3.1.3 Safety devices
The safety operating of the machine is controlled by the following safety systems
•
Check valves which are controlled by pressure and placed on all working cylinder
•
Pressure limiting valve for three hydraulic cycles
-
supports and rubber foots for transporting: 200 bar
-
operating the superstrucrure: 140 bar
•
Basket sensor (the superstructure is only able to operate in case of the properly
assembled basket.)
•
The bubble glass, which is placed nearby the hand control valves, will help to
bring to the level the frame
•
The switch clock for eliminating of the spontaneous starting
•
The end switches, which are in the ground plates, control the safety stabilizing
•
Sensors controlling the angle of the bottom arm
•
Sensors controlling the end position of the bottom telescope
•
FI relay (30mA),
•
EMERGENCY-STOP switch on the switchboard of the basket and the cord
controlled remote-control panel
