Liebherr Piling Rigs of the LRH Series
Liebherr-Werk Nenzing GmbH offers a wide range of carrier machines
equipped with fi xed and swinging leaders for special pile driving applications
requiring large radii and large inclinations to install heavy piles.
Flexibility and
Effi ciency
1
Depending on the requirements basic machines
of the crawler crane series, either duty cycle (HS) or lift
version (LR), or of the drilling rig series (LB) are used.
Combined with solid leaders this high-performance
construction machinery convinces with its high level of
effi ciency and fl exibility.
Liebherr Piling Rig
LRH 100
The LRH 100 is designed as piling rig and is
2
based on the proven LB 20 carrier machine of the Liebherr
drilling rig series (LB series).
Powerful Equipment
Due to the high engine power of the Liebherr
carrier machines with up to 670 kW, hydraulic
3
hammers and vibrators can be driven by
the on-board hydraulics. No additional power pack
is required which signifi cantly reduces the costs for
operation and maintenance.

Litronic® Control System
The core of the Liebherr LRH series is the
Litronic control system. Developed and
4
manufactured by Liebherr, this comprehensive
system encompasses all control and monitoring
functions and is designed for extreme environmental
conditions in tough assignments.
Electronic Evaluation
A modem for remote diagnosis as well as a
process data recording system for recording
5
the work carried out and a process data report
software for evaluating the recorded data are available
as cartridge.
Reliable Service
Thanks to low maintenance requirements, the
possibility of remote diagnosis, quick assistance
6
on site and an effi cient spare parts supply,
Liebherr guarantees the permanent availability of its
products. For qualifi ed service of the machines as well
as comprehensive training of operating and maintenance
personnel, state-of-the-art repair and training centres are
available at the works in Nenzing and at other locations.

Flexibility and Effi ciency
The Liebherr piling rig series with fi xed and swinging leader includes
4 types featuring lifting capacities between 15 t and 80 t.
1
When applied with fi xed leader the LRH units achieve radii of up to 10 m and
inclinations of up to 1:3, depending on the type of equipment. When working
with swinging leader LRS inclinations of up to 1.3:1 are possible.

Liebherr Piling Rig LRH 100
Thanks to the special leader kinematics of the LRH 100 very large radii of up to 8.75 m and inclinations
2
of up to 18° in all directions are achieved. Thus, a complete pile group can be installed from one location
without repositioning the carrier machine.
The rig can be transported in one piece with the hammer mounted and is consequently ready for operation on the
jobsite in a much shorter period of time. With a transport length of 16.5 m and a height of 3.4 m, the unit's transport
weight is only 66 t. The compact design of the basic machine with merely 3 m transport width allows for quick and
cost-effective transportation.
The fl exible hammer design of the LRH 100 offers the possibility of mounting drop weights between 2.5 t and 7 t.
This guarantees optimum adaptation to the required pile type, whether it is a timber pile, concrete pile or a heavy
steel pile.

Powerful Equipment
In order to ideally convert the rig's performance
into high productivity, Liebherr-Werk Nenzing
3
GmbH offers a wide range of effi cient
hammers and vibrators for the LRH series. The motto
is: "everything from one source". Thus, carrier machine
and equipment are optimally matched and interfaces
are avoided.

Litronic® Control System
The proven Liebherr Litronic control system optimally supports
applications with leader. All relevant information, e.g. the leader inclination
4
in X and Y direction, the pile driving depth and the operating data of the
hammer or vibrator, is clearly displayed on the high-resolution monitor. The automatic
control system allows for the vertical adjustment of the leader at the push of a button
and for radius adjustment without changing the leader inclination.

Electronic Evaluation
Quality assurance through process data recording (PDE)
5
The process data is constantly measured during the working process. External sensors can also be connected
to the system. Measurement data relevant to the working process is displayed on the monitor in the cabin. The
operator can then control all processes and, if necessary, correct them. The data is stored by the system and can
be transferred to a computer using a CompactFlash-Card.
Evaluation and visualisation through process data reporting (PDR)
The Liebherr software for process data reporting allows to further process the data on a PC, where they are directly
stored, sorted and visualised. Thus, customer-specific evaluations can easily and quickly be created.

Reliable Service
Permanent readiness for operation is a major prerequisite for a smooth
and effi cient application on the jobsite. Periods of standstill are
6
enormously expensive and have to be reduced to a minimum. A tight
network of service stations with qualifi ed contacts and well-trained Liebherr
service personnel guarantees quick assistance at any time and any location
throughout the world.
14
Page 15
Moreover, failures can be detected and sometimes directly repaired via GSM/
GPRS service modem and remote diagnosis. Software updates as well as
maintenance work can be carried out with this modem. The periods of standstill
are shortened and the rig is operational for a longer time.
Training centres for excellent qualifi cations
For qualifi ed service of the rigs as well as comprehensive training of operating
and maintenance personnel, state-of-the-art repair and training centres are
available in the parent company itself as well as at other locations.
