Spatial combination of slider crank mechanisms 1

The top plate moves along a vertical straight line without any runway.
This can be considered a Sarrus linkage.
Dead position problem: can occur with the 3 slider crank mechanisms of green cranks because for them the pink top plate is the driving link.
The inertia of the green cranks helps them to overcome the dead positions.
