H Links and I Link for Excavator
“What’s the difference between all the different links - H Links, Bucket Links, Side Links and Tipping Links?”
Bucket Links are also known as H Links or H Brackets due to their shape.
This is the main link that connects the lower boom ram to the bucket (or quick hitch). It is this main link that moves the bucket in and out as the hydraulic lower boom ram extended and contracts.
Tipping Links are also known as Side Links, or even Banana Links due to their shape!
These act as pivot arms to move the digging bucket. The links are situated either side of the arm and are attached on the one end on the lower boom arm and the other end is attached to the lower boom hydraulic ram.
Here at GT, we offer a vast range of Bucket links, H-links, H-brackets, Side Links and Tipping Links for the most common excavator models from manufacturers including Kubota, Takeuchi and JCB.

H-Links
Also known as bucket links or h-brackets due to their shape, these guys are the main connection of the lower boom cylinder and the bucket or quick coupler. They are responsible for moving the bucket/ attachment when the bucket cylinder extends or contracts.
Side Links
Also known as tipping links, or banana links due to their shape, these links are pivot arms responsible for moving the digging bucket. They are found on either side of the stick and are attached to both the lower bucket cylinder and the bottom of the stick as a connection point. Without these links, the bucket cylinder would not be able to provide the power needed to move the bucket in and out effectively.
