I’m sure everyone has seen tower cranes before. They are generally used in building construction, and their height can range from several dozen meters to even over a hundred meters. I wonder if any of you have ever had the same question as me: how do tower cranes rise to such heights? At first, I thought that these cranes were assembled piece by piece by manual labor, but after watching the explanations provided by the creator Era Intelligent Manufacturing Plus on Xigua Video, I realized it’s not as simple as I thought. Just as its name suggests, Era Intelligent Manufacturing Plus creates many short educational videos on Xigua Video; those who are interested can give them a look. Now let’s take a look at how tower cranes actually rise to such heights. In fact, a tower crane is composed of several standard structural units, each of which can be separated. It isn’t assembled manually as I initially thought. In addition, the tower crane is equipped with a climbing frame used for lifting workers up and down the crane. This frame serves primarily to transport workers, and it is also a key component in lifting the crane. As can be seen from the images, the cross-section of this climbing frame is C-shaped. Whenever the crane needs to be raised, the climbing frame is first lifted to the junction point; then the crane lifts a standard structural unit and places it on the open side of the climbing frame. The hydraulic rods at the bottom of the climbing frame then lift the crane upward until it reaches a height where another standard unit can be placed. After that, another standard unit is lifted and pushed into the open side of the climbing frame, after which the newly added unit is connected to the crane itself. This process is repeated continuously, allowing the crane to be raised gradually. After watching the explanation of Time Intelligence Manufacturing Plus on Xigua Video, I would like to share my own views. The risks associated with working at great heights are indeed extremely high; workers who operate tower cranes spend entire days on those cranes, carrying out all their daily activities there, which is no easy task at all. However, everything has two sides – although it’s dangerous, their earnings are much higher than those of ordinary workers. Here, I also hope that all workers who operate tower cranes will pay attention to safety while at work. Speaking of tower cranes, I’m actually very curious about them as well. Besides how they rise, I wonder if they descend in the same manner. After watching the explanations provided by Time Manufacturing Plus on Xigua Video, some viewers might ask whether a tower crane could collapse if its standard sections are not aligned during lifting and lowering. If that’s your question, you can download the Xigua Video app and search for Time Manufacturing Plus; their videos contain many informative explanations on this topic. That’s all for this episode; see you next time. Source: Leng Shen Talks About Knowledge
