<strong>ARV2000</strong> - <strong>New</strong> <strong>Hydraulics</strong>
Optimised high-tech system<br />
The Armoured Recovery Vehicle (Leopard 1) has<br />
proved itself on numerous missions. But even with the<br />
best there is room for improvement! The engineers at<br />
<strong>Flensburg</strong>er Fahrzeugbau Gesellschaft (<strong>FFG</strong>) know the<br />
potential, but also the problems, of this tank. After all,<br />
<strong>FFG</strong> is one of the few companies to have been repairing<br />
these vehicles for many years.<br />
<strong>FFG</strong> rated the safety of the crane system and its operation<br />
as no longer up to date and has therefore developed<br />
a new hydraulic concept.This high-tech hydraulic<br />
system offers several advantages at a stroke. It will work<br />
absolutely perfectly and reliably in even the toughest<br />
conditions, so it satisfies stringent military standards in<br />
every particular. <strong>FFG</strong> uses industrial components that<br />
have proved themselves thousands upon thousands of<br />

times. Every single part has been tested in the field. And<br />
the system’s simple operation has been adapted to the<br />
operating structure of the “Buffelo” recovery tank.<br />
In early 2001 <strong>FFG</strong> made the <strong>ARV2000</strong> recovery tank<br />
with the new hydraulic system available to the<br />
Bundeswehr Technical Centre for Engineer and General<br />
Field Equipment (WTD 51) in Koblenz, where it was<br />
thoroughly tested, trialled and evaluated over an<br />
extended period.The vehicle passed all the necessary<br />
tests, including cross-country, EMC, vibration, climate,<br />
cold and endurance, without exception.<br />
Once more the optimised hydraulics of the <strong>ARV2000</strong><br />
recovery tank reflect the innovation and long experience<br />
of <strong>FFG</strong>.

Emergency hydraulics<br />
All components of the existing hydraulic system have<br />
been replaced apart from the hydraulic cylinders.The<br />
vane-cell motors have been replaced with state-of-theart<br />
inclined-axis motors. <strong>New</strong> variable displacement<br />
pumps ensure the necessary pressure. A load-sensing<br />

supplies the hydraulic cylinders with oil.The winch drives<br />
and the swivel drive for the crane arm operate in “closed”<br />
hydraulic circuits.This means that the hydraulic system<br />
can get by with fewer components.This development<br />
also offers the enormous advantage of highly sensitive,<br />
load-independent manoeuvrability.<br />
