Functional Importance in Drilling Systems

In Atlas Copco rock drilling equipment, the 3216 8781 00 LINK ATLAS COPCO functions as a stabilizing and movement-enabling part. Its dual-hole design allows for a direct yet flexible mechanical connection between parts such as the feed beam, hydraulic cylinder mounts, and pivoting sub-assemblies. By offering a rigid axis for motion transfer, this link ensures balanced movement and force distribution throughout the machine.

Key Benefits:

• Precision Fit: Maintains optimal spacing and geometry between critical drilling components.

• Load Absorption: Helps mitigate shock and lateral force loads during percussive action.

• Assembly Integrity: Prevents component drift or loosening under vibration-heavy operations.

• Maintenance Efficiency: Easy to remove and replace without the need for disassembling surrounding parts.

• Extended Lifespan: Manufactured from impact-resistant alloy steel to ensure minimal wear over thousands of drilling cycles.

Applications Across Atlas Copco Drilling Models

The 3216 8781 00 LINK ATLAS COPCO is compatible with a variety of Atlas Copco rock drill models used in surface and underground operations. This includes equipment designed for applications such as mining, quarrying, foundation drilling, and tunneling.

Compatible Atlas Copco Models Include:

• Atlas Copco ROC F7

• Atlas Copco ROC D7

• Atlas Copco ROC L8

• Atlas Copco PowerROC T35

• Atlas Copco FlexiROC D50 series

• Other compatible drilling rigs within the ROC and FlexiROC product families

Each of these models benefits from the link’s function as a stabilizing joint that upholds structural cohesion and drilling accuracy. Whether supporting the motion of a feed beam or serving as a connection point for hydraulic arms, this part ensures consistent mechanical behavior over repeated use.

Material Composition and Quality Control

The 3216 8781 00 LINK ATLAS COPCO is forged from high-grade carbon steel alloys, then subjected to advanced heat treatment processes to improve tensile strength and fatigue resistance. The dual-hole alignment is drilled and machined with tight tolerances to avoid slippage or misfit during operation.

To meet international durability standards, 3GEN Export ensures that each part is:

• Ultrasonically Tested for internal defects

• Surface Hardened to improve wear resistance

• Precisely Calibrated to allow smooth interaction with matching pins or brackets

• Non-Coated or Surface Blackened for rugged industrial application

• Corrosion-Protected against chemical and environmental exposure

These quality measures enhance the reliability of the link and reduce the risk of premature wear, cracks, or distortion under repeated mechanical stress.

Installation and Maintenance Guide

Installing the 3216 8781 00 LINK ATLAS COPCO is straightforward for any trained technician. Its symmetrical design and fixed-pin interface enable quick assembly into the drilling system using the existing hardware.

Installation Tips:

• Ensure both holes are aligned perfectly with mounting pins or bolts

• Apply a suitable anti-seize compound to prevent corrosion around fasteners

• Inspect the link surface for any deformation before reuse

• Replace worn or ovalized pins to prevent long-term misalignment

Maintenance Needs:

This component is considered low-maintenance due to its passive mechanical nature. However, routine visual inspection is recommended during scheduled equipment servicing to check for cracks, deformation, or elongation at the boreholes.
