CYLINDER AND PISTON ASSEMBLY Abstract A hydraulic cylinder assembly in which cylinders are separated into two coaxial cylindrical portions sealed hydraulically one from the other, one having an extensible piston therein and the other being extensible together with the extensible piston on a fixed supporting piston. In an exemplary embodiment two such cylinder assemblies are mounted to operate in opposite directions within various predetermined fixed limits of extension to control the extension of a telescopic spreader frame for handling containers to selected ones of such fixed limits. For different combinations of such fixed limits of extension in different installations, different length spacers are used in the cylinder assemblies to establish a fixed and predetermined intermediate extension between full extension and full retraction thereof. -0-
