From the afternoon of July 26th, heavy rainfalls in South Korea's Seoul, Gyeonggi, Gangwon, Busan, and Gyeongnam districts dropped for more than a century, causing many mudslides, traffic jams, blackouts, flooding of streets and residential areas. South Korean relief agencies stated that as of 11 pm local time on the 27th, at least 36 people were killed and dozens of people were still missing. In the early morning of July 27, Chuncheon, a mountain resort in the eastern part of Seoul in the South Korean capital, caused mudslides due to heavy rainfall. At least 9 people were killed, 2 people were unaccounted for, 20 were injured, and 4 buildings were razed to the ground. From the perspective of the photographs, the construction machinery can be seen everywhere. In the face of huge natural disasters, especially when disasters such as earthquakes and floods came, the importance of construction machinery was fully reflected.

In recent years, there have been frequent natural disasters around the world. Snow disasters, earthquakes, mudslides, floods, etc... In the face of frequent natural disasters, construction machinery has become one of the most urgently needed rescue equipment for people to save lives. According to a senior analyst from China Construction Machinery Business Network, the main application fields of construction machinery are after the original seven fields, and one more field has been added – to resist natural disasters. Disaster relief, construction machinery is incumbent! Excavators, bulldozers, loaders, cranes, forklifts, generators, transport vehicles, trailers, high-altitude fire fighting equipment and other large-scale engineering machinery and equipment have become the backbone of the disaster area rescue.

In 2008, the snow disaster in the south made the Chinese people intuitively aware of the disaster relief effect of construction machinery for the first time. To combat natural disasters, the role of construction machinery has been fully understood. However, almost all construction machinery products do not have the ability to adjust their own equipment performance or attachments to a specific working condition, but rely on conventional operating modes to complete disaster relief tasks. If the equipment can be adapted to the disaster relief environment by replacing the equipment, its working efficiency will be higher.

Faced with the complexity of natural disasters, how to cope with natural disasters, and post-disaster reconstruction, in addition to high expectations for manpower, people seem to have higher requirements for construction machinery. At present, cranes, bulldozers, excavators and other products have been able to fully perform various disaster relief tasks at disaster sites. However, there is no one machine that can quickly and safely clear or open up new roads to create conditions for the construction machinery and all kinds of materials to enter the disaster area. Apart from the efficacy of the product, for the enterprise, this is an important manifestation of its social responsibility. For enterprises that are capable of participating in disaster relief and reconstruction, it is even more important to study how engineering machinery products respond to the special circumstances of natural disasters. At present, the national emergency equipment is moving toward standardization and institutionalization, and various rescue measures are continuously improving. China's construction machinery companies have stepped up their research, development, and production of emergency rescue equipment, manufactured rescue equipment that is more adaptable to the disaster scene, and implemented the most efficient rescue operations to save lives and property.
