Cylinder types
Piggy-back cylinders are a design solution used in applications to maximise stroke length where space constraints or specific operational requirements exist.
This design involves the welding or yoking of two cylinders together in the opposite direction to each other allowing them to work in tandem.
A useful feature of piggy-back cylinders is the fact they can be plumbed to provide consistent force throughout the whole stroke movement, ensuring high retraction forces.
Using centrally mounted yokes the master and slave cylinder are welded or bolted together giving extended stroke reach whilst maintaining compact closed centres.
Annular porting (through hollow cylinder rod in master cylinder) eliminating the chance of feed hoses not retracting properly.
Fluid is simply piped from the master to the slave cylinder, giving seamless second-stage actions.
