WARNING
Be careful when handling loads in the high
lifting area, thus the load/tool does not come
into contact with the boom system.
WARNING
Never operate the hydraulic extensions
against a solid object when the first boom
is completely lifted. Do not try to push or
compress loads when the first boom is fully
lifted, as this could cause damage to the first
boom cylinder.
3.3.4. Maximum load moment
If your crane has reached the maximum load moment (lifting capacity), Progress gives a warning
and locks any crane movement that will increase the load moment. This is known as the maximum
limit situation.
In this situation, only the following movements are allowed:
• crane slewing (only one slewing direction is allowed to go out from the low stability area)
• 1st boom lifting (not allowed if the max performance limit is reached in a low stability area)
• 2nd boom lowering (allowed only if the 2nd boom angle is less than 30°)
• 2nd boom lifting
• extend the boom extensions (allowed only if the 2nd boom angle is under -45°)
• retract the boom extensions
• JIB lowering (allowed only if the 2nd boom Jib is positioned below the horizontal)
• JIB lifting
• hoist lowering
Lifting the load
Make sure that you always have the work in clear view. If you cannot see the load properly, you
could cause a fatal accident or serious damage.
