Component Specifications

Definition
The Connection Pin is a critical cylindrical fastening component designed for the Jib Foot Connection in industrial machinery. It serves as a mechanical interface that aligns and secures the jib foot to its mounting structure, facilitating precise load transfer and maintaining structural stability under operational stresses. Typically manufactured to tight tolerances, it prevents relative movement between connected parts while allowing for controlled articulation or disassembly when required.
Working Principle
The pin operates on the principle of shear and bearing resistance. It is inserted through aligned holes in the jib foot and its mating component, where it resists shear forces from operational loads (e.g., lifting, rotation) and prevents lateral displacement. Its cylindrical geometry ensures uniform stress distribution, while retention mechanisms (e.g., cotter pins, locking rings) secure it against unintended removal.
Materials
High-strength alloy steel (e.g., AISI 4140, EN19), heat-treated to achieve a hardness of 28-32 HRC for durability and wear resistance. Surface treatments may include zinc plating, black oxide coating, or phosphate coating for corrosion protection.
Technical Parameters
  • Length 100-300 mm
  • Diameter 20-50 mm
  • Tolerance h7/g6 fit
  • Shear Strength ≥400 MPa
  • Surface Finish Ra 1.6 μm
Standards
ISO 8734, DIN 6325, ISO 2338

Frequently Asked Questions

What is the primary function of a Connection Pin in a Jib Foot Connection?

It aligns and secures the jib foot to its base, transferring operational loads and preventing misalignment or detachment.

How often should Connection Pins be inspected?

Inspect during routine maintenance (e.g., every 500 operating hours) for wear, corrosion, or deformation, and replace if tolerances exceed specifications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
