Truck

Steering (8): When a load is applied to the driver seat the steering is switched to
Standby. The steering unit runs at a preset idle speed. Depending on the steering
request the steering pump is increased and the travel speed is reduced depending on
the steering arc (“"CurveControl”"). The steering angle is indicated in the display.
Driver seat (2): The driver seat is a comfort seat and the steering column is
adjustable. There are storage places for documents or personal belongings of the
driver. The MULTI-PILOT combines all hydraulic functions and the travel direction
switch in one single lever. The overhead guard (1) is prepared for a cabin installation
and thus can be easily retrofitted.
Electric/electronic system: Sophisticated three-phase AC technology enables data
transfers with few cables only (CAN bus). Thus we achieve decreased susceptibility
to faults caused be broken cables as well as considerably faster fault isolation. The
complex TC system (Total Control) is designed for simply, safe, and flexible usage.
Depending on the load the driver can select from different operating programmes:
from high-performance to energy-saving. Convenient and very fast fault analysis and
programming can be performed via PC.
Drive and brake system: The front drive offers ideal traction to the drive wheels at
all times.
The hydraulically actuated oil-bath multi-disk brake used a service brake is practically
maintenance-free. The encapsulation in the transmission allows applications even in
aggressive environments. In addition, the lift truck is generatively braked via the travel
motor. Thus the energy consumption is minimised.
After approximately 15 sec standstill of the truck or 1 to 15 sec (adjustable) after the
driver seat is relieved the spring-loaded brake engages.
When actuating the accelerator the spring-loaded brake is automatically disengaged.
Hydraulic system: All functions must be executed sensitively, proportionally, and
simultaneously (only if this does not impair the safety). For higher efficiency a
hydraulic unit and a steering booster motor function separately from each other. The
micro pressure filter can be changed from the top (without spilling hydraulic oil).
Lifting mast (7): Our goal is optimising the view. The high-strength steel profiles are
narrow, which is especially notable in the three-stage lifting mast with its good view
to the fork arms. The same good results are achieved for the fork arm carriage.
The lifting mast as well as the fork arm carriage move on prelubricated and thus
maintenance-free cocked support rollers.
