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 />
an electric motor as well as a diesel<br />
engine. Therefore they can be used<br />
both in closed spaces and outdoors.<br />
The diesel drive can be switched on or<br />
off without any jerks and without<br />
interrupting traction – regardless of<br />
the speed and driving direction. This is<br />
possible because the driving axle is<br />
always driven by the electric motor.<br />
When the diesel engine is switched on,<br />
a generator driven by this diesel<br />
engine generates the current required<br />
for the electric motor. Excess power<br />
is used to recharge the traction<br />
batteries. After the diesel engine is<br />
shut off, the required current is taken<br />
from the traction batteries.
