one or more reinforcing arms connected to the one or more valve interfacing surfaces, the one or more reinforcing arms positioned so as to underlie the compressor valve when the one or more valve interfacing surfaces interface with the outer surface of the compressor valve;
one or more tool lifting arms directly connected to the one or more reinforcing arms at a first end of the one or more tool lifting arms; and
a lifting mechanism connected to the one or more tool lifting arms at a second end of the one or more tool lifting arms, the heavy compressor valve removal tool adapted to lift the compressor valve when the one or more valve interfacing surfaces interfaces interface with the outer surface of the compressor valve.
2. The tool of claim 1 , wherein the one or more valve interfacing surfaces comprise an extended arcuate surface to interface with an outer arcuate surface of the compressor valve.
3. The tool of claim 2 , wherein the extended arcuate-shaped interface surface comprises a substantially annular shape, and wherein the one or more reinforcing arms connect to a medial portion thereof and extend substantially across the diameter of the annular shape.
4. The tool of claim 3 , wherein the lifting mechanism comprises an industrial crane.
5. The tool of claim 3 , wherein the one or more reinforcing arms comprises a beam member arm having one or more of: (a) a plurality of openings formed in the beam member arm; and (b) a skeletal structure, to thereby reduce the weight of the beam member and overall weight of the tool and yet strengthen the one or more valve interfacing surfaces when lifting the compressor valve.
6. The tool of claim 3 , wherein the substantially annular shape of the extended arcuate-shaped interface surface comprises a ring to interface with a similarly-sized, ring-shaped outer surface of the compressor valve, and wherein the one or more reinforcing arms comprises a reinforcing arm that substantially bisects the ring of the tool.
7. The tool of claim 1 , wherein the one or more valve interfacing surfaces comprise a plurality of arcuate-shaped interfacing surfaces to interface with a plurality of outer surface locations around the compressor valve, wherein at least portions of one or more of the plurality of arcuate-shaped interfacing surfaces are positioned so as to underlie the compressor valve when the one or more valve interfacing surfaces interface with the outer surface of the compressor valve.
8. The tool of claim 1 , wherein the one or more reinforcing arms have a square cross-section.
9. A method of lifting a heavy compressor valve with a heavy compressor valve lifting tool, the method comprising:
positioning a valve interfacing surface of the heavy compressor valve lifting tool adjacent an outer surface of a perimeter of a compressor valve, such that the valve interfacing surface is positioned so as to underlie the compressor valve when the valve interfacing surface interfaces with the outer surface of the compressor valve, the valve interfacing surface comprising one or more arcuate-shaped interfacing surfaces having a curvature complementary to a curvature of the outer surface of the compressor valve;
securing the valve interfacing surface of the heavy compressor valve lifting tool against the outer surface of the compressor valve; and
moving the compressor valve away from an associated compressor with a lifting mechanism connected to the heavy compressor valve lifting tool;
wherein the heavy compressor valve lifting tool comprises:
one or more reinforcing arms connected to the one or more valve interfacing surfaces, the one or more reinforcing arms positioned such that at least portions of the one or more reinforcing arms underlie the compressor valve when the one or more valve interfacing surfaces interface with the outer surface of the compressor valve;
one or more tool lifting arms directly connected to the one or more reinforcing arms at a first end of the one or more tool lifting arms.
10. The method of claim 9 , wherein the heavy compressor valve lifting tool comprises:
the lifting mechanism connected to the one or more tool lifting arms at a second end of the one or more tool lifting arms, the heavy compressor valve removal tool adapted to lift the compressor valve when the one or more valve interfacing surfaces interfaces interface with an-the outer surface of the compressor valve.
11. The method of claim 10 , wherein the one or more valve interfacing surfaces comprise an extended arcuate surface to interface with an outer arcuate surface of the compressor valve.
12. The method of claim 11 , wherein the extended arcuate-shaped interface surface comprises a substantially annular shape, wherein at least a portion of the extended arcuate-shaped interface surface is positioned so as underlie the compressor valve when interfacing with the outer surface of the compressor valve, and wherein the one or more reinforcing arms connects to a medial portion of the arcuate-shaped interface surface and extends substantially across the diameter of the annular shape.
13. The method of claim 12 , wherein the lifting mechanism comprises an industrial crane.
14. The method of claim 12 , wherein the one or more reinforcing arms comprises a beam member arm having one or more of: (a) a plurality of openings formed in the beam member arm; and (b) a skeletal structure, to thereby reduce a weight of the beam member arm and an overall weight of the tool and yet strengthen the one or more valve interfacing surfaces when lifting the compressor valve.
15. The method of claim 12 , wherein the substantially annular shape of the extended arcuate-shaped interface surface comprises a ring to interface with a similarly-sized, ring-shaped outer surface of the compressor valve, and wherein the one or more reinforcing arms comprises a reinforcing arm that substantially bisects the ring of the tool.
16. The method of claim 10 , wherein the one or more valve interfacing surfaces comprise a plurality of arcuate-shaped interfacing surfaces to interface with a plurality of outer surface locations around the compressor valve.
