Boom System

The boom system uses a maximum of 25L/min from the pump. Functions can be operated proportionally

and simultaneously until the demand reaches 25L/min. If the demand exceeds 25L/min then the flow is

shared between the functions with priority given to the function with the lowest operating pressure.

DC Only Mode

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.

Hybrid Mode

In Hybrid mode the engine is set to run at 1800 RPM in a no load condition. The engine can be loaded

either by battery charging or by operating the booms. If the revs drops below 1700 RPM, battery charging

stops temporarily and the engine then supplies full power to lift the booms, if it drops further then the

electric motor will support the shaft to keep the revs above 1700 RPM. Once load is taken off the engine,

revs will recover above 1700 RPM and charging will start automatically. Charging current constantly

varies depending on the excess power available.
If the electric system fails to function (controller failure, motor failure, etc) the booms can be operated in

diesel only mode. However, this mode is only for low duty functions and for assisting to recover the

booms back to the transport position. Full boom function performance is only available in electric only or

hybrid modes.

5.4

Drive System

5.4.1

Hybrid

The drive system uses 60L/min maximum flow from the pump. The table below describes the available

driving modes.

Electric Only Mode

All the listed driving modes are available in electric only operation. Available power is reduced to 8kW and

hence performance is reduced. It is advisable to switch to hybrid mode when high power demand is

required e.g. off road driving.

Hybrid Mode

In hybrid mode a full 23kW of combined power is available for machine functions. In this mode the

machine consumes battery power to support the engine when required and regenerates battery power

when the function duty is low. Under continued high duty function for long periods the battery levels will

be significantly reduced to support the high power requirement. Under such conditions it will be normal

to have to recharge the battery levels prior to electric only use.
