A
lthough the current global situation
might not give reason for a
celebration, at Maats Pipeline
Equipment in the Netherlands
there is more than one reason to
feel positive in 2009. The company has been
successfully involved in the rental of heavy
construction equipment for over 25 years; and for
15 years it has been the official partner of Liebherr
for the sale of new Liebherr pipeline equipment.
Liebherr recently began the delivery of two
completely newly designed pipelayer models to
the market - the RL44 and the RL64.
Over the past 25 years, the Maats name
has been firmly established as one of the major
rental companies in the pipeline industry. With
its head office in Goor in The Netherlands and
offices in Datteln (Germany), Ankara (Turkey) and
Batam (Indonesia) and a permanent staff of 35
- 40 people, Maats serves customers worldwide.
In addition to its own offices, Maats uses a
network of selected agents, co-operating with
Liebherr dealers and service partners worldwide
to guarantee global coverage for both sales and
service.
Over the years, Maats has increasingly
specialised in pipeline construction equipment.
Although being a relatively small company, Maats’
main priority is to provide a high level of service
and share its vast experience with its customers.
The company is able to carry out consultations
at an early stage, based on the specific customer
or project requirements. With highly experienced
staff and a workshop, Maats is able to supply
customer specific solutions by adjusting
machinery to suit its intended purpose.
Here, some examples of equipment developed
by Maats are discussed.
The welding tractor: Liebherr
SR712BM
This machine was developed on the basis of a
Liebherr crawler tractor. It can be equipped with
a compressor, a generator and up to six welding
power sources; either for conventional or for
automatic welding. The biggest advantage of this
welding tractor is that all equipment is powered
by the hydraulic system of the base machine,
which is the diesel engine. There is no separate
engine or hydraulic system for the compressor
and generator, keeping the number of parts to a
minimum and limiting fuel consumption.
Conveyor belt shifters: Liebherr RL52
and RL64
This customised pipelayer is used in open pit
mines worldwide to shift up to 3.5 km long
conveyor belts that are used for the transport of

(mostly) lignite and overburden. One of the adjustments is the
addition of a potentiometer. With this, the operator can adjust
the driving direction from straight forward to a continuous
sideways drive. Some of these machines are being equipped
with GPS, making it possible to shift the conveyor belt within
5 - 10 cm of a registered location.
Liebherr multi equipment
The Liebherr multi combines a regular pipelayer with a
welding tractor by adding a front and rear platform with
the necessary equipment for welding. This machine can
be used for all types and systems of welding, just like
a normal Liebherr welding tractor. The same machine
can be used for lowering in the pipe afterwards. This
means fewer machines on the project; resulting in less
maintenance, less fuel consumption and even fewer
operators. This option can be supplied for all types of
Liebherr pipelayers.
The sale and rental programme
More generally, the Maats sale and rental programme can be
divided into three main categories:
Pipelaying equipment
Pipelayers: 20 - 90 t
Roller cradles: 4 - 60 in.
Pipe welding equipment
Pipe facing machines: 28 - 60 in.
Internal line-up clamps 6 - 100 in.
External line-up clamps 6 - 56 in. (sale only)
Welding tractors.
Pipe bending equipment
Pipe bending machines 6 - 66 in.
Hydraulic and pneumatic bending mandrels 6 - 56 in.
Additional equipment is also available, such as
compressors that can be used with the above machinery.
Also available are padding machines that can be used in
combination with either pipelayers or dozers.

Full service also means flexibility. As a result, Maats
does not publish a full equipment list. This gives room for
offering alternatives and the possibility to source equipment
elsewhere. Maats has established an equipment pool with
several companies that own pipeline construction equipment,
making sourcing and finding alternatives even easier.
Most recently added to the equipment pool are two new
Liebherr pipelayer models from the 4th
Generation - the RL44
and RL64. To complete the programme of Liebherr pipeline
equipment, in 2009, Maats will also introduce the replacement
machines for the pipelayer RL22B with a lifting capacity of
20 t and for the welding tractor SR712BM.
Two new Generation 4 pipelayers
Based on the successful product ranges of the new
Generation 4 dozers and crawler loaders, Liebherr has
recently introduced two new pipelayers. The launch of these
include the new RL44, with a 48 t lifting capacity; driven
by a Liebherr Diesel engine with 175 kW/238 HP and an
operating weight of 35 100 kg. The new RL64 pipelayer has
a 91 t lifting capacity, with an engine output of
275 kW/367 HP and an operating weight of 58 000 kg at the
top end of the line.
Strictly following customer demands and the experience
of over 35 years in manufacturing hydrostatic driven dozers
and crawler loaders, Liebherr pipelayers have set industry
standards over the years. Asymmetric track width for best
load distribution, hydrostatic travel drive and the joystick
control concept for maximum operating safety and easy and
precise operation are only a few examples.
Liebherr’s pipelayer, in the compact class with a fully
automatic folding boom for easy transportation, has
been awarded with the British Petrol Innovation Price for
groundbreaking new technology in the pipeline industry.
Both new Generation 4 pipelayers - the RL44 and the
RL64, have been designed with a focus on both buyer and
operator requirements. Customers in the pipeline industry can
now benefit from the added value of the new machine; with
the highest performance, best economy and reliability as well
as excellent operator comfort and safety. Further advantages
of the new machines are discussed below.
Performance
The new machines feature a revolutionary drive concept
from Liebherr, with uninterrupted power on both tracks,
wear-free service brakes and an
unmatched manoeuverability including
turning on the spot. The stepless
speed control eliminates the need
of gear shifting, providing easiest
operation with just one travel joystick.
This results in the highest drawbar
pull over the full speed range - not
only important for best performance
on the job site but also for working
safety. A hydraulic hoist winch with
infinite and precise speed control,
including an automatic multi disc
brake, is also standard on all Liebherr
pipelayers.
Economy
The robust Liebherr diesel engines
operate at a constant low and very
economical speed of 1800 rpm. This
reduces fuel consumption, is important
for a long component life of the engine
and – together with the on demand
hydraulic cooling system – keeps the
noise level at a minimum. Centralised
service points with easy access,

including a 40° tiltable cab, long service intervals and a
service friendly layout help keeping service and operating
costs down.
Reliability
Well-proven technologies and high product quality are what
keeps machines ready for use. Liebherr develops and builds
its own components and assemblies specifically for use on
construction and pipeline machinery. As a result, their strength
can be assured however arduous the task. Liebherr’s range
of pipelayers feature hydrostatically driven fans and wide
mesh radiators to ensure optimum cooling performance, even
in very hot and dusty environments. With well dimensioned
and long-term tested components and a range of deep
temperature kits, Liebherr’s range of pipeline equipment
withstands the roughest ambient conditions - from the desert
to the arctic winter.
Comfort
Another highlight of the new Generation 4 pipelayers is the
brand new cab, with generous dimensions and a strong air
conditioner. The new cab design provides the best possible
visibility on the load and the hook, and an outstanding
view to all sides. The well-planned cab layout makes
conditions ideal for a stress-free and efficient operation of
the machine. All instruments and controls are clearly laid out
and easy to reach. The operator’s seat, with a wide range of
adjustments, is turned 15° to the left for the optimum view.
Safety
All Liebherr pipelayers feature one separate joystick for all
travel and steering functions, and another for the control of
the boom and hook - making the operation of the machine
easy and precise. An integrated ROPS protection is standard
on all machines. Together with the standard free fall device
and a hydraulically stabilised boom, the machines provide
maximum safety for the operator.
