Z-Lock Master and Idler Cylinders
The Z-Lock mechanism requires a large force to achieve sufficient clamping pressure on all
present towers simultaneously.
Maximum applied force (less friction) through the mechanism is 14, 800 N with both Master
and Idler Cylinders are active.
The reduced force generated with just one pneumatic cylinder active (less friction) is: 7,792N
