The invention provides a load hanging device for a mechanical lifting
tower crane, which relates to the technical field of load hangers, and comprises a lifting hook body, a clamping plate, a protective sleeve, a balance sleeve and a traction piece, two sets of opposite side supporting pieces are installed at the lower hook end of the lifting hook body, one end of a pull
rope is connected with the bottom side of the outer end of a tongue blocking piece, the other end of the pull
rope is connected with the bottom end of a side connecting frame on the side supporting pieces, and the top end of the lifting hook body is further connected with a top connecting rod which is inserted in the middle of a protective sleeve in a penetrating mode and clamped through two sets of clamping plates. The balance sleeve is sleeved at the middle end of the top connecting rod through the key shaft hole, the lower end of the traction piece is of an
inverted T-shaped structure and is provided with an
insertion cavity, and the top connecting rod penetrates into the
insertion cavity through the inner
insertion hole and is clamped through a nut. And when the heavy object falls to the ground, the tongue blocking piece is automatically separated from the opening end of the lifting hook body, so that the problems that when the heavy object is lifted, the lifting
rope is in hard friction with the bottom end of the inner side of the lifting hook body, the lifting hook body sometimes rotates along with the lifted heavy object, and the lifting safety is influenced are solved.
