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.
