Manufactured from high-strength Q345B low-alloy steel, the tower crane mast section is a critical load-bearing structural component that supports the crane body, extends lifting height, and ensures overall equipment stability. Featuring a modular design, these sections offer reliable connections and easy installation, alongside excellent torsional rigidity, deformation resistance, and load-bearing capacity. Specifications include models such as 6015 and 7020, with cross-sectional dimensions of 1.6m×1.6m, 1.833m×1.833m, and 2.0m×2.0m; heights range from 2500mm to 3000mm, and individual section weights vary between 450kg and 650kg, supporting axial loads exceeding 800kN to 1000kN. The main structure is fabricated by welding high-strength square tubing (e.g., 135×135×14mm or 140×140×14mm) and angle steel, utilizing high-strength bolts, pins, or fishplate connections; welding processes comply with the automatic submerged arc welding requirements of the GB/T 12467 standard. Surfaces undergo sandblasting and anti-corrosion treatment (primer and topcoat), ensuring a service life of over five years. These sections are widely compatible with various tower crane models-such as QTZ125, TC6015, XGT7020, W7020, and HST7020-providing safe, stable, and reliable structural support for high-rise buildings, bridges, and large-scale infrastructure projects.
