The machine is equipped with the following safety devices:
Tab. 3-1
Periodically check the proper operation of the safety devices.
1
CONTROLS ENABLE BUTTON
Pressing the button after starting the engine enables pumping and mixing; when the hopper grid is opened the
pumping or mixing do not automatically restart, but it is necessary to press the button.
2
ENGINE COOLING FAN GRID
Fixed guard. Narrow mesh grid secured to the engine to segregate the cooling fan and prevent contact with the upper
limbs.
3
ENGINE FAN BELT GUARD
Fixed guard. Guard secured to the engine to segregate the belt that activates the cooling fan and prevent contact with
the upper limbs.
4
HOPPER GRID
Interlocked mobile guard, PL=c in compliance with EN ISO 13849-1:2008.
Avoids exposure to moving parts. The solenoid valve controlling the pumping is de-energised when the grid is
opened. When the grid is opened the moving parts stop in a very short time (less than 1 sec). The pumping can only
be started if the grid is closed and the controls enable button pressed.
5
HOPPER BASE
Fixed guard. Shaped steel sheet panels fastened with screws to the machine structure, form the hopper base and
segregate the “S” valve and the agitator device, preventing reaching with the limbs.
6
LUBRICATION WATER TANK GRID
Fixed guard. Metal grid fastened with screws to the lubrication tank, to segregate the stems of the actuators that drive
the pumping pistons.
7
PRESSURE RELIEF VALVE OF THE PUMPING HYDRAULIC CIRCUIT
They limit the maximum pressure of the circuit.
8
PRESSURE RELIEF VALVE OF THE EXCHANGE JACKS
It limits the maximum pressure of the circuit.
9
PRESSURE RELIEF VALVE OF THE SECONDARY HYDRAULIC CIRCUIT
It limits the maximum pressure of the circuit (mixing and water pump)
