3-WHEEL ELECTRIC LIFT TRUCKS

Taking the industry lead...

The PRO 5 series will do just that and more with:

• Operator compartment design that optimizes driver comfort to keep your operator fresh, effective and productive...all day, everyday.
• AC Drive & Hydraulic motors promote energy efficiency that generates more run time per battery charge for greater productivity and increased efficiency.
• Elimination of motor brushes, communicators and directional and hydraulic contactors decreases maintenance and minimizes downtime, to reduce overall operating costs.

from front to back...the new PRO 5 Series will satisfy the most demanding owners and operators.

OWNERS...want a lift truck that makes good economic sense

OPERATORS...want a lift truck that is both comfortable and productive

ALL OF THEIR NEEDS ARE MET BY THE PRO5 SERIES!

• Rear View Mirrors- keep operators posted, aware, and alert to what's going on around them.
• Lockable Parking Brake Lever with Warning- double-acting lever actuation with button release keeps truck braked while exiting and entering vehicle. Buzzer activates when operator leaves seat without engaging park brake.
• Directional Lever- hand actuated to easily select forward or reverse for smooth and responsive directional change.
• Seat Belt Indicator- activates as a warning if seat belt is not fastened when truck is in operating mode.
• Fully Hydraulic Power Steering- has no mechanical connection between steering wheel and steer axle which eliminates kickback and gives operator precise steering control with low steering effort regardless of truck speed.
• Roomy Operator compartment- designed for comfort. Optimized pedal positions, combined with an infinitely tiltable steering wheel and fill slide seat adjustment effectively eliminates operator fatigue.
• Outstanding Visibility- achieved with SEE-THRU mast and overhead guard with a low rise cowl design that optimizes operator sight lines forward, up and to the load.
• Breakthrough Anisometric overhead Guard-Revolutionary design permits quick and easy installation of weather panels when and where they are needed.
• Audible Back-up Buzzer- is standard equipment to alert pedestrian traffic of vehicle proximity and location.
• Tool-less Battery Side Covers- enhanced stylish appearance and permits convenient and open service access.

Productivity...is standard equipment!

The ultimate judge of any Lift Truck is its productivity and that's where Doosan's AC CONTROL SYSTEM really shines!

AGGRESSIVE ACCELERATION + PRECISE CONTROL + RUN TIME PER BATERY CHARGE = PRODUCTIVITY

With just the touch of a button, operators can select the performance mode that best meets their production needs.

• E-Mode (Economy) maximizes energy savings for over 8-hours operation on a battery charge.
• S-Mode (Standard) Performance equivalent to DC motor powered vehicles.
• H-Mode (High Speed) Maximum drive & lift speeds.

And thanks to our closed-loop speed feedback systems, the ITC (Intelligent Torque Control)continuously monitors loads on the traction and hydraulic motors to maintain equivalent operating speeds whether truck is loaded or unloaded. This allows the operator to optimize operational efficiencies thereby maximizing the productivity equation.

AC MOTORS

control Drive Hydraulic and Steering functions. Utilizes 3 inverters to convert current in the truck battery to smooth, precise and productive operation. Hydraulic motor and twin drive motors are brush less making them virtually maintenance free.

The combination of LED displays and 7-digit graphic LCD display intelligently provides operators with all the information they need, including operational information, diagnostics, and programmable settings. the 4 display buttons offer a choice of four power modes: heavy duty, standard duty, economic duty and slow travel speed mode. Standard instrument images are displayed at the right.

AC CONTROLLER

The Command Center of the PRO5 series is the AC Controller consisting of a main logic board and three independent power modules with direct links to each drive motor and the hydraulic motor. This control unit regulates and monitors the following function:

• Anti-roll Back and anti-roll down with adjustable ramp stop time
• Regenerative braking
• Electrically Assisted Braking
• Static return to off (SRO)
• Drive speed compensation (Load/Unload)
• Drive speed acceleration/deceleration/reduction
• Continuous lift speed control/Pump motor speed compensation
• Battery discharge indicator with adjustable reset value
• Over temperature protection for power modules and motors
• Low and high voltage limit
• Diagnostics and stored error codes
• Power line fault detection (Fuse/Contactor)
• Continuous temperature measuring (controller, motor)
• Full protection against short or open circuits
