6.1.10 Elevation lower limit As for the cranes whose moment detection is the differential pressure detection type, the moment detection becomes no longer possible when the elevating stroke end is reached. This function stops the elevation before the lowering stroke end is reached. However, to achieve the traveling configuration, when the slewing angle and boom length condition are satisfied, the lowering can be performed to the stroke end without a stop. Stop condition: Boom angle ≤ Boom lowering stop angle A°. GR-130N-1
