Tongs shall be of the lever, double jaw, open caliper type with compound leverage grip. The jaws or liners shall grip the outside of the pipe at a point b
9、elow the centerline of the pipe. The tongs shall be constructed to provide a nonmanual positive release from the pipe after the pipe is set down, and the hoisting line is slacked off. Tongs shall be of a configuration suitable for operation in a close side clearance for handling in a narrow trench.
10、When specified (see 7.2), liners for tongs shall be provided for handling pipe of outside diameter as specified (see 7.2). The tongs shall comply with the requirements of ANSUASME B30.20. 3.2.1 Class I. Class I tongs shall be of heat-treated aluminum alloy as specified 3.6.2; and shackles, links, an
11、d rings shall be aluminum-alloy forging as specified in 3.6.3; or shackles shall be of cast-aluminum alloy as specified in 3.6.2. 3.2.2 Class II. Class It tongs shall be fabricated of steel plate a specified in 3.6.4, or cast steel as specified in 3.6.5; shackles, links, and rings shall be steel for
12、gings as specified in 3.6.6; or shackles shall be steel castings as specified in 3.6.5. Fulcrum pins shall be brass as specified in 3.6.7. 3.3 Performance. The tongs shall be capable of lifting and holding a gross load of weighted pipe of not less than the following: Size 4 - 1,250 pounds (lb) (566

The weighted pipe shall remain secure aRer being swung in an arc. The tongs shall be capable of releasing the weighted pipe after being sat down by slacking off the
14、 lifting line without manual manipulation of the tongs. 3.4 Finish. Surfaces normally painted in good commercial practice shall be cleaned, treated, and painted. Unless otherwise specified (see 7.2), the color of the finish coat shall be the manufacturers standard. 3.5 Markina for identification. To
