Abstract: 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.
