ABSTRACT:
A casing for hydraulic lifts and the like of the type buried in the ground. The part of the casing deeply buried in the ground may be subject to corrosion and electrolysis, which is quite common in many soils, and is made from a strong, fiberglas composite material. The part of the casing not subject to corrosion is metallic. Flanges connect the two parts in end-to-end sealed relation with respect to each other and the seals and guides for the plunger are carried in the metallic part of the casing. A non-metallic bulkhead is bonded to the bottom of the fiberglas composite casing and may have a port opening through its bottom wherein the lift is a semi-hydraulic lift as is common with passenger car lifts.
