Abstract
A serial, multi-unit hydraulic system which utilizes a single hydraulic fluid circuit each for extending and retracting all constituent hydraulic units. The fluid circuit for retraction of a remote hydraulic unit extends through intervening, primary hydraulic unit(s), and, after retraction of the remote hydraulic unit, provides retraction oil flow to primary hydraulic unit(s). Control valves effect a prescribed sequence of extension and retraction of the constituent hydraulic units, without involving separate, external control apparatuses.
