JPH1077193A - Safety device for handling crane hook - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent interference with a person and an object by a hooker tip end part generated at crane working time, by providing a mounting hole and a magnet in a U-shaped metal unit, in order to cover the hooker tip end part from the outside. SOLUTION: A mounting hole in a U-shaped metal unit and a magnet 3 in the inside are provided. The mounting hole is provided in a dislocation lock support shaft pin. Here, when a length of the pin is provided with no margin, by providing replaced with a long pin, the U-shaped metal unit covers a hooker tip end part from the outside, so that coming off due to inversion of a slinging wire generated in its play or the like after sling work by concealing of a hooked former step difference can be easily prevented. A suspension load is unexpectedly hooked to something, even when one sling wire is loosened to be inverted, apprehension of dislocation is eliminated, and a suspension load dropping accident by coming off can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for handling a crane hook for preventing external interference and falling off of a sling wire caused by a tip of a hacker tip of a crane hook main body.

[0002]

2. Description of the Related Art A conventional hacker disengagement prevention device is provided with a plate-like metal, and a lower end is provided so as to stop in front of the inside tip of the hacker to prevent a sling wire from falling off. It could be inadvertently or inadvertently mistaken and cause people, objects, and airborne obstacles (electric wires, etc.) to be caught. In the past, many disasters have occurred in the past due to falling of suspended loads due to inversion caused by play of the slinging wire and falling of the slinging wire.

[0003]

SUMMARY OF THE INVENTION The present invention seeks to solve the following problems by solving the following problems. (A) Prevents accidents such as accidental falls and property damage caused by inadvertently catching or catching people or objects caused by the tip of a hacker that occurs during crane operation, and preventing interference with airborne obstacles such as electric wires and high-voltage lines.
Prevent serious accidents such as electric shock accidents. (B) Prevention of serious accidents such as falling of sling wire and falling of suspended load due to reversing of sling wire.

A mounting hole 2 and a magnet 3 are provided in a U-shaped metal body 1 for covering the tip of a hacker from the outside.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS By covering the tip of a hacker from the outside, a step can be eliminated and the slinging wire can be prevented from falling off due to inversion caused by twisting, play and the like of the slinging wire. Also, interference with external objects and people can be prevented.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings and embodiments. FIG. 1 is a perspective view of a U-shaped metal body 1 in which a magnet 3 is provided inside a mounting hole 2. FIG. 2 is a view showing the mounting operation, in which the mounting hole 2 is provided on the stopper pin. At this time, if there is no room for the length of the pin, replace it with a long pin, and provide the U-shaped metal body 1 by covering the tip of the hacker from the outside so that the original step of the hook is hidden and Can be easily prevented from falling off due to the reversal of the slinging wire that occurs in the play of the slinging wire, etc., and there is no worry that the suspended load will be inadvertently caught by something and one of the slinging wires will come loose even if it turns over, It is possible to prevent a falling load accident due to falling off. In addition, the hacker's tip caused by inadvertent operation, inadvertent driving, inadvertent cueing, etc. caused by the crane work and caught up by a person or an object without being carelessly cut off by covering the tip of the hacker from the outside. Can prevent serious disasters caused by human error in a simple and inexpensive manner, and create a safer crane working environment. When used, the magnet 3 is fixed to the tip of the hacker by the magnet 3 provided inside the U-shaped metal body 1. When the ball is slung, the magnet 3 is attached to the hook body.
Since it can be fixed with, it is possible to hang a sling wire conventionally.

[0007]

As is clear from the above-mentioned embodiment, the present invention can be applied to a single hammer-shaped metal plate at the tip of a hacker, which is considered to be a source of snagging. This makes it easy, cheap and reliable to prevent interference with people and objects due to the tip of the hacker that occurred during crane operation, resulting in accidents caused by inadvertent, vague driving, inadvertent signaling, etc. Can be prevented beforehand and human error can be prevented. Also, it is necessary to prevent the fall of the sling wire by removing the slack wire by the reversal caused by the slack of the slack wire, etc. In this way, it is possible to solve human disasters caused by falling wires and slinging wires, etc., and protect the lives of workers working at construction sites from disasters. Eliminate the factors that evolve and contribute to improving safe crane work. In addition, a hard resin or a non-metal may be used as long as the material has hardness instead of the U-shaped metal body of the present invention. In addition, any shape may be used as long as the tip can be covered instead of the U-shape.
