Abstract

The invention provides a tackle. The tackle comprises a mounting plate, a pulley shaft arranged on the mounting plate, a pulley rotationally arranged on the pulley shaft, and two hooks which are pivoted at two ends of the mounting plate, wherein the tackle can be in a first hoisting state and a second hoisting state when the hooks pivot around the mounting plate, and one of the hooks is used for hoisting when the tackle is in a first hoisting state, and two hooks are used for hoisting when the tackle is in a second hoisting state. According to the tackle with two hooks, two different maximum lifting loads can be acquired due to allocation of the two hooks, and the tackle is two times of the existing tackle in the maximum load capacity under a condition that a large hook is not replaced; compared with the existing tackle, the tackle has reduced purchase cost and reduced dead load, the two different maximum lifting loads can be selected rapidly and conveniently, a part does not need to be replaced, and the operating convenience and the working efficiency are improved.

Description

technical field [0001] The invention relates to a hoisting tool, in particular to a hoisting block. Background technique [0002] The block is an important lifting tool for lifting and operating objects. Existing tackle such as figure 1 , 2 As shown, it includes a pulley 1, a mounting plate 2 and a hook 3, the pulley 1 is arranged on the mounting plate 2, a hook 3 is fixed at one end of the mounting plate 2, and a rope head fixing point S is set at the other end. Since the existing block is equipped with only one hook 3, assuming that the rated lifting capacity of the hook 3 is Q, the weight of the heaviest item that can be lifted by this block is also Q. If it is necessary to lift heavier items, the block cannot meet the lifting requirements, and the hook with a larger rated lifting capacity can only be replaced. In fact, the cost of the hook is the main component of the cost of the tackle. The weight of a hook with a rated lifting capacity of 2Q is much greater than t...
