Furthermore, in order to avoid that an operator cannot reach the tail of the hoisting cross rod after the object is hoisted by the lifting hook due to too large hoisting height, the other end of the hoisting cross rod is also provided with a hoisting rope; the sling is made of a thick rope with high flexibility and good comfort, the toughness meets the requirement of no breakage in the process of hoisting a heavy object, and the length meets the requirement that the lifting hook can hoist the heavy object.

Has the advantages that: the utility model discloses equipment is simple, simple to operate, with low costs, efficient superiority, and generally little medium-sized professional team all can be from the beginning to the beginning, can direct application on narrow construction platform such as side slope. In particular, the method comprises the following steps of,

(1) the construction cost is saved: the waste of crane resources is saved, the investment of equipment and electric power of a project is reduced, and in addition, the cost for building a platform is saved;

(2) the construction progress is accelerated: by adopting the traditional construction scheme of climbing tigers for hoisting and manual carrying, the construction period is long, the times of equipment carrying and dismounting are more, the construction progress is slow, the visual nodes of the project cannot be met, and after the lever simple hoisting tool is adopted, the component hoisting is accurate and in place, a large amount of carrying time is saved, the construction efficiency is improved by 50 percent, and the originally planned construction period of 13.5 days is finished in only 6 days;

(3) the safety risk is reduced: the risk that operating personnel walk in the high altitude in the transverse precast block in the vertical hoisting process of the traditional creeper is avoided, the risk that the operating personnel collide with the hoisting personnel due to overlarge cable swing in the hoisting process of the crane is avoided, and the construction safety is ensured.
