Liebherr’s newhydraulic luffing jib crane, the NC-LH 12-55, excels in large cities andis optimised for countries outside Europe. With a minimal working radius ofjust three metres and an out-of-work position of ten metres, thecrane can be optimally adapted to inner-city construction site conditions.

Liebherr isexpanding its product range with its new hydraulic luffing jib crane. The hydraulicluffing jib crane combines the familiar performance of Liebherr luffing jibswith powerful hydraulics in a crane package that is specifically geared tomarket requirements outside Europe.

The result is atop-slewing crane, for large cities in countries as diverse as Australia,Thailand, and the United Arab Emirates, that can be positioned centrally onsite. Together with its high lifting capacity of up to twelve tonnes andthe ability to lift 2,450 kilograms at its jib head, this complete packagemakes the NC-LH 12-55 a unique machine.

“We provide asetup that’s strong in all aspects, from transport and assembly through tooperation, and can offer our customers an outstanding overall concept for theirsites,” says Markus Kinateder, Product Manager at Liebherr-WerkBiberach GmbH.

Developed for use in densely built-up inner-city areas

TheNC-LH 12-55 can be optimally adapted to everyday conditions on site andrequires very little space. This adaptability is achieved through being able toinstall the crane in lift shafts, its reduced out-of-service position, andminimal swing radius, and the fact that the cabin is mountable on either side.

A lift shaftinstallation with subsequent internal climbing is no problem at all using the16 EC 240 tower system. So, the crane can be centrally positioned onsite where it can lift up to 2,450 kilograms at its jib head at maximum radius.

Its minimalworking radius of just three metres also helps to ensure that all areas on sitecan be covered from a central point. In practical terms, this means that asmaller crane can be used on site rather than a larger machine that would needto be set up next to the building.

Another optionalongside the slim 16 EC 240 is the widely used 21 HC 290tower system, which enables high hook heights and installation of theEasyUp 200 crane driver elevator. Both tower systems come prepared forclimbing inside and outside buildings. Combining both systems together with atransition tower section makes it possible to achieve cost-efficient, hightower heights.

Anotheradvantage is that cranes can be positioned closer together when several need tobe used on site. This allows more cranes to fit into the available space as andwhen required.

A reducedout-of-service position of ten metres for jibs 45 metres or longermakes it all possible. The jib can be extended in five metre increments. Atmaximum tower height, the out-of-service position measures up to14.6 metres.

Thought has alsobeen given to tight spaces in terms of the crane’s swing radius: thecounter-jib has a swing radius of just 7.9 metres and its ballast blocksare stackable.

The cabin can bemounted on either the left or right-hand side to meet individual siterequirements and building proximity needs. It is possible to position the cranecloser to the building this way, which gives the crane operator a better viewof the load and surrounding environment.

Designed with transport in mind

Transporting thecrane into the city and through inner-city environments is designed to be asconvenient and simple as possible. Four trucks or containers are enough totransport the NC-LH to its next job location.

With the jibwidth being just 1.15 metres, three sections fit onto a standard truck or inone container. And, length isn’t a problem either: the jib end section can beslid into the counter-jib, and all platforms and rails can stay attached to thecounter-jib indefinitely.

The hoist unitis also ready installed on the jib, meaning it stays in place during transportand is also protected. This all saves assembly time.

The slewingplatform and central unit can either be lifted onto the truck pre-assembled orpart by part ready for individual assembly steps. The choice depends on whichmobile crane is available for the later assembly of the components, which canweigh up to eight tonnes.

A smaller mobilecrane can be used for lifting component assemblies, while a more powerfulmobile crane is capable of handling the pre-assembled jib and counter-jib unitin a single lift to save time.

The crane’s jibcan be completely pre-assembled on the ground. Even the hoist rope and hookblock can be revved ready for use so that working at great height isn’trequired. This saves a lot of time and is also much safer than assembly uphigh.

Designed for efficient working

Liebherr’sluffing jib cranes are ideal partners for sites involving heavy components andhigh hook heights. Hydraulic luffing jibs score extra points with theirpowerful hydraulic unit and cylinder combination, and precision load positioning.

The luffingsystem enables fast and precise luffing in under 90 seconds. Plus, the jib canbe adjusted safely and at controlled speed with a load on its hook.

Load-Plus is nowavailable for luffing jibs thanks to the launch of the new crane. A load increaseof up to 26 per cent can be achieved at the touch of a button forparticularly heavy one-off lifts.

TheNC-LH 12-55 also comes equipped with the new Tower Crane OS operatingsystem. An easy-to-view menu bar ensures quick navigation and the user interfacecan be customised to suit different users.
