Scenarios B and C
Scenarios B and C define a learning travel if only the landside or waterside spreader is locked
in double-spreader operation.

Figure 6-20
Explanation of the diagram:
The immersion point is set at the "current hoist position (lower edge of spreader) + P108 – 2 m".
The immersion point is lowered by P108 (maximum container height) during unlocking.
The immersion point thus behaves exactly as if two twistlock bits were set.
Scenario D
Scenario D defines a learning travel if all of the containers are locked. It is applicable to all
spreader constellations.
