Abstract
A pipe flange lifting device for supporting and leveling a blind flange during installation onto a pipe end. The device comprises a pair of closed fittings having a plurality of apertures through which to place a first and second lifting bolt. The fittings are positioned on opposing sides of a pipe flange and rotate freely with respect to the pin prior to installation, whereafter the lifting bolts fitted through the flange and opposing fittings for stable support during operation. The lifting bolts comprise a pair of bolts inserted into eyes of the flange prior to the lifting operation. Spacers along the pin allow the fittings to be separated by a desired distance and prevent pinch points due to fitting inclination. The pin includes an attached crane hoist fitting for lifting the assembly and a secured flange during flange installation.
Claims6
A pipe flange lifting device, comprising:
- a set of opposing fittings separated by a given offset distance;
- said fittings having a plurality of apertures therethrough adapted to provide a closed region having a ledge to support a lifting bolt;
- said fittings rotatably attaching to a common pin spanning said offset distance;
- said pin having a hoist fitting along its length for connecting said device to a lifting apparatus;
- a plurality of spacers along said pin between said hoist fitting and said fittings to adjust said offset distance and prevent pinch points.
A pipe flange lifting device, comprising:
- a set of opposing fittings separated by a given offset distance and having a generally triangular shape,
- said fittings having a plurality of apertures therethrough adapted to provide a closed region having a ledge to supporting lifting bolts of varying pitch;
- said plurality of apertures comprising a pair of lower apertures and a singular upper aperture;
- said fittings rotatably attaching to a common pin spanning said offset distance;
- said pin having a hoist fitting along its length for connecting said device to a lifting apparatus.
