Mast Section: The "Body" Of A Tower Crane

What are its core functions and roles?

1. Constitutes the main body of the tower, providing structural height.

2. Transmits and bears all loads.

3. Ensures overall stability and rigidity.

4. Serves as the attachment point for the climbing system.

Why is it called a Mast section?

Mast sections of the same model of tower crane have strictly standardized dimensions and interfaces, ensuring that mast sections of multiple tower cranes can be interchanged in the same project, improving equipment utilization and flexibility. This is why it is called a "mast section."

What types are there?

1. Integral Mast Section

2. Panel Mast Section (modular)

What are the advantages and disadvantages of each type?

1. Advantages:

Integral mast sections have high strength and are quick to install, making them the most mainstream type currently.

Panel mast sections require less space for transportation, suitable for situations with extremely limited road transport conditions.

2. Disadvantages: Panel mast sections (modular): Require more on-site installation work, and their overall rigidity is slightly inferior to that of integral sections.

Which aspects should be inspected and maintained regularly?

1. Structural inspection: Check for cracks, rust and plastic deformation in welds, steel pipes and Angle steels.

2. Connection inspection: Check if the bolts are loose, missing or rusted.

3. Anti-corrosion treatment: Regular anti-corrosion treatment should be carried out to prevent the steel structure from weakening the cross-sectional strength due to rust.

The tower crane mast section is the most core and fundamental component of the tower crane structure. It forms the "body" of the tower crane, directly determining its height, stability, and load-bearing capacity.
