An Important Parts Mast Section of Tower Cranes

The mast section of a tower crane is a crucial vertical structure that provides the main support for the crane. Here are some key points about it:

1. Composition: The mast section is typically made of steel and consists of multiple sections that can be assembled to reach the desired height. Each section is connected by bolts and hinges to ensure stability and strength.

2. Design: It includes components like the base pedestal, mast sleeve, and top plate. The base pedestal provides the foundation, the mast sleeve enhances rigidity, and the top plate ensures installation accuracy.

3. Function: The mast section is designed to withstand heavy loads and forces exerted by the crane during operation. It ensures the crane remains stable and safe, even under complex operating conditions.

4. Types: There are different types of mast sections, including self-supporting static, supported static, travelling, and climbing tower cranes. Each type has specific features and uses depending on the construction needs.

   
   

 For example L68B mast section is a critical component used in large jib tower cranes. Here are some key details about it:

1. Design and Structure: The L68B mast section is made up of four panels, two with telescoping lugs and two without. These panels are assembled using 20 special fishplate bolts, with the heads of the bolts positioned on the outside.

2. Materials: It is constructed from high-strength steel, ensuring durability and the ability to withstand heavy loads and harsh construction environments.

3. Dimensions: Typically, the L68B mast section measures 2 meters in length. Its modular design allows for easy assembly and disassembly, which is crucial for efficient crane setup and dismantling.

4. Load-Bearing Capacity: The L68B mast section is engineered to support substantial weights, enabling tower cranes to lift and maneuver heavy construction materials with ease.

5. Compatibility: This mast section is compatible with various models of tower cranes from manufacturers like Potain, Liebherr, and Zoomlion(TC6016A-8E、TC6015A-10E、TC6515B-12E、TC7013-10E、TC6520-10D、TC6520-10E、TC6513-6E、TC7525-16D、T6513-8E、T7020-10E)
