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.

Applications

Stone
Foundry Sand
Sand and Gravel

Style:

HF (High Front)

Design:

Slow Speed continuous discharge.

Material:

Carbon Steel, Stainless Steel, Aluminum

Method of Manufacture:

Fabricated

Standard Construction:

The HF style bucket utilizes a 2 piece design consisting of a pressed formed body and a front plate. All seams are continuously welded outside and partially inside. The bucket will be produced after Tapco supplies a CAD drawing to be approved by the customer.

Construction Options:

AR plate, wear lips, or hard bead welds

Material Thickness

14 ga., 12 ga., 10 ga., 7 ga. (3/16”), 1/4”, 5/16”, 3/8” and 1/2”

Standard Drilling:

No charge for standard belt or chain drillings

Venting:

Available on request. Contact Tapco for recommendations.

Usable Capacity:

Tapco recommends using 75% of gross, (100%) capacity

Spacing:

Contact Tapco for recommendations.

Interchangeability:

Can be intermixed with existing fabricated HF style buckets. If different weight buckets are mixed in, some care should be taken that the leg does not become too far out of balance. Check elevator for proper clearances. Contact Tapco for recommendations.

Installation:

On belt: Fanged elevator bolts and nylon insert lock nuts are recommended. Flat steel washers must be placed inside the bucket under the nuts.

On chain: Use Grade 5 hex head bolts with hex nuts, flat washers, and lock washers. Elevator bolts should not be used on chain attachments.

Caution:

Welding and cutting on elevator legs without taking proper precautions is extremely dangerous and can cause a violent explosion
