modular system

The modular-element system offers much greater benefits. Good working conditions boost productivity. Modern, ergonomic cabin design and excellent operating convenience help the operator to concentrate on the task in hand – an important precondition for tower crane efficiency. Liebherr tower cranes are of modular design so that every crane can be configured to meet individual requirements. The undercarriages or bases, tower elements, adapter sections, jib segments and drivelines can be combined freely among the EC-H and EC-B crane systems. This offers decisive benefits for crane fleet operators....

The EC-H crane system. EC-H cranes in the size category from 112 metre-tonnes upwards set the standard in today’s tough construction-site conditions, either as standard EC-H cranes in FR.tronic version or as EC-H Litronic cranes, which can sustain up to 20 percent higher loads at the push of a button. The Litronic crane control system is built up from several electronic modules. The EC-H’s spacious cabin sets the standards in design and operator convenience. The large windows ensure optimum visibility. EC-H cranes can be transported inexpensively, have innovative drivelines and are fast and easy...

sembly Practical as gy technolo The EC-B crane system. The small and medium-sized EC-B cranes. Crane operators in medium-sized building projects can choose between ten small and mediumsized EC-B Flat-Top cranes from 30 mt to 130 mt in standard or FR.tronic version. These cranes are available in either 2-fall or 2/4-fall version, or exclusively in 2-fall where the FR.tronic version is concerned. On these EC-B cranes, the compact head contains the hoist gear, the slewing gear, the central switchgear and the complete slewing ring support. The trolley travel gear is housed in such a way in the jib...

Tower systems for every task. Equipment is available for a wide variety of applications: rail-going and stationary undercarriages and cruciform bases as well as tower systems. Liebherr towers for crane sizes up to 256 HC / 290 HC have tight-welded, closed corner posts and diagonal elements. The tower connections at each corner consist of two drop forgings and two heavy-duty bolts subject to tensile rather than shear loads. These zero-clearance connections are a guarantee of the Liebherr crane tower’s long life. The stationary cruciform base with foundation blocks. 8 The support spindles for rapid...

Top comfort for increased productivity. Modern cabin design. The control centre and a comfortable workplace with an unobstructed view of the load and the site are located in the full-view noise-proofed and temperature-insulated cabin. Every load can thus be positioned optimally. This ergonomic cabin is the key to safe, concentrated work and high load-handling capacity. Ergonomic controls. The controls in the full-view cabin are exceptionally convenient to use. The panels for all control functions are integrated into the seat, with a wide range of position adjustment. The EMS electronic monitoring...

Intelligent highperformance drive systems. High-performance drives from Liebherr ensure safe, quick and efficient handling of loads. Their low power consumption also has a noticeable positive effect on operating costs. All drives were developed and manufactured at the Liebherr Group’s own competence centre for drive technology in Biberach. Frequency-converter hoist gears. Liebherr top-slewing cranes feature high-performance drive systems for maximum load-handling capacity and economy. Frequency-controlled high-performance single-, 2- and 3-speed frequency-converter drive systems with various...

3Fast assembly. Compact assembly units. The design principle of Liebherr’s top-slewing cranes cuts costs when assembling them. The cruciform base can be assembled with very little effort and it is transported as two complete packages. A variety of bases is available for different applications. Completely pre-installed assembly units. Once the tower base and the climbing system have been assembled, the complete slewing platform is installed. This unit is completely pre-installed and can be transported on a normal truck. It is assembled with one lift. Once the slewing platform is installed on the...

Well-planned detail desig n makes erecting work easier. The complete jib is pre-installed on the ground. The trolley and the load hook form a single assembly unit. Reeving and tensioning the trolley rope is fast and easy without connection to the mains, since the drum can be rotated freely with the brake released. Fast hoist rope reeving. The hoist rope on Liebherr top-slewing cranes is installed by simply pulling it over the tower head and running it through the trolley to the hook. On Liebherr’s top-slewing cranes, the hoist rope pulley at the trolley hook block is simply folded open for easy...

Loading for easy assembly. Liebherr cranes are planned for transport in such a way that subsequent erecting work is simplified. The individual transport units are the complete cruciform base with central ballast, the base tower including ballast, the complete slewing platform with tower head, the complete counter-jib with hoist gear and counter-jib ballast, the complete jib and tower segments. Re-usable frames are available for container transport. Tower segments can then be transported as containers, which cuts the cost. Safety monitoring during climbing. Liebherr’s fast climbing system permits...

Climbing inside buildings. Liebherr top-slewing cranes are ideal for use as climbing cranes in buildings. Liebherr tower cranes can be used in elevator shafts and even in the smallest niches as the project ‘grows’ rapidly. The crane in fact grows with the buildings. Modular design • Many possible combinations of subassemblies within the crane systems • Identical tower design • Customised crane configuration • LiConnect quick jib connection • Quick connection system for jib and counter-jib • Removable crane cab • Pins within easy reach in tower and jib • Quick and simple plug connections on the...
