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 Features True speed pedal Stand in slope 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 Piston pumps Electric servo 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 Controllability 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 Located behind the cab New battery design (Option) 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 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
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
