Jungheinrich Diesel and LPG forklift trucks with
hydrostatic drive provide a high handling efficiency,
particularly in shuttle operations (e.g.
trailer and loading bay operations). The power
of this drive technology is demonstrated to full
advantage: dynamic acceleration, rapid direction
changes and precise driving characteristics.
With 5 drive modes, the performance characteristics
can be adapted to the requirements of
numerous varied applications.
State-of-the-art engines from the automobile
industry facilitate precise operation and optimum
productivity combined with low fuel consumption
by means of their electronic control
systems. All motors are distinguishable by low
exhaust emission and comply with at least
the current EU regulations. A regulated 3-way
catalyser for LPG as well as soot filter systems
for Diesel trucks are optionally available.
The workplace is optimally designed with the
operator in mind. It provides safety, protects the
operator’s health and ensures relaxed and concentrated
operation – the best prerequisite for
high productivity throughout the shift.
