Hydraulic Breaker Presses Steel Strips on Excavator Bucket

Описание: A Little Wisdom Helps You Become Smarter !

In the video, a hydraulic breaker (commonly used for smashing rocks) is repurposed to press curved steel strips tightly against the curved backplate of an excavator bucket, while a welder stands by with a handheld shield, ready to secure the strips.

What’s happening?
This is a field repair technique to reinforce worn excavator buckets. The steel strips (often made of high-hardness materials like Hardox) are added to protect the bucket’s vulnerable areas from abrasion during digging or mining. The hydraulic breaker’s controlled impact force replaces manual hammering, bending the strips precisely to match the bucket’s curve. Once aligned, the strips are welded on-site for a permanent fix.

Why this method?

Efficiency: Hydraulic breakers deliver stronger, faster force than manual tools, ideal for bending thick steel in remote worksites.

Cost-saving: Rebuilding a bucket costs thousands; adding steel strips extends its life at a fraction of the price.

Adaptability: The technique works on uneven surfaces where machines like presses can’t be used.

Key details:

The steel strips are pre-cut but require on-site shaping.

Welding must follow strict protocols to avoid cracks from high-stress areas.

After welding, edges are often ground smooth to prevent snagging.
