TEMPERATURE RANGE:
-60°F to + 212°F/-51° C to + 100°C.
FLAMMABILITY:
The urethane used in Tapco buckets, meets the criteria
of the Underwriters’ Laboratory Bulletin No. 94 HB. It has been tested
under ASTM Test No. D635 and has a burn rate of 0.76”/min. it also
meets approval under motor vehicle safety standard No. 302, with a
burn rate of 0.0”/min.
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.

EXTREME ABRASION RESISTANCE, TOUGH AND FLEXIBLE,
UNIFORM DISCHARGE, NONSPARKING, NONCORROSIVE
TECHNICAL INFORMATION:
INDUSTRIAL STYLE FOR HANDLING:
PELLETIZED OR EXTRUDED FEEDS, SOYBEANS, FERTILIZERS, OYSTER SHELLS,
SALT, SAND, CHEMICALS, and OTHER ABRASIVE PRODUCTS
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.
Large flat steel (fender) washers must be placed inside the bucket
under the nuts.
Check elevator for proper clearances.
FDA STATUS:
Our standard urethane does not meet the requirements for
FDA approval. FDA approved urethane is available, special order.
RECOMMENDATIONS:
AA urethane buckets are ideal for use with
foundry sand, gravel, coal, fertilizer, clay salt, andmany other industrial
materials. They are excellent for extremely high throughput elevators
LIMITATIONS:
Urethane buckets should not be used on the following:
(1) Materials over 212°F/100°C. (2) Large dense materials such
as gravel and ores over 3/8" in diameter. (3) Some sharp sluggish
materials such as large glass cullet. (4) Prolonged exposure to water
or steam.
CAUTION:
Welding and cutting on elevator legs without taking proper
precautions is extremely dangerous and can cause a violent explosion.
Urethane buckets can be ignited and will burn from improper welding
and cutting. Prolonged exposure to water or steam.
IMPORTANT:
When elevating certain materials that harden or setup with
moisture, a Tapco metallic digger bucket should replace every 10th
urethane bucket. In some instances ductile iron AA style buckets will
not have sufficient projection to protect the urethane bucket. It will be
necessary to use a pad or spacer behind the digger bucket. Contact
Tapco for recommendations.
