Abstract
Description
Technical Field
[0001] This utility model relates to the field of tower crane construction technology, and in particular to a method for leveling the pre-embedded foundation section of a tower crane. Background Technology
[0002] In recent years, with the high-quality development of the construction industry, large tower cranes have become increasingly widely used due to their advantages of large lifting capacity and high safety factor. Under this premise, the pre-embedded foundation sections of large tower cranes have also become increasingly common. However, during the construction of these pre-embedded foundation sections, the large weight of the sections makes leveling difficult, often resulting in the levelness of the pre-embedded foundation sections exceeding standard requirements. This leads to overall verticality issues after installation, posing serious safety hazards to the entire system's installation, use, and dismantling. To address this issue, a leveling device for pre-embedded foundation sections of tower cranes has been specifically developed. This device can easily and quickly adjust the levelness of pre-embedded foundation sections of various tower crane models, reducing the workload of workers, ensuring the construction quality of the pre-embedded foundation sections, and eliminating the safety hazards caused by excessive levelness of the pre-embedded foundation sections.
