Tower cranes are used in the transportation industry for loading and unloading, in the construction industry for moving materials and materials, and in the production industry for the purpose of assembling production equipment. New tower cranes have become famous for their many capabilities in carrying objects of different weights in vertical and horizontal directions. A tower crane uses a suspended cable and a driving arm to move objects. Tower cranes have different capacities for carrying materials, but the normal capacity is between 8 and 16 tons. Tower cranes are generally classified into three categories:
🔸 fixed tower crane
🔸 mobile tower crane
🔸 rising tower crane
Fixed tower crane is used for normal construction, this type of tower crane cannot be moved or increased in height.
Mobile tower crane is more advanced and has more capabilities than fixed tower crane. be This type of tower is equipped with a hydraulic telescopic boom connected to the platform and has more equipment for operation.
The climbing tower crane increases the height with the increase in the height of the building, and its special advantage is the wide coverage of the z axis of this type. Tower crane is used in bridge, tower and skyscraper industries.
🔶 Types of tower crane in terms of installation type 🔶
Self-installing tower crane (self-tensioning)
The self-installing tower crane has a high installation speed and load carrying capacity compared to other models. The self-installing tower crane receives its driving and installation power from the generator and the engine that is built into it, and it has a lot of power in operation. It is external and uses electricity and has large dimensions. They are used to move objects at high altitudes. The tower crane that is installed does not have the ability to automatically move the cargo, and it is handled by a special carrier system. This type of tower crane has two models:
🔸 Tower crane with the help of installing the cross
🔸 Tower crane with the help of installing dry canvas or r
series of cross-mounted tower crane is in the shape of a cross, and this form causes movement in different and desired radii, and this design helps to move the load in high tonnage.
Dry canvas tower crane or r model is in the shape of English letter r, which is known as R series or MR series. There is no Chariot tower crane in this model and the radius of movement of its arm is up and down.
