Description

Technical Field

[0001] This utility model relates to the field of crane technology, specifically a hook-type crane device. Background Technology

[0002] A crane is a mechanical device used for vertically lifting and horizontally moving heavy objects. It is widely used in many fields such as construction, port loading and unloading, mining, and manufacturing, and can greatly improve the efficiency and safety of heavy object handling.

[0003] Chinese Patent Publication No. CN 208071152 U discloses a crane for preventing cargo from swaying, including a first support plate, the number of the first support plates is two, and the lower surface of the two first support plates is fixedly connected to a support device, and the opposite surfaces of the two first support plates are provided with a first sliding groove, and a first slider is provided in the two first sliding grooves. The lower surface of the first slider is fixedly connected to the lower surface of the inner wall of the first sliding groove through an electric push rod.

[0004] The aforementioned crane uses two clamps to hold the unloaded goods in place, preventing them from swaying. However, instead of using ropes and hooks, the crane relies on an electric actuator to move a slider to lift the goods. This limits the slider's movement distance, making it easy to exceed the electric actuator's range of motion when a long distance needs to be moved, thus preventing the lifting operation from proceeding properly. Furthermore, excessive weight of the goods increases the working pressure on the electric actuator, potentially damaging it. Utility Model Content
