There are always machines with huge bodies in such high-rise buildings. There is a kind of machine that can be placed on other cars. It has a particularly long straight arm, and there is also a small room that is very common in people's lives. There is a scientific name called a truck crane . The truck crane refers to a crane that is mounted on a special automobile chassis or a general automobile, and has an independent lifting operation room and a car cab. We can often see it at the construction site and road construction, and usually we will stay away from it because we have a kind of inherent fear of this kind of iron “monsterâ€, for fear that one can walk through it. There will be accidents and the like in an instant. One of the greatest advantages of a truck crane is its fluidity and its ease of handling. However, there are also bad places. It is that it cannot work on muddy roads. It has a higher demand on the road surface. It can be said that working on loose land will greatly reduce its use. Work efficiency is even difficult to move. The work of the truck crane was done according to the principle of the pulley lever. At the time of studying junior high school physics, we had contact, and we also learned a little about the application of the pulley in life. Here, I will give you a brief introduction. Such a big thing is how to handle it freely, and it has also become a good helper for human development. In the lower part of the truck crane there is a reel, which is specially used to wind the wire rope assembled on the pulley. Even though the wire rope is not particularly thick, there is enough tension to ensure the smooth running of the work. The telescopic arm is made up of several sections, so the wire rope will be sent to the upper arm through the pulley on the rear arm section. After a section of one operation, the reel will start to roll the wire rope, just like before. People use pulleys to pull water in a well, and the telescopic arm slowly descends. Let's talk about its control room, a completely independent space, a wide field of vision, 360-degree views without dead ends, and precise operation. Although the car crane is large and has a large power, there is no much noise when it is available. This is still very rare.
