Abstract

The invention relates to the technical field of lifting devices, and particularly relates to a rotatable type lifting device. The rotatable type lifting device comprises a cross beam, wherein a suction disc type lifting ring is arranged at the central position of the cross beam, the left side and the right side of the cross beam are respectively provided with two protective sleeves, and the cross beam does rotational motion under the action of a rotary motor. The rotatable type lifting device disclosed by the invention can enable a lifting tool to follow to do the rotational motion by virtue of the action of the rotary motor when encountering windy weather, so that the wind resistance is counteracted.

Description

technical field [0001] The invention relates to the technical field of sling devices, in particular to a rotatable sling device. Background technique [0002] The spreader refers to the device for lifting heavy objects in the hoisting machinery. The most commonly used spreader for lifting finished items is the hook, and others include lifting rings, lifting suction cups, clamps and forks. It is widely used in the lifting industry. [0003] The existing spreader has some structural defects, especially in windy weather. Once the wind blows, the spreader will be blown to this side or even under the negative pressure of the wind. The resistance increases and is forced to land, and sometimes safety accidents can occur. Contents of the invention [0004] The technical problem to be solved by the present invention is: In order to solve the problems raised in the background technology above, the present invention provides a rotatable sling device, which can make the sling Fol...
