HF (High Front) Elevator Bucket

Fabricated Steel

These continuous elevator buckets feature slow-speed, centrifugal discharge. Their three-piece, welded design is fully welded outside and partially welded inside. 

Why Steel?

Steel buckets should be substituted for nonmetallic buckets when the heat becomes too excessive or when the bucket elevator carries extremely sharp products.

Features

Has a high front for increased capacity and is designed for gentle handling of product.

Available in Stainless Steel and Carbon Steel.
