LIEBHERR LAuNCHES FLAGSHIP FLAT-ToP


Liebherr has launched the 470 EC-B Flat-Top crane as a flagship model in its ‘Tough Ones’ EC-B series. The crane is available in two versions – with 16 or 20 tonne lifting capacities – making it the largest in the series line-up, with the cranes utilising a steel rope design. The 470 EC-B has a jib length of 80


metres which can be increased to 83 metres via a jib extension. At 80 metres, the 16-tonne model has a jib head load capacity of up to 3.2 tonnes, while the 20-tonne version has a jib head load capacity of up to three tonnes. The jib can be divided into two-and-a- half metre sections.


The crane has been designed with ease


of transport and assembly in mind, said Liebherr, with quick connections for jib attachment. Only five trucks are required to transport the slewing part with jib, including counter-ballast. The 470 EC-B has a connection for


both 24 HC 420 and 24 HC 630 tower systems. The 24 HC tower system is a perfect match for large cranes with


high lifting capacities, said Liebherr, and its compact dimensions allow the cost-effective transportation of individual elements. Together they are the most cost-effective combination for freestanding hook heights of up to 67.8 metres, Liebherr added. Using the 24 HC 630 system a


maximum freestanding hook height of up to 96 metres can be achieved. The top-slewing crane is available with one of three versions of Liebherr’s LiCAB crane operator’s cab: LiCAB Basic; LiCAB Air; or LiCAB AirPlus. All have over two square metres floor space, an unrestricted view, and an ergonomic control stand, said Liebherr. Also included is a new 12” display


screen via which the crane operator can access the Tower Crane Operating System (TC-OS). This touchscreen system provides users with specific menus, a choice of languages and user-friendly units of measurement. To maintain an overview during crane operation or scaling, display masks can


be combined in various ways. The crane incorporates LED lighting


for advertising. The lights cover an area of 8.6 square metres, for high-visibility promotional purposes. The advertising panels can remain in place on the counter-jib end section during transport. The absence of a tower head structure means several EC-B series flat-top cranes can work together safely on the same site, even in tight conditions, said Liebherr. The new 470 EC-B completes the top end of Liebherr’s series, with the crane reflecting the construction industry’s trend towards ever heavier components.


CRANE PLANNER SoFTWARE uPDATED


Liebherr has launched an updated version of its Crane Planner lift planning software which includes new crane models and tech features. It now incorporates: Liebherr LTM


1650-8.1, LTM 1450-8.1, LTM 1300-6.2, LTM 1250-5.1 and LTM 1230-5.1 mobile cranes; all Liebherr crawler cranes with lifting capacities up to 300 tonnes; as well as hydraulic rope excavators. Additional telescopic mobile cranes


are being added to Crane Planner 2.0 at regular intervals, said Liebherr, with the LTM 1350-6.1 being the first of these to be added.


The updated program includes a new distance tool which enables objects, such as machines and buildings, to be positioned relative to each other with centimetre precision, said Liebherr. Crane Planner 2.0 combines an

interactive 3D visualisation of the machines, the loads and surrounding objects with dimensions, a positioning tool and Google Maps, without the need for expensive CAD programs or high performance computers, Liebherr explained. The results of the planning


process can be exported in the form of a report and sent to the customer, enabling even small crane contractors can compete for large tenders. Existing users of Liebherr’s Crane


Planner lift planning software can update to the latest version for free.
