ABSTRACT:
In a dry seal gasholder cylindrical storage tank with a vertically-movable piston, an improved piston leveling system includes a vertically-movable weight outside the tank and connected by equal-length cables to spaced-apart support points on the piston at different distances from the weight. An array of guide sheaves on the tank define equal-length cable paths. The cables are pivotally coupled to spaced-apart points on a coupling plate to which a pair of attachment plates on the weight are also pivotally connected. Apertures in the attachment plates and the coupling plate are disposable in registry with one another for receiving a pin therethrough when the cable attachment points are in horizontal alignment, thereby to indicate equal tension in the cables.
