Liebherr has announced the introduction of the 470 EC-B flat-top, the largest crane in its Tough Ones series.
The flagship crane, equipped with intelligent assistance systems, offers a jib length of 80 metres. Its reach can be increased to 83 metres by means of a jib extension, breaking new ground in the market.
With a jib length of 80 metres, the 16-tonne version of the 470 EC-B has a jib head load capacity of up to 3,200 kg. The 20-tonne version delivers a jib head load capacity of up to 3,000 kg. The jib can be divided into two-and-a-half metre sections so it can be adapted to meet a variety of operational requirements.
During development of the flat-top crane, Liebherr focused on performance as well as assembly and transport. As a result, the jib and counter-jib can be attached to the slewing platform easily and safely. Liebherr’s quick assembly connections make it all possible. According to Liebherr, five trucks are needed to transport the slewing part with jib, including counter-ballast, to the construction site.
The 470 EC-B features a connection for both 24 HC 420 and 24 HC 630 tower systems. The 24 HC tower system is an ideal match for large cranes with high lifting capacities. Its compact dimensions allow individual elements to be moved cost-efficiently from A to B.
The 470 EC-B has been optimized for the 24 HC 420 tower system; together they are a cost-effective combination for freestanding hook heights of up to 67.8 metres. The maximum freestanding hook height of up to 96 metres is achieved with the 24 HC 630 system.
The top-slewing crane is available with one of three versions of the LiCAB crane operator’s cab: LiCAB Basic, LiCAB Air or LiCAB AirPlus. All three offer a floor space of more than two square metres, an unrestricted view for precision lifting and an ergonomic control stand. The features enable the crane operator to stay focused on the job at hand. Thanks to the cab’s extensive field of vision, the crane operator has a clear view of the site and its load, which contributes to the safety of both operator and machine.
Also included in the cab is the newly developed 30-cm display screen with intuitive operability.
The Tower Crane Operating System (TC-OS) provides crane operators and assembly engineers with specific menus, languages options and user-friendly units of measurement. The intention is every user should be able to find the parameters relevant to their work without difficulty. Users navigate their way through the streamlined menu structure via touchscreen. To maintain an overview during crane operation or scaling, display masks can be combined in various ways. The usability of the TC-OS means that training and familiarization times are reduced.
LED advertising space
LED advertising panel lighting can be configured to ensure a substantial long-distance effect and visibility, particularly at the onset of twilight and at night. With a total area of 8.6 square metres, the lighting delivers effective promotional impact. The panels don’t have to be mounted separately during assembly and can remain in place on the counter-jib end section during transport. Signage is easily applied.
As they don’t have a tower head structure, several EC-B series Flat-Top cranes are able to work together safely on the same site, even in tight conditions. EC-B cranes are specifically designed to meet the requirements of modern construction sites. They cover a wide performance spectrum, ranging from small city to large handling cranes. The new 470 EC-B completes the top end of Liebherr’s successful series, with the crane reflecting the construction industry’s trend towards ever heavier components.
