Handling
The crane, shackles, eye bolts, cable, and other lifting devices must be
in good repair and capable of safely handling the weights. The crane
should be positioned so that the hook is directly over the center of gravity
of the piece to be lifted. Do not bump, push, or scrape components or
assemblies. Motor, turbine, or gear lifting lugs or eye bolts are designed
for lifting these components only. Do not lift the pump together with the
motor, turbine, or gear. Use lifting lugs when provided. Otherwise, in-
stall eye bolts with washers and nuts in the flange bolt holes and attach
lifting lines. Use care to avoid damage to the machined surfaces.
Tools and Work Area
Common millwright and pipe-fitter tools generally are sufficient to
perform vertical pump maintenance. The work area should be clean and
well lighted. Horizontal racks for dismantling and reassembly of vertical
turbine type pumps are desirable to avoid handling damage, and to
shorten turnaround time.
