6.1.1 100% lifting performance stop

When the moment load 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 moment load ratio (load ratio) becomes as follows:

Main boom with jib judgment: (1) and (2)

(1) Jib extension detection is in "extension" status (Di7: OFF).

(2) "Boom operation" is set with AML.

Code at stop: W0023

W0124 (For the main boom with jib)

Cancel: 100% stop cancel (Di6: ON)

Stop operation: (×: Stop operation)

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.
