PROBLEM TO BE SOLVED: To provide the shape of a hook for a heavy goods hoisting and conveying device and hook receiving part, having no danger of coming off and dropping even if hoisting the heavy goods, and enabling a hook to accurate ly enter the hook receiving part regardless of turning even if the hook turns to freely hoisting and detaching. SOLUTION: In this heavy goods conveying device for hoisting and conveying the heavy goods, the hook receiving part C fitted to the heavy goods D is characterized in that L-shaped metal fittings 3 are disposed like a square with the tips thereof pointed toward the center, the L-shaped metal fittings and a base metal fitting 4 are firmly fixed to form a U-shape, the tip of each L-shaped metal fitting is machined to be spherical so that the spherical crown-like hook tip 2 is housed therein, the hook tip 2 is shaped like a spherical crown, narrower than the width E between two L-shaped metal fittings and lower than the height F of the neck part of the L-shaped metal fitting, and the body 1 connected to the spherical crown-like hook tip 2 is integrated with the hook tip 2.
