I remember reading the geographer David Harvey who talked about the construction crane. This is a very beautiful cosmic object I think - I always look at the construction crane, and I have a super 8 lens for many construction cranes. I think they are a strange and magical element in my social circle. But he has a whole article on how to "read" construction cranes: if you have lots of construction cranes in your city, it is a city that invests a lot of global capital There may be. So now I see construction cranes, do not look at these skyful, strange, dinosaur-like things in the sky - I also see capitalism at work

There are various forms of cranes, each suitable for a particular application. The range of sizes range from the smallest cantilever crane used at workshops to the highest tower crane used to build high-rise buildings. A small crane is also used to build a skyscraper to promote the building by reaching a narrow space. Finally, you can find a large floating crane commonly used for construction of oil drilling equipment and shipwrecks for salvage saving. Cranes used to lift heavy loads were invented by ancient Greeks in the second half of the 6th century BC. Archeological record shows slower than c. In 515 BC, a unique cut of raised tongs and Lewis irons began to appear above the stones of the Greek temples.

Cranes are machines used to lift heavy objects and are often used to move heavy objects at construction sites. Since fixed cranes are less mobile than other types of cranes, they are heavier and can lift higher loads. The fixed crane is a tower crane. Tower crane is basically a modern balanced crane. Because tower crane combines lifting capacity and height, it usually provides the most useful function. Therefore, when building a skyscraper it is necessary to build a tower crane.
