Title:
STUD TYPE CARGO LIFTING SLING
Document Type and Number:
Japanese Patent JP3222722
Kind Code:
B2
Abstract:
PURPOSE: To facilitate a job for positioning in time of opening or closing a stud by forming a circular curved surface in the upper end of a stud coupling member as well as to engage this curved surface with that of a top plate, in this lifting sling which suspends a chain block or the like on the top plate supporting three to four pieces of studs in a state that their upper ends are aggregated.
CONSTITUTION: Three projections are formed on a top plate 1 in the radial dorection trisectioned from the center O, and each circular curved surface 1a is formed upward in respective projection tips in the radial direction. A lifting ring 2 is clamped tight to a lower side of the central part formed in plane form, of the top plate 1 by means of a nut being screwed. In addition, a projecting curved surface 4a being engaged with an inner part of the curved surfaces 1a of the projections is installed there, forming each stud coupling member 4b, and a boss part 4e projectingly installed on the curved surface 4a is engaged with a radial long hole 1b formed in the curved surface 1a. A conjunction between the top plate 1 and a coupling member 4 is carried out by way of screwing a thread member 7 into the boss part 4e, while the joining of a stud 5 is carried out by inserting a lock pin 8 after being installed in this coupling member 4.
