Abstract: Based on the more and more extensive application range of electric chain hoist and the more and more diversified working conditions, this paper briefly introduces an application of 35t large-tonnage electric chain hoist-lifting in and out of the well during tunnel excavation of shield machine . Through the brief introduction of this article, it is believed that the application of electric chain hoists will become more and more common in more similar working conditions.
Due to its advantages of large capacity, fast speed and punctuality, the subway has become an important mode of transportation for most citizens. As an important means of transportation in the city today, the subway has a pivotal impact on raising the value of the area along the line, surrounding residents' travel, and even choosing a place to live. More and more people take the subway as an important consideration when choosing a place to live. Therefore, the subway has an impact on urban development and real estate values. In subway construction, there are usually two modes of laying routes underground and on the ground, and the most common one is the underground mode. In subway construction, tunnel excavation is a very large project, and generally involves a lot of hoisting machinery and equipment, such as gantry cranes and truck cranes. The shield lifting of the mechanism requires the use of electric chain hoists. This article briefly introduces the application of 35t electric chain hoists in tunnels.
In the process of tunnel excavation, it is necessary to use a shield machine for excavation. The customer needs to go down or lift the shield part of the shield machine. The space is small, the tonnage is large, the precision is high, and the lifting speed is slow. Through the analysis of the on-site situation in the early stage and the actual surveying and mapping of the actual construction site, we recommend a 35t electric chain hoist, which can be used in conjunction with the on-site truck crane to achieve tasks such as shield tunneling.
In the application of the 35t electric chain hoist in this subway project, it can realize the lifting and lowering of large heavy objects in a narrow space, with stable speed and high precision. Through remote control, remote control can be realized, which is convenient and reliable. Used in conjunction with large truck cranes, it can complete the lifting and lowering of the shield body of the shield machine. Therefore, this solution provides a good application case for other related tunnel construction projects. It is hoped that more and more applications can be seen in the construction of other related projects to provide a more reliable lifting solution for the industry.
