Cranes stand out on any construction site due to their height and weight. Thanks to them, the process of building a building is gaining momentum, because they are helpful in the performance of many works. Such equipment can be divided according to type, structure or parameters. Two types of cranes are most often distinguished: tower cranes and self-propelled or stationary and mobile cranes.
What are tower cranes used for?
Today, cranes are used on every construction site, because more and more often their smaller types can be found, which are helpful in erecting a single-family house. Their downside is stationary work. Each change of the workplace causes the disassembly of the equipment and its reassembly in the next one. Incomplete work planning and crane handling is time-consuming and generates high costs.
On the other hand, this equipment has a large operating range. Its use does not require the creation of technological roads, which translates into lower operating costs.
Application of mobile cranes
This type of equipment travels on roads and construction sites. It is used in places where it becomes necessary to change the position of the crane. It is mobility that is the most important feature of such cranes. Their use does not generate the costs of assembling and disassembling the equipment. There are different types and sizes of devices. For this reason, you can choose the right equipment for the needs of a given site.
Unfortunately, this type of crane has a shorter working range than a tower crane. Yes, there are devices with a long range, but in this case the costs will be generated by the amount of equipment rent. The price per man-hour is also higher. To safely move a wheeled crane, it will be necessary to create a technological road.
The remaining breakdown
In addition to the above-mentioned, the most popular division of cranes, these devices can be classified according to the place of rotation, type of boom or method of assembly.
Division according to the place of trading:
- upper-turn – rotation of the boom with the cabin,
- low-speed – rotation of the entire structure,
Division according to the type of boom:
- tilting boom,
- leading boom – there are two types: extraction and no-tension,
Division according to the method of assembly:
- mounted using an auxiliary crane – much slower and requires additional equipment.
Choosing the right crane will determine the progress of construction work. When selecting, it is important to take into account the conditions on the site and the parameters of the machines. In addition, this equipment has a significant impact on the safety of employees.
