6.1.1 100% Lifting Performance Stop
When the load moment ratio (load ratio) exceeds 100%, the operation in the load ratio-increasing direction is
stopped. However, for the main boom operation with jib, the automatic stop is performed when the load
moment ratio (load ratio) becomes as follows:

Special note: The load ratio exceeds 100% when the boom raising stroke end is reached.
Therefore, when the boom angle is A° or more, the automatic stop will not be performed for the boom
lowering operation even when the load ratio is 100% or more.
