AGRICULTURAL STYLE FOR HANDLING:
GRAINS, FEEDS, FERTILIZERS, SEEDS, SALT, SAND,
CHEMICALS, and FOOD PRODUCTS
STYLE:CC-HD (Heavy Duty) and U-HD (Heavy Duty).
DESIGN: High speed centrifugal discharge.
MATERIAL: High density linear polyethylene.
METHOD OF MANUFACTURE: Injection molded.
COLOR: Blue. White, special order for four, sugar, etc..
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.
STANDARD DRILLING: No Charge.
SPECIAL DRILLING: Any pattern and hole diameter can be provided at
minimal cost.
VENTING: Available in five standard patterns. See page 78 for
specifcations.
USABLE CAPACITY: Net or usable capacity could range from 10% to
20% above water level. For engineering purposes Tapco recommends
using WL (Water Level) + 10% for usable capacity.
SPACING: Minimum bucket spacing has historically been nominal
projection plus 2". Many style CC buckets, however, are being used at
projection plus 1", and some even closer. For engineering purposes
Tapco recommends using nominal projection plus 2".
INTERCHANGEABILITY: Can be intermixed with existing steel or
nonmetallic buckets. Some consideration should be given to 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. Blue pigment meets
Regulations No. 175.300 and 177.2600.
UV RESISTANCE: No UV (ultraviolet) stabilizers are added to Tapco
buckets because most elevator buckets are enclosed in casings.
Tapco buckets should not be exposed to direct sunlight for extended
periods of time.
RECOMMENDATIONS: Polyethylene buckets are ideal for use with grains,
feeds, fertilizers, seeds, food products, chemicals, sand, salt and most
free fowing agricultural products handled in bucket elevators.
LIMITATIONS: Polyethylene buckets should not be used with the following:
(1) Materials over 200°F/93°C. (2) Sharp edged materials such as
crushed glass or oyster shells. (3) Large dense materials such as
gravel and ores over 3/8" diameter. (4) A few extremely abrasive and
sluggish materials such as dried whey, some pellets and extruded
feeds. (5) Some severe soybean and rice applications.
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 set up
with moisture, a Tapco steel digger bucket should replace every 10th
polyethylene bucket. See page 24 for specifcations
