Product Description
Lock pin E-17278-10
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
Integral Head Design: Precision-forged head provides positive mechanical stop during installation, preventing over-insertion and ensuring correct assembly positioning.
Premium Material Composition: Constructed from high-grade alloy steel with optimized chemical composition for superior strength-to-weight ratio.
Comprehensive Heat Treatment: Through-hardened and tempered to achieve consistent mechanical properties throughout the shaft cross-section.
Precision Ground Bearing Surfaces: Critical contact areas finish-ground to micron-level tolerances for minimal friction and extended bushing life.
Advanced Corrosion Protection: Multi-stage coating system provides exceptional resistance to moisture, chemicals, and UV exposure in outdoor environments.
Applications
Tower Crane Main Structures: Primary connection point for mast section joining, tie-in frames, and tower head attachments.
Slewing Platform Connections: Secures upper rotating structure to lower mast sections, transmitting full operational loads.
