Introduction 3
Travel drive
The drive is delivered through a 3-phase alternating current electric motor
(hydraulic motor). The speed of the hydraulic motor is transferred via the
single stage transfer gearbox and the cardan shaft to
the front and rear axle.
The machine has two speed ranges: Turtle and Hare. After selecting the
travel direction, as soon as the accelerator pedal is pressed, the machine
will start moving. Travel speed depends on the speed of rotation of the
electric motor. The infinitely variable adjustment control is performed
within the selected speed range via the accelerator pedal.
A change in the travel direction is possible at any time, even while
moving. If the accelerator pedal is being pressed when changing the travel
direction, the machine brakes and then accelerates immediately
thereafter in the new direction.
If the machine is braked by easing off the accelerator pedal or stepping
on the brake, or if the machine is rolling downhill without pressing on the
accelerator pedal, then electricity is fed back into the battery.
Indicator lights on the instrument panel illuminate in case the fixed
temperature is exceeded in the hydraulic motor.
In order to reach maximum speed, the axles and the gearbox must
be run for at least 10 operating hours and the lube oil in the axles must
have reached a temperature of approx. 50°C (122°F)!
Furthermore, maximum speed is only reached on level, asphalted ground,
and when the attachment is empty!
