Economical transportation and simple erection
Optimized weights and dimensions
The LTR 1100 can be transported with a weight of approx. 53 tons complete with the crawlers on a low bed trailer within a transport width of 3.5 m. To reduce the weight to below 37 tons the crawlers are detached. This is performed optionally in self assembly mode by means of support cylinders (jack-up system), which are pinned to the crawler centre section. Two standard low bed trailers are suf-ficient for hauling the LTR 1100.
Jack-up cylinders with folding brackets for attaching/detaching of the crawlers (optional), 3 folding positions:

Modern crane cab
The backwards tiltable crane cab offer a comfortable and functional working place. The control elements and displays are arranged according to ergonomet-ric factors. Thus a safe and fatigue-proof working is assured.
Fast and safe erection
The mounting of the additional equipment and the counterweight are designed for speed, safety and comfort. For the safety of the operators pedestals and hand holds are provided.

Great operational diversity
High flexibility
Based on its outstanding off road performance and the possibility to drive sen-sitively under full load the LTR 1100 offers a tremendous operational flexibility for e. g. erection of prefabricated sections, at pipeline construction or as auxil-iary crane for the erection of wind power plants.
Telescopable crawlers
In cramped conditions the crawlers can be retracted hydraulically to a chassis width of 3.5 m. Also on this narrow crawler track the LTR 1100 can conduct craneoperations,whicharesafeguardedbytheLICCONsafeloadindicator.The extending and retracting can be performed in assembled condition.
Crane operation with side inclination
Additional operational possibilities are offered by the load charts programmed as standard for working with main boom and assembly jib on surfaces with an inclinationupto4°.Toensurehighcapacitiesalsoundertheseconditionsthesheaves at the boom head and the assembly jib are manufactured from steel.

With proven components
The drive components for the crane operation are designed for high perform-ance and provide for sensitive and precise handling of the load. They are spe-cially tuned for the crane operation and proved in severe long-term tests.

The data bus technology
Liebherr telescopic cranes completely linked through the data bus system. All important electric and electronic components are equipped with own microproc-essors and communicate over only a few data cables. For the special require-ments of the telescopic cranes Liebherr has developed its own bus systems. The data bus system technology improves the reliability, the comfort and the safety of the drive and crane operation:
•Higherreliabilityduetomuchlesselectriccablesandcontacts
•Continuousselftestingofthe„intelligentsensors“
•Extensivediagnosispossibilities,fastfaultfinding
