Description of truck

Steering (1): Low steering forces of 15 N and an ideal ratio of 5 steering wheel rev-
olutions for a steering angle of 180°. A hydraulic steering motor drives the steering
axle via a gear wheel pair. Efficient energy usage due to the implemented dynamic
load sensing system. The steering column is adjustable.
Driver seat (7): The driver seat is a comfort seat with lengthwise, backrest and weight
adjustability. As safety feature for the driver, the seat is equipped with an automatic
lap belt.
Electrics/electronics: Three-phase technology via CAN bus, reduces the number of
cable harnesses. This results in a lower susceptibility to wire breaks and speeds up
malfunction finding. Energy recuperation by means of regenerative brake. Controller
error analysis and programming occurs via a PC connected to the provided interface.
As an option, five drive programs for different loads and application purposes are
available.
Drive system: The complete drive unit is screwed to the counterweight. The steera-
ble rear wheel is also the drive wheel. It is driven by a stationary, low-noise three-
phase gear motor. The electronic drive controller allows the drive motor speed to be
continuously regulated and thus ensures smooth, jolt-free starting, powerful acceler-
ation and electronically controlled braking with energy regeneration. In case of the
steering angle acquisition (o), the travelling speed is automatically reduced in ac-
cordance with the steering angle.
Brake system: The hydraulically actuated power drum brake on both front wheels
requires only little pedal force to effectively brake the truck. In addition, the truck is
regeneratively braked by the drive motor. Thus, operation of the service brake is
made almost obsolete, and energy consumption and brake wear are minimised.
Overhead guard (8): Constructed as a sturdy four-pole roof. Narrow roof sections
and cross beams ensure good allround view. The overhead guard is prepared for a
roof configuration with front and rear safety glass pane.
Hydraulic system: Two systems: Solo Pilot (t) and Multi Pilot (o).
Solo Pilot: Individual levers for lifting/lowering, forward/backward tilting and, as an op-
tion, two additional levers for auxiliary functions (e.g. side shift, clamp, etc.). The drive
direction switch is integrated in the lifting function lever.
Multi Pilot (option): All hydraulic functions, drive direction switch and horn have been
combined in one lever.
The hydraulic unit speed is always adapted to the demands of the respective function.
Lifting mast (2): The high-strength steel sections are extraordinarily narrow. An ex-
cellent view on the forks is thus ensured.
Lifting rails and fork carriage run on lifetime-lubricated, maintenance-free angular roll-
ers.
