Remarks
1. The lifting capacities stated are valid for lifting operation only
(corresponding with crane classification according to F.E.M.
1.001. crane group A1).
2. Crane standing on firm, horizontal ground.
3. The weight of the lifting device (hoisting ropes, hook block,
shackle etc.) must be deducted form the gross lifting capacity to
obtain a net lifting value.
4. Additional equipment on boom (e.g. boom walkways, auxiliary jib)
must be deducted to get the net lifting capacity.
5. For max. wind speed please refer to lift chart in operator‘s cab
or manual.
6. Working radii are measured from center of swing and under load.
7. The lifting capacities are valid for 360 degrees of swing.
8. Calculation of stability under load is based on DIN 15019 / part 2 /
chart 1 and ISO 4305 Table 1 + 2, tipping angle 4°.
9. The structures are calculated according to F.E.M. 1.001 - 1998
(EN 13001-1; EN 13001-2).
