Fewer downtimes thanks to the<br />
rapid change diesel engine/generator module<br />
The <strong>VOLK</strong> <strong>Hybrid</strong> <strong>Tow</strong> <strong>Tractors</strong> <strong>HFZ</strong><br />
<strong>20</strong> N – <strong>HFZ</strong> 30 N are serially equipped<br />
with a patented rapid change diesel<br />
engine/generator module, the socalled<br />
<strong>VOLK</strong> POWER PACK ® . Unlike<br />
conventional hybrid tow tractors,<br />
these tow tractors have a diesel engine<br />
that is not permanently installed in<br />
the vehicle but is part of a modular<br />
unit. This unit can be exchanged very<br />
easily in about 5 minutes. Because<br />
the <strong>VOLK</strong> POWER PACK ® also has an<br />
integrated tank, a starter battery<br />
and a starter, it can be operated<br />
Less maintenance required thanks to<br />
three-phase technology and Aquamatic<br />
The <strong>VOLK</strong> <strong>Hybrid</strong> <strong>Tow</strong> <strong>Tractors</strong> <strong>HFZ</strong><br />
<strong>20</strong> N – <strong>HFZ</strong> 30 N are serially<br />
equipped with modern three-phase<br />
asynchronous motors. Unlike<br />
conventional direct current motors,<br />
these motors contain hardly any wear<br />
parts, such as carbon brushes, and<br />
are therefore practically maintenancefree.<br />
To minimize battery maintenance<br />
costs, the <strong>VOLK</strong> <strong>Hybrid</strong> <strong>Tow</strong> <strong>Tractors</strong><br />
<strong>HFZ</strong> <strong>20</strong> N – <strong>HFZ</strong> 30 N are equipped<br />
Shorter downtimes thanks to<br />
practically unlimited range<br />
The <strong>VOLK</strong> <strong>Hybrid</strong> <strong>Tow</strong> <strong>Tractors</strong> <strong>HFZ</strong><br />
<strong>20</strong> N – <strong>HFZ</strong> 30 N are equipped with<br />
a very powerful three-phase generator.<br />
With a power output of <strong>20</strong> KW, this<br />
generator continuously provides more<br />
power than is consumed by the<br />
vehicle’s drive motor and accessories –<br />
autonomously. Therefore all<br />
conventional maintenance jobs on the<br />
diesel engine can be performed<br />
independently from the vehicle. For<br />
this reason the <strong>VOLK</strong> <strong>Hybrid</strong> <strong>Tow</strong><br />
<strong>Tractors</strong> <strong>HFZ</strong> <strong>20</strong> N – <strong>HFZ</strong> 30 N can be<br />
operated even during this work. For<br />
example, one of our customers has a<br />
fleet of 70 <strong>VOLK</strong> <strong>Hybrid</strong> <strong>Tow</strong> <strong>Tractors</strong><br />
for which they have two additional<br />
<strong>VOLK</strong> POWER PACK ® modules. This<br />
way a spare unit is always available<br />
to prevent downtimes due to<br />
maintenance.<br />
with an Aquamatic system. This is a<br />
central water refilling system which<br />
enables quick and easy refilling of all<br />
battery cells to the correct fill level. To<br />
ensure that water refilling is not<br />
forgotten in the hectic pace of daily<br />
business, the vehicles are equipped<br />
with an electronic electrolyte level<br />
indicator which dependably warns the<br />
driver and the service personnel when<br />
the electrolyte level gets critical.<br />
except for temporary load peaks. As a<br />
result, the generously dimensioned<br />
80 V/3<strong>20</strong> Ah traction batteries can be<br />
easily recharged during diesel operation.<br />
External battery charging is<br />
usually not necessary.
