Abstract

A safety pick-up sling for handling tubular goods including a formed saddle having an arcuate recess to engage the tubular goods and having a steel cable secured centrally to the top of the saddle and extending twice beneath the saddle to encompass the goods. The steel cable has its opposite free ends secured to an equalizing lifting ring for attachment to a lifting cable. The lifting action of the lifting cable on the equalizing ring tightens the cable to the saddle to hold the tubular goods therein.

[57] ABSTRACT A safety pick-up sling for handling tubular goods including a formed saddle having an arcuate recess-t0 engage the tubular goods and having a steel cable secured centrally to the top of the saddle and extending twice beneath the saddle to encompass the goods. The steel cable has its opposite free ends secured to an equalizing lifting ring for attachment to a lifting cable. The lifting action of the lifting cable on the equalizing ring tightens the cable to the saddle to hold the tubular goods therein.

4 Claims, 5 Drawing Figures TUBULAR SAFETY PICK-UP SLING BACKGROUND OF THE INVENTION FIELD OF THE INVENTION The present invention relates to safety pick'up slings for tubular goods such as pipes.

SUMMARY OF THE INVENTION A formed steel saddle is provided with an actuate BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevation of the invention;

FIG. 2 is a front elevation of the invention;

FIG. 3 is a horizontal sectional view, taken along the line 3-3 of FIG. 1, looking in the direction of the arrows;

FIG. 4 is an enlarged fragmentary vertical sectional view, taken along the line 4-4 of FIG. 3, looking in the direction of the arrows; and

FIG. 5 is an enlarged transverse sectional view, taken along the line 55 of FIG. 4, looking in the direction of the arrows.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail, wherein like reference characters indicate like parts throughout the several figures, the reference numeral indicates generally a tubular safety pick-up sling constructed in accordance with the invention.

The sling 10 includes a metallic saddle 11 having a semi-cylindrical central portion 12 connected to a pair of opposed generally horizontal flanges 13, 14.

The flange 13 has a pair of spaced parallel elongate apertures 15, 16 extending therethrough and the flange 14 has a pair of elongate spaced apertures l7, 18 formed therein. The apertures 15, 17 are arranged in aligned relation and the apertures 16, 18 are arranged in aligned relation. A generally U-shaped handle 19 is integrally secured to the arcuate portion 12 of the saddle 11 and extends transversely thereacross to permit the saddle 11 to be moved from place to place by hand.

A cable clamp tube 20 is welded to the actuate portion 12 of the saddle 11 at the top thereof and arranged to extend in a line between the aperture 16 and the aperture 17 as can be clearly seen in FIG. 3. A semicylindrical cable jaw 21 is positioned in the cable clamp 20 and a set-screw 22 extending through the cable clamp 20 is adapted to press the jaw 21 in clamping engagement with a cable 23 which extends through the clamp 20.

The cable 23 has its central portion clamped in the cable clamp 20 and has loops 24, 25 formed on its opposite ends. An equalizing lifting ring 26 is provided with a pair of rings 27, 28 rigidly secured thereto internally thereof. The loop 24 loops through the ring 27 and the loop 25 loops through the ring 28. An attaching ring 29 extends through the lifting ring 26 to attach the sling 10 to a lifting cable.

In the use and operation of the invention the cable 23 is loosened so that the portions thereof which extend down through the apertures l5, 16, 17 and 18 may engage about a tubular object such as a pipe 30. Lifting pressure is then brought to bear on the lifting ring 29 causing the cable 23 to tighten about the pipe 30 so that the pipe 30 can then be lifted safely.

When it is desired to carry the sling 10 from place to place it may be grasped-by the handle 19.

Having thus described the preferred embodiment of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.

What is claimed is:

l. A safety pick-up sling for handling tubular objects comprising a saddle having a central arcuate portion for engaging the tubular objects, a cable clamp secured to the top of said saddle, a cable releasably secured intermediate its opposite ends to said cable clamp on said saddle and adapted to encompass a tubular object engaged against said saddle, and means attached to opposite ends of said cable for tightening said cable against a tubular object and the saddle for lifting the tubular object.

2. A device as claimed in claim I wherein the means connected to the free ends of said cable comprises an equalizing lifting ring, said ring including a pair of rings secured to said cable and rigidly secured internally of said lifting ring.

3. A device as claimed in claim 1 including a handle rigidly affixed to said saddle for carrying said sling.

4. A device as claimed in claim 1 wherein said cable extends through a plurality of spaced apart apertures in said saddle to extend twice around a tubular object clamped against said saddle.

Claims (4)

1. A safety pick-up sling for handling tubular objects comprising a saddle having a central arcuate portion for engaging the tubular objects, a cable clamp secured to the top of said saddle, a cable releasably secured intermediate its opposite ends to said cable clamp on said saddle and adapted to encompass a tubular object engaged against said saddle, and means attached to opposite ends of said cable for tightening said cable against a tubular object and the saddle for lifting the tubular object.

2. A device as claimed in claim 1 wherein the means connected to the free ends of said cable comprises an equalizing lifting ring, said ring including a pair of rings secured to said cable and rigidly secured internally of said lifting ring.

3. A device as claimed in claim 1 including a handle rigidly affixed to said saddle for carrying said sling.

4. A device as claimed in claim 1 wherein said cable extends through a plurality of spaced apart apertures in said saddle to extend twice around a tubular object clamped against said saddle.
