rig for removing the rod from a hydraulic cylinder

[Frank S]

What's a Siamese cylinder? I've heard "simo" cylinders on big equipment, but that's a bastardization of simultaneous with respect to big industrial hydraulic presses. I did a search online and can only find reference to engine blocks where cylinders have no water jacket between them. What are these cylinders used for?

Just incase someone doesn't read the other thread Siamese cylinders are matted side by side with the rods facing in opposite directions. some manufactures do this instead of having to use a double acting telescopic cylinder. Siamese double acting cylinders are simpler to make than a telescopic cylinder which is also required to exert force while retracting also you can achieve a longer stroke in a shorter area than having to use a single long cylinder
