Dump valves
Dump valve 1.
①
Allows operation of the crane functions. To
prevent high pressure and thereby unnecessary
heating of the oil there is an automatic dumping
function. When no lever movement has been
made for 3 seconds SPACE system opens the
dump valve and the oil is returned directly to the
hydraulic tank. As soon as the operator moves a
lever the valve closes.
Dump valve 2.
②
Allows operation of the stabiliser extensions and
legs only when this valve is activated. The dump
valve 2 will be placed between the main control
valve and the stabiliser control valve. The dump
valve 2 must be activated from the SPACE
interface before the stabiliser system can be
controlled.
