A work stand specially designed for supporting and aligning the various components of a vertical turbine pump during assembly or disassembly. A plurality of support tables are mounted at longitudinally spaced positions along a stationary bed frame for independent powered vertical adjustment. Roller support cradles are carried by each table to supportingly engage the pump at longitudinally spaced positions to support the various parts of the pump in coaxially aligned relationship with each other. The cradles may be adjusted longitudinally of their tables, and a series of bores spaced longitudinally along the bed frame provide for the mounting of stationary clamp assemblies upon the bed frame between the tables. A powered elevating platform at one end of the bed provides a support for the discharge head of the pump, or alternatively a support, a support cradle, or stationary clamp. Mounting lugs located at longitudinally spaced positions on the bed frame provide a mounting device for mounting a hydraulic cylinder at selected positions longitudinally along the bed frame so that the cylinder can be employed to power a chain wrench operating on various elements of the pump.

A workstand for supporting and aligning components of a vertical turbine pump during assembly or disassembly comprising an elongate horizontally extending bed frame, a plurality of support cradles mounted at longitudinally spaced positions on said bed frame, each of said cradles comprising a cradle frame and at least a pair of support rollers mounted for free rotation on said cradle frame about spaced parallel horizontal axes extending longitudinally of said bed frame and symetrically disposed on opposite sides of a common vertical plane extending longitudnally of said bed frame, said rollers being operable to supportingly engage cylindrical positions of components of a vertical turbine pump to maintain said components in alignment with each other with the axis of said components lying in said vertical plane, means for independently vertically positioning each of said cradle frames relative to said bed frame, means for independently longitudinally positioning each of said cradle frames relative to said bed frame, and a shaft support assembly for supporting a shaft projecting coaxially from a pump component supported on at least one of said cradles, said shaft support assembly comprising lower frame means adapted to be seated upon the support rollers of one of said cradles, and upper frame means having a longitudinally extending shaft receiving notch of V shaped transverse cross section.
