Product Description
Pin M-52278-19
Tower crane parts, black pin, material 35CrMo, surface treatment: Dacromet. Long pin with yellow zinc plating. High strength and corrosion resistance for tower crane.It is typically used to connect mast sections or to secure components like cross braces and spreaders, playing a vital role in the structural integrity of the crane.
Key Features
Robust Head Configuration: Integrated shoulder design ensures positive positioning during assembly and prevents axial displacement under dynamic loading conditions.
High-Strength Metallurgy: Constructed from premium alloy steel with comprehensive heat treatment to achieve optimal hardness, tensile strength, and shear resistance.
Advanced Surface Protection: Multi-layer corrosion-resistant coating provides exceptional durability in marine environments, extreme weather, and high-humidity conditions.
Precision Machined Bearing Surfaces: Critical contact areas are ground to tight tolerances for minimal friction, reduced wear, and extended service life of mating components.
Fatigue-Optimized Design: Engineered to withstand millions of load cycles without degradation, ensuring long-term reliability in continuous crane operations.
Applications
Tower Crane Superstructure: Primary connection point for crane mast sections, slewing rings, and tower head assemblies.
Jib and Counter-Jib Connections: Secures boom sections and counterweight support structures where reliable load transfer is essential.
Sheave and Pulley Systems: Functions as a stationary or rotating axle for wire rope guidance components under high line pull.
Heavy Rigging Applications: Suitable for critical lifting attachments, spreader bars, and custom lifting frames in heavy industrial projects.
