  1. Technical presentation ECF50-90

  2. Why ECF? • Create a top of the line electric FLT • Improve efficiency • Reduce maintenance • What is retained? • Cab • Lifting equipment • Overall chassis design • What is new? • Traction • Hydraulics • Power electronics • AC technology • Battery • Kalmar Control System

  3. Traction • Dual drive system • Wheel motors • Electronic differential • Individual motor speed control • Designed for heavy duty applications • Features • True speed pedal • Stand in slope • Regeneration of kinetic energy to battery • Electric brake force adjustable by driver

  4. Hydraulics • Dual pump system • Two pump motors • Controllability • Optimized flow control • Reduced energy consumption • Piston pumps • Parker F1, 25,6 cm3/rev. • Max. pressure @ 0 rpm • Optimal placement • Electric servo • Filter placement gives excellent service access • One main valve gathering all hydraulic functions

  5. Power electronics • Efficient thermal dissipation • IMS technology • 70 mm finned heat sink • Electronically commutated fan • Fresh air inlet • Controllability • 2 wire CAN-Open bus from KCS • No mechanical components for direction • selection or regeneration • Rapid response and smooth transitions • Features • Electronic differential • Stand in slope intelligence • Regeneration of kinetic energy to battery • Electric brake force adjustable from KCS display

  6. AC Technology • Efficient motors • Good torque @ high rpm • No carbon brushes or commutators • No contactors • Helps to provide a longer working cycle for each battery • AC technology is the future!

  7. Battery • Capacity • 80 V • Up to 1600 Ah • Charger size up to 300 A • Located behind the cab • Operator not sitting next to the power supply • Allows for great freedom of choice • Easy access • New battery design (Option) • Improved visibility • Fixed, pulled out or lifted with fork pockets • Complete solutions for battery exchange system

  8. Kalmar Control System, KCS • Well proven electronic control system • CAN-bus technology • Efficient diagnostics • Display in steering wheel panel • Remaining battery capacity • Battery voltage • Machine hours • Time to service • Adjust electric brake level in display • Drive train diagnostics • Kalmar Smart Link compatible • Standard in ECF model CAN-bus

  9. Summary • Cab, lifting equipment and overall chassis design retained • New traction system, dual drive • New hydraulic system, dual pump • All AC technology • Designed battery available • KCS in all ECF models
