AA Elevator Bucket
STYLE: AA.
DESIGN: Centrifugal discharge.
material: High density linear polyethylene.
METHOD OF MANUFACTURE: Injection molded.
COLOR: White.
TEMPERATURE RANGE: -60° F to + 200° F. (-51° C to +93° C).
FLAMMABILITY: The high density polyethylene used in Tapco buckets
is termed “slow burning”. It has been tested under ASTM Test No.
D635. It also meets the criteria for approval under the Motor Vehicle
Safety Standard No. 302 and Underwriters’ Laboratory Bulletin No.
94. Combustion in an excess of air results in harmless by-products
(fumes) which are nontoxic.
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 on 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 washers must be placed inside the bucket
under the nuts. Check elevator for proper clearances.
FDA STATUS: Polyethylene used meets the requirements of the Food
Additives Law and Regulation No. 177.1520.
RECOMMENDATIONS: AA white polyethylene buckets are ideal for
use in applications requiring food grade components.
LIMITATIONS: Polyethylene buckets should not be used with the
following: (1) Materials over 200°F/93°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. Polyethylene buckets can be ignited and will burn from
improper welding and cutting.
IMPORTANT: When elevating certain materials that harden or setup
with moisture, a Tapco metallic digger bucket should replace every
10th polyethylene bucket. In some instances ductile iron AA style
buckets (See page 43) will not have suffcient projection to protect
the polyethylene bucket. It will be necessary to use a pad or spacer
behind the digger bucket. Contact Tapco for recommendations.
