Full Technical Description

865 647 89 LINK, CHAIN As a key component in the boom's mechanical linkage, this part transfers force from a hydraulic cylinder to another section of the boom. It ensures that the geometry of the positioning system is maintained, allowing the operator to aim the drill feed accurately. Its specific length and strength are essential for the entire system to function as designed.

A worn or damaged CONNECTING LINK directly affects both safety and performance. Excessive wear in its pivot points creates play in the boom, which makes precise hole collaring difficult and can introduce shock loads into the structure. In a worst-case scenario, a complete failure of the link could cause the boom to move unexpectedly, creating a significant safety risk.

During routine walk-arounds, visually inspect the link for any signs of cracking or deformation, particularly near the pin bores. If you notice the boom feels loose or makes clunking sounds during movement, this component and its associated pins should be checked for wear. Proper greasing of the pivot points is the best way to extend its service life.
