AA Elevator Bucket
Cast Aluminum *Special Order Only*
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 Aluminum?
Aluminum buckets should be substituted for nonmetallic buckets when the heat becomes too excessive and the application requires a lighter weight, non-sparking, corrosion-resistant bucket.
Features
- Lightweight
- Corrosion Resistant
- High-Temperature Range
- Nonsparking

■ 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:
Centrifugal discharge.
Material:
Aluminum.
Method of Manufacture:
Cast.
Color:
Silver.
Temperature Range:
-60°F to + 400 °F/-51° C to + 204 °C.
Drilling:
No charge for standard belt or chain drillings when order totals 50 or more pieces of the same size. Contact Tapco for quotation on orders of less than 50 and/or special drill pattern requirements.
Venting:
Available upon request. Contact Tapco for recommendations.
Usable Capacity:
Tapco recommends using 75% of gross, (100%) capacity.
Spacing:
A common spacing would be nominal projection plus 4" however, both closer and greater spacings may be used depending upon the application.
Interchangeability:
Can be intermixed with existing metallic or nonmetallic buckets. Some care should be taken that the leg does not become too far out of balance. Bucket projection varies by manufacturer and material. Check elevator for proper clearances. Contact Tapco for recommendations.
Installation:
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 (Fender) washers must be placed inside the bucket under the nuts. Check elevator for proper clearances.
FDA Status:
Aluminum used meets FDA requirements.
Recommendations:
AA aluminum buckets are ideal for use in nonabrasive applications where a lightweight bucket is desirable.
Limitations:
Polyethylene buckets should not be used with the following: (1) Materials over 400°F/204°C. (2) Sharp-edged material such as crushed glass or oyster shells. (3) Large dense materials such as gravel and ores.
Caution:
Welding and cutting on elevator legs without taking proper precautions is extremely dangerous and can cause a violent explosion.
