HFO (High Front Overlapping) 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
Available in Stainless Steel and Carbon Steel.

■ Tapco recommends using gross x .75, for usable capacity
Style:
HFO (High Front Overlapping)
Design:
Slow speed centrifugal discharge.
Material:
Carbon Steel, Stainless Steel, Aluminum.
Method of Manufacture:
Fabricated.
Standard Construction:
The HFO 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”.
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 HFO 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.
