WD 13 / 15 Frame The robust stabile frame is
based on a skeletal design. This enables
technicians unhindered access to the vehicles
operational components and the battery. All
covers are designed to be removed or open on
hinges. The vehicle chassis width, is measured
over the load wheels. The frame width is adapted
to the customers specific load and warehouse
requirements. Chassis widths are available in
sizes ranging from 47.6 to 67 in roughly 2
increments.

Benefits of Man Down vs. Man-Up

• Increase productivity up to 25 with the use of
  the built in height selector horizontal
  positioning (option)
• Save up to 25 of energy consumption without
  raising the operator cab
• Maneuverable and able to negotiate smaller
  intersecting aisles due to the elimination of the
  cab dimension
• Fast operator adaptation to controls similar to
  standard conventional counterbalance forklift.
• Operator comfort enhanced - elimination of
  constant up-down (elevator movement) and in the
  sommer even possible fatigue under hot roofs

Wheels The load wheels are mounted on
independent load axles. The bearings are conical
roller bearings that provide ease of maintenance
and adjustments as well as very easy tire
exchange when required. Load Wheels WD

• Drive system
• Stationary high performance ac drive motor with
  7 kW (KB 60 min.) bolted directly on to the
  single wheel transmission. The ac motor
  requires no maintenance (NO brushes) and has a
  very high torque rating.
• Steering
• An exceptionally smooth and responsive electrical
  steering system. The small operator steering
  wheel is incorporated into the pilot control
  center. When operating in rail guided mode, a
  push button sets the steered wheel to the
  straight position disabling the steering wheel
  input. The position of the steered wheel is
  indicated in the operators LCD display. The
  steering response ranges between /- 90o making
  this 3 wheel vehicle exceptionally maneuverable
  in tight intersecting aisles.

• Load Handling Attachment
• The standard vehicle is outfitted with a turret
  attachment. Loads can be placed or retrieved from
  floor locations. Loads directly in front / left
  or right side of the vehicle can be handled by
  this attachment in a narrow aisle configuration.
• All end positions of the attachment (side shift
  or rotation) are automatically end dampened.
  Operators dont have to worry about feathering
  the load - the equipment is programmed to do this
  task automatically.
• For quick rotation of the load, the shift and
  rotation movement can be synchronized and
  coordinated for the specific load aisle size.
  This option allows the operator to rotate the
  load in the narrow aisle with the touch of a
  button.
• Optional telescopic load attachments are
  available to handle skid type or pallets without
  bottom boards further reducing the normal
  working aisle (load 8) over the standard
  turret attachment (load 16).
• The turret attachment may also be fitted with
  synchronous or asynchronous fork positioner.

11
Design

• Mast
• The mast selection covers 2-stage clear view or
  3-stage full free lift models. Both are precision
  manufactured with double T profiles, cross braced
  with channels, the design provides torsion
  resistance and bend stability. These features are
  desirable to narrow aisle equipment in that in
  minimizes mast sway or lean during the load /
  unload cycle. The hydraulic cylinders are mounted
  on the outside of the mast profile enhancing the
  operators view.

12
Ergonomic Design

• Operators Compartment
• The drivers seat, control panel and foot pedals
  rotate 30o in the load direction and 10o in the
  steer wheel direction - under operator control
  via toggle switch in a stepless manner.
• The comfort seat is suspended and dampened
  against vibration. The seat is adjustable to the
  operators body weight and dimensions. The control
  panel and integrated arm rest are height and
  distance adaptable.
• All functions for lift, lower, side shift and
  rotation are enabled via thumb

13
Ergonomic Design

• Height Selector
• The integrated height selector mounted in the
  control panel of the pilots compartment allows
  the operator to select the load level via
  keyboard entry. When reaching the desired level
  the lift or lowering process is completed. The
  load / unload process is also controlled by the
  height selector pending operator initiation at
  the desired horizontal position.
• The height selector is setup to control multiple
  zones with varying rack levels. The integrated
  system infinitely controls lift / lower velocity
  based on a programmable ramp slope to user
  defined end fork position, maximizing operator
  productivity.

14
Ergonomic Design

• Operator Console
• The spacious physiologically designed work
  environment includes comfort seat and optimized
  positions for all the control elements. The
  results furnish the operator with a sense of
  unparalleled handling control which further
  reduce operator fatigue and stress over long
  periods of operation.
• Control. Operational conditions are displayed on
  the LCD such as Lift Height, Battery Discharge
  Indication, Time, Position of Steer Wheel, etc

Height Selector and horizontal positioning aids

• Integrated Height Selector with automatic load /
  unload cycle
• Horizontal positioning with aid of laser pointer
  located on mast and pointing to floor or rack
  markers.
• Help the operator position fork accurately and

ac, Energy Control and CAN - Bus
Safety

• CAN-BUS
• CAN-Bus and continuous measurement sensors make
  end switches and adjustments obsolete. 60 less
  cable and wiring over conventional vehicles.
  Control of all sensors based on priority protocol
  maximizes operational safety. Automatic dampening
  set on all hydraulic end movements, as well as
  the mast transition between stages. The
  technology is also commonly found in the
  automotive heavy equipment industry in harsh
  environmental settings.

Brakes a) The vehicle can be brought to a halt by
releasing the accelerator or by changing the
travel direction turning the drive motor into a
motor brake generator. This normal method of
braking does NOT use the vehicle brakes providing
wear free braking. b) More remotely the vehicle
can be stopped via hydraulically activated
expanding shoe brakes located in the load wheels.
A standard brake pedal is provided for the
operator. The maximum brake retardation is
automatically dynamically set, depending on the
lift height of the forks (or load) while
traveling inside or outside of the working aisle.
This eliminates to a high degree any operator
error during the braking process, maintaining the
maximum stability for the vehicle. c) The
electromagnetic motor disc brake acts as a
holding brake during the load / unload process
and also as a parking brake when the vehicle is
turned off. This brake is also applied during an
E-stop condition. d) All wire guided vehicles
are also provided with a solenoid activated
hydraulic brake system. The release during an
E-stop condition acts on the front load wheel
brake shoes. The brake pressure is regulated
depending on the lift height of the forks (or
load) while traveling in the working aisle.

WD 13 / 15

• Hydraulic
• All hydraulic movement is provided by the ac 21
  kW pump motor coupled to a very quiet gear tooth
  pump. The hydraulic oil distribution is
  controlled via micro magnetic valve blocks. The
  volume of oil is a function of the control system
  that controls the rpm of the motor rather then
  bypass fluid via a spool or proportional valve.
  Only the amount of oil required to operate the
  function is provided. While lowering the pump
  motor is turned into a generator. The energy
  created is returned to the battery.
