3.3.3. Maximum load [AR+]
Lifting capacity
Your crane has a certain lifting capacity, expressed in kNm, tm or fts-lbs. This lifting capacity is also
known as the load moment. The lifting capacity is: the payload at hook multiplied by the outreach in
metres that the crane can operate at different positions. The lifting capacity of your crane
determines the maximum load your crane may lift within its working zone. However take careful
note; the greater the operating radius of the crane, the lower the lifting capacity will be because of
the weight of the boom system itself. The load plate and the load diagram on your crane show the
maximum loads you may lift in the operating reach of your crane.
DANGER
• Overloading could result in damage to the crane or in the worst case, personal
injury or death.
• Never increase a hanging load, since that may cause a load holding valve to
open and/or the vehicle to turn over.
• Never use the crane with the OLP system switched off.
