. “We’ve increased the performance capacity of our EC-H series even further with this crane and can now offer our customers even greater

support for the implementation of large and custom projects,” Cranes like this are used
for some of the biggest civil engineering projects: they’re suitable for pouring large volumes of concrete on dams, for example, or for handling other building materials across large sites. Increases in capacity, achieved through using fibre rope, should have a real impact on these large, long term, projects.
LUFFING WITH FIBRE The benefits of fibre rope can be seen lower down the capacity scale. At Bauma, Liebherr showed its first luffer with fibre rope for hoisting (Liebherr and Wolffkran have both experimented with the use of similar materials for luffing pendants, on tower cranes and on crawlers; these, like the rope,
