Machine description
Power source (Battery system)
Battery pack contains 15 units of 302 Ah Lithium Iron
Phosphate cells enclosed in steel and plastic covered
box.
Battery system is a system where all battery
management system (BMS) functions are inside the
battery pack. Battery pack includes user interface and
BMS.
Electric motors
The machine is equipped with two air-cooled,
permanently magnetized synchronous motors. One for
the propulsion system and one for the vibration
system. Each of the electric motors is powered by a
motor controller.
Electrical system
The machine has the following control units (ECU,
Electronic Control Unit) and electronic units.
• Main ECU (for the machine)
• As well as checking and control units for drive and
vibration packages (electricity)
Propulsion system/Transmission
The propulsion system is a hydrostatic system with a
hydraulic pump that supplies two motors seriell
connected.
The motors drive the front and rear drums.
The speed of the machine is proportional to the
deflection/angle of the control lever from neutral.
Brake system
The brake system consists of a service brake, reserve
brake and parking brake.
The service brake is hydrostatisc and is activated by
moving the control lever to neutral.
Reserve/Parking brake
The backup and parking brake system consists of
sprung brakes in the motors. The brakes are released
with hydraulic pressure and are operated with a switch
on the instrument panel.
Steering system
The steering system is a hydrostatic system.
The control value on the steering column distributes
the flow to the control cylinder, which actuates the
