WD 13 15 Frame The robust stabile frame

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. 01. 12. 2001

WD 13 / 15 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 13 11. 6 x 5. 7” WD 15 15. 0 x 6. 0” or 15. 0 x 7. 6” depending on frame size Material: Tractotan Drive Wheel: WD 13 / 15 15. 7 x 6. 3” Material: Polyurethane 01. 12. 2001

WD 13 / 15 Drive system: • Stationary high performance ~ ac drive motor with 7 k. W (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: • 01. 12. 2001 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 +/- 90 o 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 don’t 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. 01. 12. 2001

Design Mast • 01. 12. 2001 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.

Ergonomic Design Operators Compartment • • • 01. 12. 2001 The drivers seat, control panel and foot pedals rotate 30 o in the load direction and 10 o 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

Ergonomic Design Height Selector 01. 12. 2001 • 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.

Ergonomic Design Operator Console 01. 12. 2001 • 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 …

WD 13 / 15 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 Estop 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. 01. 12. 2001

WD 13 / 15 Hydraulic • All hydraulic movement is provided by the ~ ac 21 k. W 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. 01. 12. 2001
