3.3.3. Maximum load
Lifting capacity
Your crane has a certain lifting capacity, expressed in kNm or tm. 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 Progress system switched off.
NOTE
The lifting capacity indicated in the standard crane and crane + JIB load chart does
not include the weight of the hose reel, winch, grapple, exchange solenoid valves,
manual extensions and any other accessories fitted on the boom system.
Load plate
On the plate is the maximum weight that you may lift at a given outreach, with the 1st boom in the
optimum position. In the Technical Data, you will find these values for your crane.
• (A) The maximum capacity of the crane.
• (B) The maximum capacity of the JIB (if
fitted).
• (C) The maximum load that the stabiliser
leg can apply to the ground.
• (D) The position of the stabiliser
extensions according to the load plate.
NOTE
Align the yellow arrows signs located on
the column and on the 1st boom to reach
the maximum load values as the load plate
shows.
