Load chart for main boom

Notes for QY 25C load chart：

1. The values in the tables refer to the max. lifting capacity of truck crane that is set horizontally on flat and solid ground. The

values above the block lines in the tables depend on the strength of truck crane, while those below the block lines depend on

the stability of truck crane.

2. The parameters above are obtained with fully-extended outriggers, and the lifting capacity in the situation that the truck

crane is in the rear and side must be obeyed. Don’t have the truck crane lift without any outrigger extended.

3. The values listed in the tables are max. values permitted, including the weight of hook and spreader(main hook: 360kg;

auxiliary hook: 90kg).

4. The ranges in the tables refer to the actual horizontal distance between the hook center to slewing center after lifting.

5. The lifting capability of single sheave at the boom tip is the same as the working condition of 33.5m boom, and its max.

lifting capacity≤3.5t.

6. If the jib is installed at the jib of main boom, the lifting capability for each working condition in the table shall be reduced by

550kg correspondingly according to the lifting capability of main hook.
