6.1.8 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 swing
angle and boom length condition (#2784) are satisfied, the lowering can be performed to the stroke end
without a stop.
Stop condition: Boom angle
≤ Boom lowering stop angle (#2784), and in the crane status other than the one
specified by data (#2784)

The crane status (traveling retraction) specified by (#2784) is as follows:
Boom length (m) Left swing limit (°) Right swing limit (°) Boom angle (°)

6.1.9 Elevation Upper Limit
With 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 raising stroke end is reached.
When the raising stroke end is reached, an overload status is reached, and then the lowering operation
becomes prohibited, making the stowing impossible. Therefore, at the angle (#2783) or more than the ones
specified in the table below, the elevation lowering is allowed even when the moment value is 100% or more.
Stop condition: Detected boom angle
≥ Boom raising stop angle (#16719)
