Introduction
Technical description
The power required is supplied by the battery
installed in the truck. Thanks to the twin
pedal system continuously variable control of
forwards movement and reversing is possible
via the digital control system.
Steering
Kickback-free steering of the forklift truck ,
which is sensitive and virtually free of play, is
carried out manually using the small steering
wheel of the hydrostatic steering on the
steering cylinder of the steering axle.
Hydraulic system
The hydraulic system consists of an electric
motor with a hydraulic pump for the steering
and for the lifting and tilt cylinders of the lift
mast, a hydraulic oil tank with a breather and
an oil dipstick as well as a suction and pressure
filter.
Operation
With one accelerator pedal each for forwards
motion and reversing, the drive motors offer
continuously variable control from stationary
to maximum speed in both directions of travel
. The driver always has both hands free for
steering and control of the work movements .
Fast reversing and energy-saving stacking is
the result.
To control the work movements, lifting,
lowering and tilting, there is only one operating
lever (joystick).
Another operating lever (joystick) is fitted to
operate additional attachments.
If wished, all work movements (lifting, lowering
and tilting) are also available as individual
operating levers.
Brakes
The vehicle may be equipped with several
independent braking systems. They may
consist of an electric and hydraulic brake
and a hydraulic parking brake. The standard
4
version is the hydraulic operating brake, which
is activated by pressing the Stop pedal and
controls the multi-disc brake in the drive axle.
The hydraulic parking brake only activates the
multi-disc brake in the drive unit. The electric
brake (regenerative braking) is activated
via the accelerator pedals when the pedal
is operated by the driver in the opposite
direction.
The LBC brake (special equipment) (Linde
Brake Control) is activated via the accelerator
pedals when brought into neutral by the driver.
When the accelerator pedal is released,
electric braking is effected by the Linde Brake
Control (LBC) system. If wished, this can
be switched off via a diagnostic software
program.
DANGER
If LBC braking is disabled, automatic braking does
not take place with release of the accelerator
pedal. If the LBC is switched off, a notice "no motor
braking" must then be attached so it is clearly visible
to the driver.
Please contact your authorised dealer in this re-
gard.
NOTE
This forklift truck is also equipped as standard
with an energy recovery system, which feeds
back into the battery the generator energy
resulting with braking and changes in direction
.
Electrical system
The well-protected electrical system is posi-
tioned at the front on the drive axle. The re-
quired energy is supplied by a 48-volt battery
(24-volt battery with E 12, E 15) installed in the
frame. A hinged side access panel allows the
battery to be changed quickly and easily.
NOTE
It is not permitted to open the control housings
or indicator units during the warranty period;
otherwise all claims to guarantees will expire.
