2.5 SAFETY DEVICES
On no account must you tamper with the safety devices. Use of the machine is forbidden if the seals have
been removed.
Locking Devices/Pin Retainers
The hinge and stop pins on the mechanical part (outriggers, arms, etc.) and the
hydraulic parts (outriggers) are provided with locking devices to prevent them sliding
out.
Lock Valve
Posioned on each jack, these valves prevent the outrigger moving in the event
that a hose bursts or there is a drop in the hydraulic system pressure.
Pressure Valves
Located on all the hydraulic distribuon units. To prevent overloading, these relieve operang pressure
when it exceeds the maximum set-point. The valves are set and sealed by the manufacturer during
tesng and must not be altered.
B
A
This is a safety feature that prevents the boom from operang unl the outriggers are correctly deployed and also prevents
the outriggers from being retracted if the plaorm is not correctly docked.
Each outrigger has 2 micro switches (Fig A), one detects when the outrigger is deployed and has ground pressure and the
second one detects when the outrigger is un-stowed.
The plaorm docking mechanism (Fig B) is equipped with 2 micro switches, one inside the docking seat and one situated
inside the plaorm at the end of the telescopic boom. These detect when the boom is in the correct docking posion.
