Because tower cranes are fixed on the construction site, they can handle the toughest jobs. The tower crane is used to lift and transfer the heaviest equipment, and even for simple maneuverability, it can be equipped on the side of the structure. The need to use height was the most important reason for the invention of tower cranes. These structures are used efficiently and effectively in all kinds of construction projects.
Tower cranes are divided into different categories, each of which has its own characteristics and applications. Different types of tower cranes include the following: 1. Static Tower Crane: This type of tower crane is connected to the ground and is usually used in long-term and large projects. - It has the ability to rotate 360 degrees and is very suitable for loading at heights. 2. Mobile Tower Crane:
- This type of tower crane can be moved and can be easily moved from one place to another.
- It is usually used in smaller and temporary projects.
3. Luffing Tower Crane:
- This type of tower crane has a variable arm that can move up and down.
- Suitable for projects that are located near other buildings. , because it can move loads to different places without moving.
- This type of tower crane has a horizontal arm and is usually used in large and high-rise projects. Accessed many times.
5. Hammerhead Tower Crane:
- This type of tower crane has a horizontal arm that is designed in the shape of a "hammer".
- It is usually used in large and industrial projects and has the ability to load It is heavy.
6. Climbing Tower Crane: This type of tower crane rises vertically and can increase with the height of the building. It is usually used in high-rise projects and multi-story buildings.
Each of these types of tower cranes are selected depending on the needs of the project and environmental conditions.
What is the method of increasing the height of Crane Tower?
One of the most common questions that are often asked is how to install tower cranes. The tower crane is built piece by piece like a puzzle. The various components are delivered to the project site by transport trucks and assembled using mobile cranes. First, the base is concreted, then the tower is built.
The method of increasing the height is that in the lower part of the chamber, a part of the main column is made of two layers. When there is a need to increase the height, one of the layers that is connected to the upper part is pulled up using the existing jacks to prepare an empty area between the chamber and the main column. At this stage, the experts with Installing the extension part connects the horizontal part to the new part and the lower layer to the mast structure, in this case we will see an increase of several meters. Then the rotary table and the cabin are put in place. At the end, the pocket and braces are placed in place along with the counterweights.
