ABSTRACT:
A remote-controlled loading hook is provided with a hook-shaped means having its upper end journalled on a pin in the upper portion of a casing. The hook-shaped means is adapted to be swung with its lower end, shaped as a hook, into the casing. The casing is freely suspended in a cable, a chain or the like. The casing has an opening in its lower part and the carrying hook, which has a locking abutment, is adapted to bridge said opening. A seat is arranged on either side of the opening to support the carrying hook in position of use. The hook-shaped means is suspended on the pin in such a way that at the lifting of the casing and the loading of the hook-shaped means the latter can move in vertical direction relative to the casing to a position in which one of the seats catches behind the locking abutment of the hook.
