2.7. LHV Load holding valves
All cylinders are equipped with load-holding valves as a
safety device. After a crane movement they hold the crane
in position, also in the unlikely event of a burst hose.
If there is a leak or a component fractures, such as a pipe,
hose or a coupling, the load-holding valves will stop the
booms from collapsing down, even when the hydraulic
system is switched off, and you operate a particular crane
function.
To operate a hydraulic cylinder equiped with a load holding
valve, an opening pressure is required.
