Tower crane classification

By appointment distinguish:

• General purpose;
• Special cranes: for industrial construction
• Overhead cranes: self-elevating, creeping and attachment cranes
• Loader cranes: for warehouses, bases and landfills

According to the possibility of moving, they distinguish:

• Stationary - tower cranes fixed on a foundation or other fixed base.
• Mobile - able to move around the construction site without assistance.
• Self-elevating - they move along with construction progress.

By load capacity: - tower cranes of small lifting capacity - up to 5 tons - medium - up to 25 tons; - heavy-weight tower cranes - up to 100 tons and more.

Tower type:

• with fixed tower
• with swivel tower

Arrow type:

• with lifting boom;
• tower crane with beam boom.

Not only the amount spent on specialized equipment, but also the amount of costs for all construction work may depend on the correct choice of a tower crane. This is a rather complicated and time-consuming process that requires taking into account a large number of factors and technical parameters.

Tower crane selection criteria

Specifications of tower crane

Load capacity, lifting height and reach of the boom - these are the main parameters that you should pay attention to first of all when choosing the required model. In addition, one should take into account the indicators derived from the specified characteristics: load capacity at maximum boom reach, speed of lifting the load, the range and speed of movement of the cargo trolley, the height of attachment of equipment to the facility under construction, energy consumption. Another important factor is the ease of installation of the tower crane.

Design features

It is very important to consider the design of the boom. When choosing a tower crane, the design features of the driver's cab and boom should also be taken into account. The marketplace presents tower cranes for sale of various models and modifications, so there will be no problems with choosing the right equipment.

Object Height

When erecting high-rise buildings, special free-standing tower cranes or equipment on an anchor base with a device for self-extending the crane tower and the possibility of attaching it to the structure under construction are used. In such cases, top-slewing tower cranes are used.

If we consider the construction of low-rise buildings, then there is a different approach. Here you can use any tower cranes, but you should take into account the parameters of the object. In this case, hydraulic self-folding cranes are popular, the operation of which does not require high-altitude licenses. In addition, one person can operate such equipment.

Object type

At present, monolithic buildings are being built more and more often, which have practically replaced panel structures. Most construction companies in the construction of such structures use concrete pumps with hydraulic self-elevating distribution booms. This approach makes it possible not to use a tower crane for the delivery of concrete, which in turn allows you to choose equipment with an average load capacity.

In panel construction, the main criterion for choosing a tower crane is the mass of structures used. As a rule, we are talking about fairly large indicators, so equipment with a large carrying capacity is required. These are heavy tower cranes that are expensive and consume a lot of electricity. Therefore, in such cases, it will sometimes be wise to consider purchasing a used tower crane.

If you have any doubts when choosing a tower crane, be sure to contact the consultants. Otherwise, the use of unsuitable machinery can not only greatly affect construction costs, but also cause injury to workers.
