operation.
• Strong, 60 m long telescopic boom with high telescopable capacities
• Outstanding off road capabilities and manoeuvrability
• “Pick-and-carry“, driving under full load
• Efficient transportation concept, self assembly of the complete crane
• Hydraulic adjustment of the chassis width

Economic transportation and easy assembly
Optimised weights and dimensions
The basic crane with 1 m wide crawler carriers has a weight of app. 91 t without
ballast. Without crawler carriers the unit weighs app. 55 t including the jack-up
cylinders and the traverse beams. It is only 3 m wide and 3.3 m high. By selfcontained disassembly of the traverse beams the weight can be reduced to
app. 48 t (option). Thus the economic transportation is warranted even in countries with restrictive weight regulations.
The crane assembly is carried out optionally by self erection. The basic machine
is transported by low-bed trailer to the job site and then supports itself on the
jack-up cylinders (option). Central ballast, traverse beams, crawler carriers and
superstructure ballast are mounted without auxiliary crane.

High safety
Functional walking surfaces and steps
Large grating areas facilitate safe movement on the crane. During the design of
the walking areas, special attention was paid to easy and fast transportation and
assembly possibilities.
For improvement of accessibility to each crawler, two sets of steps can be attached. Alternatively the variably attachable steps also can be hooked directly to
the chassis.

Great operational diversity
High flexibility
Due to its extraordinary cross-country mobility and the possibility to drive sensitively 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 infrastructural 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
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.

Intelligent crane control
For functional and safe crane operation:
the LICCON computer system
The soft and hardware of the mobile crane control is developed by Liebherr
inhouse. The centre is the LICCON computer system (Liebherr Computed
Control).
• Integrated LML load moment limiter
• Key components are in-house manufactured by Liebherr
• Guaranteed spare parts availability
• Worldwide proven under the most different climate conditions
• Operator friendly
The second control generation LICCON2 is the result of a continuous development by the Liebherr specialists and enables the adaption to the constantly increasing demands of the markets due to its modern and future oriented control.
The data bus technology
Liebherr mobile cranes are completely interlaced by the data bus system. All
important electric and electronic components are equipped with own micro
processors and communicate with each other by only limited data cables. For
the special demands of the mobile crane Liebherr has developed own data bus
systems (LSB – Liebherr-System-Bus). The data bus technology improves the
reliability, the comfort and the safety for road driving and crane operation:
• Higher reliability due to remarkable lesser electric cables and contacts
• Continuous self testing of the “intelligent sensors“
• Comprehensive diagnosis possibilities, fast fault finding
The LICCON working range
limiting system
• Makes the crane operator’s job easier by
automatically monitoring workspace
restrictions such as bridges, roofs, etc.
• Simple programming
• Four different limitation functions:
- Pulley-head height limitation
- Radius limitation
- Slewing angle limitation
- Edge limitation
The LICCON work planner
• Computer programme for planning,
simulating and documenting crane
operations on a PC
• Representation of all the crane’s load
charts
• Automatic search for suitable crane
based on load, radius and lifting height
parameters
• Simulation of crane operations with
outline functions and supporting force
display

Intelligent crane control
LICCON2 – safe and comfortable
With the mobile control and display unit BTT Bluetooth Terminal erection operations, like the actuation of the jack-up
cylinders and the track adjustment can be performed comfortably and safely with intervisibility.
Easily and cost effectively the crane can be upgraded to complete remote control: apart from the appropriate software
on the crane only a panel with two joysticks is needed, into which the provided BTT is plugged in. With the remote control
on the LTR 1220, as well as the complete operation of all the crane movements, the crawler chassis travel can also be
controlled. The unrestricted view of the crane and the load means that safety and convenience of operation can now be
improved even further.
