CC-HD “Heavy Duty” Elevator Bucket 

Severe Duty Urethane

The CC-HD bucket is the realization of a vision that our founders, Paul D. Taylor and Ted W. Beaty, had in the early 1970s. They wanted to eliminate the inherent problems of steel buckets, so they created a strong, resilient plastic bucket. Stronger, safer and more efficient than steel buckets, the CC-HD bucket is the gold standard of performance, durability and cost effectiveness.

Why Urethane?

This severe-duty, non-corrosive, non-sparking material is tough yet flexible. These clean-discharging, lightweight buckets are a great choice for abrasive or high-throughput applications, because its resilience causes less product damage and reduces the product failure that can cause backlegging.

▲ 350-160 bucket was designed to fit Hunter Mfg. Grizzly elevators

Standard bolt holes drilled on the WL (Water Level) line ± 6.35mm

Style:

CC-HD (Heavy Duty)

Design:

High speed centrifugal discharge.

Material:

Prime virgin thermoplastic urethane.

Method of Manufacture:

Injection molded.

Color:

Beige (Tan).

Temperature Range:

-60°F to + 212°F/-51° C to + 100°C.

Durometer Range:

Shore D 60-70.

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.

Standard Drilling:

No Charge.

Special Drilling:

Any pattern and hole diameter can be provided at minimal cost.

Venting:

Available in five standard patterns. See catalog for specifications. Venting page.

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. 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.

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:

Urethane buckets are ideal for use with pelletized high fat and molasses feeds, extruded feeds, severe soybean, rice and barley applications and other abrasive agricultural products. 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.

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.

Important:

When elevating materials that harden or set up with moisture, a Tapco steel digger bucket should replace every 10th urethane bucket. Contact Tapco for recommendations.
