Modern construction involves the comprehensive use of a wide range of special machinery and equipment. This list here includes construction tower cranes related to slewing technology with a functional boom. It is located in the upper structural part of the provided tower. These cranes carry out the lifting and the necessary transfer of certain heavy loads over a long distance and height. The boom and the slewing mechanism do the best for this.
Factors of the irreplaceability of technology
This technique is rightly considered indispensable. This is due to the following significant factors:
- the ability to differentiate boom reach and lifting height;
- the ability to move short distances;
- unfold within the construction site.
It should be noted that all tower crane actuators are equipped with special locking devices. The configuration of these nodes is only available in specialized organizations and cannot be changed by the crane operator.
According to statistics, the share of tower cranes in the total machine park of construction equipment today is at least 18 percent.
Classification of heavy-duty equipment by purpose
Based on the specific place of installation of tower cranes, the following classification was adopted:
- general purpose equipment . Widely used for both industrial and residential construction;
- special devices . These cranes are used for certain types of industrial construction;
- loading cranes . The technique is used in huge landfills, bases and warehouses.
What are the elements of a crane?
Modern construction tower cranes include the following structural elements:
- tower structure;
- functional boom;
- operator's (driver's) cab for control;
- common support;
- rotary-axis device.
To perform basic functions, any kind of such equipment is equipped with:
- blocks;
- winches;
- other additional mechanisms.
Modern crane towers can have both lattice and telescopic structures. It is noteworthy that it can be increased if required by the technology of construction processes.
