5.1.2 DC Electric System
The main hardware for this system consists of the following:
(1) 28VAC 3 phase electric 8kW motor
(2) Motor controller
(3) 250 bar (3626 psi) 8cc variable displacement pump.
Battery Management
Battery condition is permanently monitored by the control circuit, such that when available power has
decreased to 20% of full charge, the battery status circuit begins to restrict the power to the hydraulic
motors. This function causes the drive system to stop & start alternately, signalling to the operator that
re-charging is necessary. At the same time the sounder will begin to sound intermittently and the low
battery warning light will illuminate, reinforcing the charge warning. At this point, sufficient power remains
to drive to the nearest power point. Immediate charging will then be required.
Battery Isolation
The battery-disconnect handle (Anderson) is located inside the chassis, underneath the central access
cover. To isolate the machine control and power circuits from the batteries, pull the release handle. See
section 1.5.4.
Operation
The electric motor is set to run at 2200RPM during booms operation. Booms have full functionality in
electric only mode with no limitations with regard to speed or load.
Batteries
350 AH DYNO Batteries are fitted as standard. The Niftylift charger is tuned to provide the best
performance with DYNO batteries. If alternative batteries are used the charger must be reconfigured to suit
the replacement batteries. Contact Niftylift for further information.
