Technical presentation ECF50-90

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

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

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

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

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!

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

Kalmar Control System, KCS

CAN-bus

• 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

Summary
