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.

    本发明提供了一种机械升降吊塔用的载荷吊挂装置,涉及载荷吊具技术领域,包括:吊钩体、卡板、防护套、平衡套和牵引件;所述吊钩体的下钩端安装有两组相对的侧撑件,拉绳的一端与挡舌件的外端底侧相连,另一端与侧撑件上侧连架的底端相连,所述吊钩体的顶端还连接有顶连杆,顶连杆穿插在防护套的中间,并通过两组卡板卡位,平衡套通过键轴孔套装在顶连杆的中间端,牵引件的下端为倒T型结构,设有穿插腔,顶连杆通过内插孔穿入到插腔中通过螺母卡位。能够消除吊装重物时的旋转力,在重物落地时,挡舌件自动与吊钩体的开口端脱离,解决了重物吊起时,吊绳与吊钩体内侧底端的硬性摩擦,而且吊钩体有时会随吊起的重物旋转,影响吊装安全的问题。
