Dig It or Miss It? The Ultimate Excavator & Heavy Engineering Masterclass

What is the primary purpose of the H-Link in an excavator front-end linkage?

Correct!

Incorrect!

The H-link, working in tandem with the bucket link (I-link), forms the four-bar linkage mechanism. It translates the linear retraction and extension of the bucket cylinder into the smooth rotational movement of the bucket, optimizing digging force.
