JP3046987U - Dome safety hook - Google Patents

Abstract

(57) [Summary] (with correction) [PROBLEMS] To provide a margin for a limit of raising a suspended load by shortening a conventional hook body. Even beginners can easily attach wires to fasteners. In addition to the conventional losing stop, a burrs stop is made at the tip of the hook to provide a double safety function. Make the crane work a little safer. [MEANS FOR SOLVING PROBLEMS] Make the main body of the hook a dome type and put the wire stopper inside. 2. Make a mid-point burr at the end of the hook. 3. Insert the fitting from below into the body of the hook. 4. Connect to the Yorimodoshi fitting next to the wire fastener. 5. Screw the end of the wire and put a stop arrow. Stop the tip and root of the wire with a U-shape with screws.

Description

[Detailed description of the invention]   Issues that the device is trying to solve 1. There is a limit even if you want to lift the load a little more by crane work. Can be shortened or work can be done with confidence. 2. If the wire of the suspended load is hanging on the hook at the spread angle, There are times when it is uneasy to check if there is a burr at the tip of the hook I can do it. 3. Conventionally, the length of the tip of the wire is considered when fixing the wire to the wire clamp Since there is no line, make a shiri inside the end of the wire and stop with a screw I made a stop arrow with the length of the metal and made a U-shaped metal fitting with a wire stopper Therefore, even beginners can safely and securely fasten the wire to the fastener.   Means for solving the problem 1. Make the main body of the hook a dome type and put the wire stopper inside. 2. Make a mid-point burr at the end of the hook 3. Put the ring type fitting in the body of the hook And connect them. 4. The wire is fastened to the wire stopper so that even beginners can safely stop it. .   The effect of the invention     1. If you make it shorter than the conventional lifting equipment, Give room to the limits.     2. In addition to the conventional losing prevention, the tip of the hook is slightly burred Make dual safety functions.     3. Even beginners can easily stop the wire with wire fasteners Above, shorten the hook body, make a burr stop at the tip of the hook, and even beginners can wire It is a device for the purpose of safety and margin that can be attached to the bracket.
