Max. capacities in metric tonnes do not exceed 75% of tipping load.
Capacities in duty cycle operation are for reference only and are not programmed in the LMI system.
The size of the bucket has to be determined according to local conditions.

500 kN
Rope diameter

75.8 t
1) Lifting a load exceeding the line pull of one winch is only allowed
if it can be ensured that each individual winch is not overloaded.
When working with a mechanical 2-rope grab the total load
to be lifted is limited by the line pull of one winch.
Rigging and ropes are part of the load.
2) Max. capacities in metric tonnes do not exceed 75% of
tipping load. Crane standing on fi rm, horizontal ground.
Capacities in duty cycle operation are for reference only and are not programmed in the LMI system.
All loads and counterweight confi gurations are max. values and must not be exceeded.
Weight of additional equipment on boom (e.g. walkways, hose drums etc.) must be deducted to get the net capacity.
