4.5. Main control valve
An Effer remote-controlled crane cannot be operated from the main control valve, but only through
a controller. Thus, the main control valve becomes the control station only for emergency operation
(refer to the section “Emergency operation” for more information).
The speed of a function corresponds to the extent of the lever movement, regardless of the load
and other functions, as long as the oil flow is sufficient. When the oil flow is insufficient, one or more
functions might reduce their speed.
When the controller is used, the oil flow is allocated by means of automatic flow sharing.
In the inlet side, there is also the HPCO (High Pressure Carry Over), a deviating element that
sends the oil to the crane or to the stabiliser valves block.
4.6. Different stabiliser control valves
Different stabiliser control valves that you can find on the cranes:
• Stabiliser control valves with emergency screws.
• Stabiliser control valves with emergency levers.
An Effer remote-controlled crane cannot operate the stabiliser system from the stabiliser control
valve, but only through a controller. Thus, the stabiliser control valve becomes the control station
only for emergency operation (refer to the section “Emergency operation” for more information).
4.7. User Interface with LEDs [option]
NOTE
The type of interface available on your crane depends on its configuration.
Buttons:
• (A) ON/OFF button. You hear a sound when you activate
it.
• (B) Emergency stop button
• (C) Reset LED
• (D) Horn (manual activation)
• (P) Crane cylinders pressure LEDs
• (S) Stabiliser system cylinders status/position
• LED OK:
◦ Green light on: the crane is ready to work.
◦ Green light flashing: the crane is not ready to work.
• LED Fault:
◦ Red light on: there is a fault.
