[0002] Water conservancy construction refers to various engineering and technical activities carried out in the process of water resource development and utilization, aiming to achieve the effective management, protection and utilization of water resources, including water resource planning, reservoir construction, river regulation, irrigation and drainage, hydropower generation, flood control and drought relief, soil and water conservation and other aspects. The development of water conservancy construction technology is of great significance to improving the quality, efficiency and benefits of water conservancy projects, and is closely related to social development and the construction of ecological civilization. During the process of water conservancy construction, a lifting device is required to lift the materials used in the construction process to meet the construction requirements.
