DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a lifting tool for lifting H-section steel and the like.

(Prior Art) Conventionally, as a device for hoisting a building material such as an H-shaped steel or an I-beam to a desired height, there is a hanger disclosed in, for example, JP-A-49-3347.

This suspender is fixed to a main body having a pair of upper and lower support plate portions facing each other at intervals, a bracket such as a wire fixed to the upper surface of one support plate portion, and a lower surface of the other support plate portion. A supporting cylinder, a connecting rod inserted into the supporting cylinder so that the upper part can be vertically retracted between a pair of supporting plate parts, and an urging spring for urging the connecting rod to the upper supporting plate part. , And a lock mechanism for holding the connecting rod in a released state in which the upper part thereof is housed in the support cylinder against the urging force of the urging spring.

This locking mechanism stores the locking pin biased toward the connecting rod in a storage hole formed in the inner wall surface of the support cylinder, and forms a circumferential groove into which the tip of the locking pin is detachably fitted. It is configured by being provided at the tip of the connecting rod.

(Problems to be solved by the invention) By the way, in the above-mentioned conventional hanging tool, since the locking pin is housed in the housing hole formed in the inner wall surface of the supporting tube, the hanging tool is exclusively outside the diameter of the supporting tube. There was a tendency to bloat in the direction.

Therefore, when the H-shaped steel is lifted by the conventional lifting device, if the protrusion of the flange of the H-shaped steel is short, the lifting device itself easily interferes with the web part, and therefore there are not many types of H-shaped steel cross-sectional shapes that can be lifted. It was

Further, in the conventional hoisting tool, since the engaging hole of the hoisting wire is provided on the side opposite to the opening side of the main body, when the H-shaped steel is hoisted with the flange portion sandwiched between the support plate portions, the cross section of the H-shaped steel is lifted at the time of hoisting. There was a drawback that it was difficult to handle the H-section steel when it was hung because it was inclined.

In view of such a situation, the present invention makes the supporting cylinder compact and increases the types of steel that can be lifted, and
The purpose is to ensure that the section of the shape steel can be properly lifted without inclination.
