Function of Excavator Bucket H-Link & I-Link (Bucket Linkage)

Below is plain English explanation for overseas buyers, suitable for product description:

Core Function

H-links and I-links are key connecting parts of the excavator bucket linkage system. They work with the bucket cylinder, arm and boom to transmit hydraulic power.

Detailed Working Principle

Power transmission
They connect the bucket cylinder to the bucket. When the hydraulic cylinder extends or retracts, the links pull/push the bucket to perform digging, scooping, lifting and dumping materials.
Force distribution & load bearing
These links bear heavy impact and load during excavation. They share stress to protect the bucket, arm and hydraulic cylinder from damage.
Stable movement
They keep the bucket moving in a fixed track, ensuring flexible and steady rotation of the bucket during operation.

Simple Summary for product page

Bucket H-link and I-link are critical linkage components. They connect the bucket cylinder and bucket, transfer hydraulic force to realize bucket digging and dumping actions, while supporting heavy working loads and stabilizing bucket movement.
