The tower crane is 400 meters above the ground. How did the tower crane master climb up to work?

Tower crane is an indispensable tool in building construction. If there is no tower crane, the house can't be built forever. We all know that tower cranes are basically used in construction sites now, and tower cranes give us the feeling that they are tall and dangerous. At the same time, we will also worry about the safety of the tower crane master. After all, the tower crane master works in the air from tens to hundreds of meters. Here, I also want to praise the hard-working tower crane masters. Thank you for your contribution to infrastructure construction in China. Perhaps for us ordinary people, seeing the tower crane working at an altitude of 400 meters will lead to a question, that is, how did the tower crane master climb up and work at such a high altitude?

Many people may wonder, can tower cranes automatically expand and contract like fire stairs? In fact, the tower crane can be built so high, and it is also assembled section by section before it really rises. Insert the standard section into the reserved area below the cab, and the tower crane can continue to rise until it reaches the working height. But first of all, a solid foundation must be established at the bottom of the tower crane. The more solid the foundation, the higher the safety of the tower crane will be. When the foundation tower crane is built, the hydraulic device above the tower crane can automatically rise and fall without the assistance of other equipment.

Of course, the rising height of tower crane is limited. For those high-rise buildings with hundreds of meters, tower cranes are attached to the roof and then work. First, the foundation tower crane is built on the roof, and then the tower crane rises and falls by itself, which can not only save costs, but also ensure the construction safety. Although the tower crane works hundreds of meters in the air, it is not high in height and has a solid foundation because it is attached to the roof. If the tower crane is allowed to rise to 400 meters by itself,

As for how a tower crane master climbs to work on the tower crane, there are actually two main ways. One way is to climb directly to the cab through the stairs inside the tower crane, which is suitable for lower tower cranes. The second way is to take the construction elevator to the construction floor, and then climb to the cab through the stairs inside the tower crane, which can also save the tower crane master a lot of time. If the tower crane itself is several hundred meters high, it will take a lot of time and be dangerous just to climb the tower crane. For example, in the construction of Shanghai Tower, the structural height of the whole building is 580 meters. It is impossible to build a tower crane 580 meters high for operation, but it is built on the top floor of the building, so the tower crane master actually only needs to climb more than ten meters to the cab.

Finally, the headmaster concluded that the tower crane is an indispensable equipment in the construction, and the tower crane driver is also a very dangerous and hard work. When working at an altitude of 400 meters, drivers usually take the construction elevator to the corresponding floor first, and then climb the tower crane. After reading it, I finally understood.
