2.1 Truck

Safety devices: An enclosed truck contour with rounded edges ensures safe hand-

ling of the truck. The overhead guard protects the driver from falling objects.

The Emergency Disconnect switch immediately cuts out all truck movements in ha-

zardous situations. Safety gates on either side of the cab interrupt all truck move-

ments as soon as they are opened.

Travelling and lifting/lowering can only be activated when the foot switch is pressed.

Drive: 4.4 kW (S2 60 min) vertically mounted, heavy duty threephase motor

(asynchronous). The motor is directly attached to the single-wheel driving gear,

ensuring rapid and trouble-free maintenance.

Brake system:

– The truck can be braked gently and without inducing wear by pushing back the

travel selection switch or steering in the opposite direction. This feeds energy into

the battery (operating brake).

– The electromagnetic spring pressure brake acting on the drive motor serves as a

parking and handbrake.

Steering:

Especially smooth steering with threephase drive system. The practical steering

wheel is integrated within the control panel. With the mechanical rail guidance system

the drive wheel is set to the straight-ahead position at the press of a button.The

position of the steered drive wheel is shown in the display unit. The steering angle is

+/- 90°, offering maximum manoeuvrability in narrow main aisles.

In wire guidance systems, steering is automatically managed by the truck controller,

manual steering is not available.

Controls and display units: The functions are activated via ergonomic thumb mo-

vements to ensure fatigue-free operation without straining the wrists; sensitive appli-

cation of travel and hydraulic movements to spare and position the goods exactly.

The display unit is used to display all the important driver information such as steering

wheel position, overall lift, truck status reports (e. g. faults), service hours, battery ca-

pacity, time and wire guidance status etc..

Hydraulic system:

All hydraulic movements are controlled by a maintenance-free 9.5 kW threephase

motor with a flanged low emission gear pump. Oil is distributed via magnetic switch

valves. The varying oil requirements are controlled by the speed of the motor. When

the truck performs a lowering operation, the hydraulic pump drives the motor which

then acts as a generator (regenerative lowering). The energy produced is then fed

back to the battery.
