Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gantry hook electric rotary lifting tools, and specifically relates to a gantry hook electric rotary lifting tool. Background Technique
[0002] A lifting tool refers to a device for lifting heavy objects in a hoisting machine. The most commonly used lifting tools for lifting finished items are hooks and slings. There are also other lifting tools such as lifting rings, lifting suction cups, clamps, and forklift tines, which are widely used in the hoisting and lifting industry. A lifting tool refers to a device for lifting heavy objects in a hoisting machine. In bridge construction, it is often necessary to hoist structures such as steel bars, steel plates, steel girders, and precast slabs. However, in the process of using existing lifting tools in bridge construction, the following technical problems exist: Due to the limited construction site for hoisting, most existing lifting tools are difficult to complete in-situ rotation, and the structure of the lifting tool is complex and the cost is high. At the same time, during the specific construction hoisting process of the bridge, for objects of different sizes, the applicable range of the lifting tool is small. If the lifting tool is replaced for hoisting, there are problems such as slow construction progress and high labor costs. Most existing lifting tools generally have poor stability with two-point force when hoisting heavy and long objects. There are problems of poor stability. During the hoisting process, both the lifting tool and the object are prone to deviation or sliding. If the object slips from the lifting tool, it poses a major safety hazard to the safety of workers and the bridge, and at the same time, it will also cause huge economic losses.
