The construction unit shall review the foundation bearing capacity of the tower crane foundation according to the requirements of the tower crane manual and the geological conditions of the installation site before the tower crane is installed to ensure the safety of the tower crane installation and use.

The bearing capacity of foundation in different areas is very different. Therefore, we must review the bearing capacity of foundation under the concrete foundation of tower crane.

When the carrying capacity of foundation does not meet the strength requirements stipulated in the manual, corresponding technical measures such as supplementary pile foundation should be taken to make up for it.
The fixed tower crane of the cross beam foundation can also use a split reinforced concrete foundation. The four corners of the cross beam base of the tower crane are installed on the basis of four reinforced concrete.

The size of concrete should be determined by the strength of the foundation under the concrete foundation. Different types of Tower hoists shall determine the side length and height of concrete foundation according to the requirements of the tower hoist usage instructions.

Reinforced bars and reinforcing bars in partitioned concrete foundations must be executed using instructions. If there are special requirements, the construction unit should carry out the strength design and provide specific technical documents to implement the construction.
With heavy science and technology as the background, the high-level corporate culture is integrated into the lives of employees. The ink depicts the people-oriented management concept and the backbone of the real gold forging crane industry.

Look at the same and different points of various models from the top structure of the tower crane
Tower hanging has been developed in China so far. There are nearly a thousand companies that produce tower hanging and tower hanging accessories.

Various tower hanging models emerge one after another, and the uses are very different. One of the important distinguishing criteria is the top structure of Tower hanging. The top structure of the tower crane mainly refers to the structure combination of the boom, tower cap and balance arm.

1. cantilever structure(flat head tower crane)
Stress: The lifting arm and the balancing arm of the flat head tower crane belong to the static structure of the cantilever. The mechanical model is single and the calculation is simple. The internal force is larger under the same load.
Amount of steel structure: because of the cantilever force, it is compared with other structural forms.

Manufacturing: No tower cap, pull rod and other structure manufacturing simple.
Installation and disassembly: low installation height requirements, reduce the requirements for lifting equipment during installation and disassembly, save the cost and time for disassembly, and facilitate aerial disassembly;

Suitable for cross operation of cluster towers; It is suitable for situations where there are special requirements for height.
2. fixed tower cap, static external extension structure balance arm, single suspension point static structure boom structure
Force: more complex than the flat head tower hanging, more simple than double hanging points.
Amount of steel structure: materials in Pingtou Province; But it's more than a double hang.
Manufacturing: Fixed tower cap manufacturing complex; The balance arm is simple for the planar structure;
Installation and disassembly: high installation height required; Installation and disassembly are more complex than flat heads.
3. fixed tower cap, static extension structure balance arm, double suspension point one Super static crane structure
Stress: The load of the lifting arm for a super-static structure is more complex than that of a single suspension point.
Use of steel structure: For a super-static structure, the most economical material.
Manufacturing: Fixed tower cap manufacturing complex; The balance arm is simple to make for a planar structure.
4. piece tower cap, static cantilever structure balance arm, single suspension static structure boom structure
Stress: The stress analysis of the flat head tower is more complicated, but it is still a static structure.

The lifting arm lever, balancing arm lever and sheet tower cap are added, and the lifting arm and balancing arm force are changed.
Amount of steel structure: static structure than Pingtou provincial materials; But it's more than a double hang.
Manufacturing: the sheet tower cap structure is simpler than the fixed tower cap, and the balance arm is more complex than the fixed balance arm.
Installation and disassembly high installation height required; Installation and disassembly are more complex than flat heads.
5, piece tower cap, static cantilever structure balance arm, double suspension point one Super static cantilever structure
Stress: The load of the lifting arm for a super-static structure is more complex than that of a single suspension point.
Use of steel structure: the crane is a super-static structure, the most economical material.
Manufacturing: the sheet tower cap structure is simpler than the fixed tower cap, and the balance arm is more complex than the fixed balance arm.

The double suspension structure requires high machining precision of two pull rods.
Installation and disassembly: high installation height required; Installation and disassembly are more complex than flat heads

On the Advanced of the Design Concept of Standard Festival of Tower Hang
The part of the tower tower body consists of the height of the base frame, Foundation section, reinforcement section, standard section, and half section. In the tower crane accessories, the tower crane standard section is the main force component and is also an important part of the lifting tower.
The combination design refers to the grouping of series products. Different products or the same product structure in the group can achieve a certain degree of interchange combination to form a new tower crane, thus greatly saving resources and improving the installation efficiency of the tower crane.

This combination design concept is particularly prominent in the tower crane standard festival.
As we all know, the standard section of the tower crane is the most interchangeable combination.

The advantage of standard section swaps is that they can first reduce material idleness. For example, when the small tower standard section has insufficient reserves, the idle large tower standard section is used.

Secondly, the large tower standard festival is used as the base section of the small tower to increase the independent height of the small tower and can also meet the needs of special projects.

For example, the standard section of TC 7040 can be used as the standard section of TC7030. The independent height of 7030 can be increased from the original 48 meters to 66 meters.
