Notes:

1.The actual lifting capacity must be deducted from the rated lifting capacity in this table by the weight of the hook, sling and wire rope wrapped around the hook and boom head.

2.The rated load in the table is the value when the load is lifted slowly and steadily on a horizontal hard ground and the non-travel lifting work is performed.

3.The rated load in the table is based on the calculation value of the main boom section without the tower arm back plate, tower arm guide pulley and arm end single pulley.

4.The tower arm back plate needs to be removed from each boom section, and the tower arm guide pulley needs to be removed from the top section of the main boom.

5.The waist rope needs to be used for the combination at the "*" when the main boom length exceeds 71m, and it is recommended to use a wedge to assist the boom when the main boom length exceeds 74m.
