Skeleton buckets with Hardox® round bars

Contact us

Description of the case

We supply buckets for excavators ranging from 1.5 to 75 tonnes. The majority of the skeleton or sieve buckets are equipped with Hardox® round steel bars. Compared to steel plates with a flame-cut sieve surface, these new round steel bars offer impressive benefits. Hardox® round steel bars are hard to the core and remain fully hardened even after the completed machining process. They are cut only to the length needed to manufacture the skeleton bucket. The heat input is minimized, leaving the steel’s hard and tough properties intact. Thanks to the shape of the round bars in the skeleton buckets, the material can roll on the bars. This reduces the abrasion effects on the bucket. Less material is getting stuck in skeleton buckets with round steel bars, improving the sorting efficiency. Depending on the customer’s requirements and intended application, the round steel bars can be welded to the bucket or even integrated with turned Hardox® round bars into the frame. This ensures the highest level of wear resistance to the entire bucket construction, even in heavy-duty applications.
