AA Elevator Bucket
Fabricated Steel
This versatile bucket comes in a wide range of materials to meet any needs you may have. They work especially well in high-throughput elevators that handle industrial-type materials. Whatever your elevator handles, there is a bucket to match it in the AA series.
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.

▲ The HD bucket has an extra heavy duty front lip for severe applications.
■ Tapco recommends using gross x .75, for usable capacity
✽ Buckets can be drilled for 1/4" or 5/16" bolts, please specify. 1/4" is standard.
✝ Buckets can be drilled for 5/16" or 3/8" bolts, please specify. 5/16" is standard.
Style:
AA
Design:
Slow speed centrifugal discharge.
Material:
Carbon Steel, Stainless Steel, Aluminum.
Method of Manufacture:
Fabricated.
Standard Construction:
The AA style bucket utilizes a 4-piece design consisting of two end plates, body and wear lip with the ends continuously welded to the body. 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 or hard bead welds.
Material Thickness:
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 or nonmetallic AA 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 for pulleys 6" in diameter and over. No. 3 Eclipse slotted head elevator bolts are recommended for pulleys under 6" in diameter. 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.
