Operating principle
1 - Description
Hydraulic energy to perform machine movements is provided by an electric pump.The operating speed
of the pump is governed by a speed regulator.
The controls and start-up of the electric motor are powered by battery.
To protect the staff and the machine, safety systems forbid the use of the machine beyond its
capacities.
These security systems immobilize the machine and neutralize the movements.
2 - Safety devices
2.1 - ACTIVATION OF CONTROLS
The controls must be validated by a 'Dead man' system to activate the different movements.
The 'Dead man' system depends on the machine configuration :
• Joystick handle.
• Pedal.
• Validation button.
2.2 - DRIVING SPEED (MINIMUM)
All driving speeds are authorized when the machine is stowed ( machine in
lowered position).
The only speed allowed when not in stowed position is microspeed.
Poor knowledge of the characteristics and operation of the machine can lead the operator to think that a
normal safety operation is a malfunction.
