ProtectIng the envIronment
and lowerIng costs
The engine pump groups from PALFINGER allow emissionfree,
noise-reducing crane operation in particularly sensitive
environments or in indoor rooms. The rapid change of drive
from the truck engine to current mode of the hydraulic
power source also reduces the operating costs.
sustainability does not necessarily have to mean higher operating costs.
Presented as a global première at bauma 2013, the new PALFINGER hybrid
drives successfully prove that protecting resources and environmental-friendliness
can also prove highly profitable from a cost perspective.
At the core of the PALFINGER hybrid technology can be found the electrically
operated engine pump groups. If necessary, they can take on the
electrohydraulic drive work of the PALFINGER crane. The compact systems
are connected to a standard 400 Volt current connection at the place of
use, and immediately start powering the crane hydraulics with up to 365
bar operating pressure. To switch from vehicle engine drive to current
mode, it is sufficient to simply switch over on the control cabinet that has
been assembled. This turns the PALFINGER crane into a low-noise and
emission-free crane in a matter of seconds, one that can work efficiently in
environmentally or noise-sensitive places of use.

Electrohydraulic operation reduces exhaust gas emissions to zero. This
means that the PALFINGER hybrid crane also works in closed rooms such
as halls, tunnel chutes or industrial facilities without exposing the environment
to exhaust gases. Minimisation of drive noise by means of the
electric-motor-driven hydraulic pumps allows people to work continuously
even in areas where noise pollution would be unacceptable. The hybrid
drives are designed as a complete system. This means the crane builder
can attach them quickly and inexpensively to the carrier vehicle without
having to make deep interventions into the on-board hydraulic system.
Depending on the drive power required, two engine variants with 7.5 kW
and 15 kW continuous power are available. An integrated power control
system of the engines covers the high pressure requirement effectively at
high working speed. The energy meter, which is installed in the control
cabinet, allows the power costs to be invoiced depending on the job.
The cost balance with the electric drive is particularly favourable. Compared
to the hydraulic pump drive with a diesel engine, the electric pump drive
minimises the operating costs by up to 80 percent. The PALFINGER hybrid
drive thus pays for itself after just 2.5 years with an average operating
duration.
