Abstract
A telescoping base support having an elongated tube and an elongated slide coaxially and slideably nested therein is provided to form a secure support for a power ram used to deflect the entrapping structure. Ideally, the power ram is pivotably mounted to a carrige which is slideably disposed about the tube of the base support and longitudinally positionable thereon.

Apparatus for spreading opposing steel structures comprising a portable base support, a power ram, and means for slideably mounting said ram on said base support, said base support having an elongated outer tube and an elongated inner slide coaxially and slideably nested within said tube and being telescopically extendible therefrom to provide said base support with a longitudinally variable dimension for abuttment against one of said opposing structures, said means for mounting said power ram comprising a carriage disposed about the outer tube, said carriage being slideable on said outer tube along the longitudinal axis of said tube for abuttment against another of said opposing structures, said carriage having means for hingedly connecting said power ram to pivot in a plane transverse to said base support.
Apparatus for separating structural parts of a vehicle comprising a portable elongated base support having a longitudinal axis, said base support being axially adjustable and adapted for abutment broadside against one of said structural parts and power means mounted thereon for slidable positioning along the length of said base support, said power means having a ram extending outwardly therefrom in a direction angular to the axis of said base support and being actuatable to forcibly abut against an opposing structural part counter to the central axis of said elongated base and pad means mounted on said support for adjustment along the length thereof for engaging the surface of said structural part.
