High flexibility
Due to its extraordinary cross-country mobility and the possibility to drive sen-
sitively with full load, the LTR 1220 offers an extraordinary operation diversity
for e.g. erection of prefabricated components, on long-term sites in the energy
sector, as an assistant crane for the erection of wind power units or at infra-
structural projects.
Telescopable crawlers
The chassis of the LTR 1220 can be hydraulically telescoped from the chassis
width of 4.5 m to the intermediate width of 5.88 m or the maximum width of
7.25 m. Additionally the LTR 1220 also operates on an asymmetric track. Thus
the full capacity can be utilised when working over the side at which the crawler
is fully extended.
On all chassis widths the LTR 1220 can perform crane operations which are
secured by the LICCON safe load indicator. The telescoping can be carried out
in fully 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
inclination up to 4°. To ensure high capacities also under these conditions the
sheaves at the boom head and the assembly jib are manufactured from steel.
