LIEBHERR ELR 1100 CRAWLER CRANE
optimises customer benefit
T
he new LR 1100 will be available
worldwide from summer 2016. Trans-
port, set-up, lifting capacities and us-
er-friendliness focuses on optimising cus-
tomer benefit.
The newly designed steel fabrication of this
Liebherr crawler crane resembles a tubular
structure and so has not only a high rec-
ognition factor but also allows for optimum
force transmission over short distances.
This results in excellent lifting capacities
even compared to the predecessor model in
this class. These can be further enhanced
by approx. 20% using a swinging counter-
weight, which is available as an option. The
counterweight is swung backwards hydrau-
lically and so produces a higher stability
with increased lifting capacities.
The LR 1100 is fitted with a powerful
230-kW diesel engine complying with
the exhaust emission standards stage IV
/ Tier 4f. For countries with other regula-
tions it is possible to quickly provide en-
gines without exhaust after-treatment.
The new Liebherr crawler crane, type LR
1100, is extremely easy to transport and,
moreover, excels in extremely quick set-up.
The catwalks next to cabin and service ar-
eas are simply folded down for transporta-
tion instead of being laboriously dismount-
ed. Boom foot and crawlers also remain on
the crane during transportation.
Another innovation is the patented boom
foot manipulator making it easy for haulage
contractors to move the crane. Starting at
the boom foot a rope is guided to a short
auxiliary A-frame. Another rope leads from
the A-frame to the counterweight cylinder.
When this cylinder is extended, the coun-
terweight leaves its stationary position and
moves upwards. Thus, there is no need for
the big A-frame to be erected which is a
decisive advantage when entering low ship
holds during shipping or when crossing
under bridges on jobsites. In order to get
the crawler crane ready for operation it is
sufficient to mount the boom. Thanks to the
quick and easy set-up process the LR 1100
is ideal for flexible jobsite applications.
The position of the operator’s cab at a
height of 2.3 m provides the operator with
an excellent overview of the complete job-
site. Moreover, orthopaedic op-
erator seats as well as a modern
climate control system contribute
to increased comfort. A new oper-
ating concept facilitates intuitive
and ergonomic work – in the cabin
the operator can adapt the work-
ing position of the seat, the air
conditioning as well as lighting to
his individual needs.
The new design of the LR 1100
facilitates service work. Com-
pared to the predecessor model
GRP doors on the uppercarriage
are no longer required. This facil-
itates optimum access for service
personnel both from the ground
and from the roof of the basic ma-
chine. Access is comfortable and
safe thanks to the catwalks with
optional handrails and a ladder.
The Liebherr crawler crane, type
LR 1100, is equipped with the
Litronic
®
control system of the
latest generation, which is based
on CANBUS technology. The load
moment limitation included in the
system automatically calculates
the lifting capacities during op-
eration and guarantees optimum
use of the machine. The Litronic
®
control concept is currently the
only one on the market to manage
without storage of load charts or
interpolation of interim values.
Two new assistance systems,
developed in-house, significant-
ly contribute to higher comfort in
the operation of the crawler crane
and improve safety on the jobsite.
The “Vertical Line Finder” ensures
that the load on the rope is hoisted
with perfect verticality. This pre-
vents diagonal pull caused by the
long distance between crane
operator and load. Furthermore, this pre-
vents asymmetric centres of gravity. The
load does not start to sway which causes
less wear to the boom and increases safety
for the jobsite personnel. The second assis-
tance system refers to the “Horizontal Load
Path”. Thanks to this system loads can be
moved to the projected position more pre-
cisely and efficiently following a horizontal
line. This is a decisive advantage especially
in blind spots.
Similar to other crawler crane types of the
LR series up to 300 tonnes the LR 1100
also has a flexible and extendable boom
system. Thus, the new crane is again avail-
able with a fixed jib and a luffing jib.
