Description

Technical Field

[0001] The utility model relates to the technical field of mobile cranes, in particular to a mobile lifting matching device. Background Art

[0002] Mobile cranes, as an efficient and versatile lifting and handling equipment, are widely used in port operations, workshop production, power engineering, construction sites and other fields. Although lifting machinery has a variety of names, cranes, as a general term for this type of equipment, are still deeply rooted in the hearts of the people. In particular, truck cranes, crawler cranes and tire cranes have become the leaders in the crane family due to their unique mobility and lifting capabilities. Cranes have a wide range of uses. They can complete various lifting tasks efficiently and safely. In factory workshops, cranes can easily lift heavy equipment and help the smooth operation of production lines; in ports, cranes are essential for cargo loading and unloading. It is a powerful assistant, greatly improving the efficiency of cargo transportation; in the field of power engineering, cranes can assist in the installation and maintenance of tall power facilities; and at construction sites, cranes are indispensable lifting machinery, providing great convenience for the vertical transportation of building materials. In addition, cranes also play an important role in emergency rescue. At the scene of natural disasters or accidents, cranes can quickly arrive at the scene and carry out emergency rescue work through their powerful lifting capabilities, winning precious time for saving lives and property. In short, cranes have become an indispensable and important equipment in modern industrial production and emergency rescue with their excellent performance and wide range of uses.

[0003] Mobile cranes, as a type of equipment that relies on wire ropes to connect hooks for lifting operations, often face some challenges during operation. First of all, due to the flexibility and dynamic characteristics of the wire rope, the hook of the mobile crane is prone to shaking during the lifting process. This shaking will not only cause the lifted cargo to swing unstably, but also increase the risk of cargo unhooking, thereby greatly reducing the practicality and work efficiency of the mobile crane. What is more serious is that when the wire rope of the mobile crane breaks due to long-term use or improper operation, the consequences will be disastrous. In this case, the hook and the cargo will lose support and fall directly to the ground. This sudden fall may not only cause serious damage to the cargo itself, but also threaten the surrounding environment and personnel safety, bringing immeasurable losses. Therefore, in order to ensure the safety and stability of the mobile crane, the operator must receive professional training, strictly abide by the operating procedures, and regularly maintain and inspect the equipment. Only in this way can we give full play to the effectiveness of the mobile crane and ensure the safety of the work site.
