A headed pin is a specialized fastener used in tower cranes to connect structural units. It consists of a cylindrical metal rod with a flattened head, designed to prevent rotation or sliding of connected parts. The pin is inserted through aligned holes, and a securing mechanism is used to keep it in place, ensuring the crane's stability. The pin's design and material are carefully chosen for strength and durability, ensuring the safety of the crane structure.

Crane Pin description

A headed pin is a specialized fastener used in tower cranes to connect structural units. It consists of a cylindrical metal rod with a flattened head, designed to prevent rotation or sliding of connected parts. The pin is inserted through aligned holes, and a securing mechanism is used to keep it in place, ensuring the crane's stability. The pin's design and material are carefully chosen for strength and durability, ensuring the safety of the crane structure.The crane pin also possesses following characteristics:

1) The headed pin used in tower cranes is exposed to harsh outdoor environments, enduring prolonged exposure to sunlight and rain. It requires sufficient corrosion resistance, withstanding a minimum of 240 hours of salt spray testing.

2) The headed pin needs to possess adequate mechanical properties. Generally, materials such as 35CrMo or 42CrMo are chosen, ensuring their tensile strength, yield strength, and elongation meet the optimal performance requirements.

3) Considering that the headed pin needs to be installed during tower assembly and removed after completion of the project, it is essential to ensure sufficient surface lubrication to reduce friction and prevent damage.
