Crane Limitations & Load ChartsCrane Limitations & Load Charts- Operators must be aware of different load
charts, and reductions.
- Numerous reductions must be made for items including;- Hook block
- Headache ball
- Jib
- Rigging

- Load charts differ if;- hoisting over the front or side
- On rubber, half outrigger, full outrigger
