Main control valve
The crane can be operated from the main control
valve, but as soon as you have selected remote
control operation, it is impossible to operate the
main control valve levers.
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 remote control is used, the oil flow is
allocated by means of PFD.
