Dura-Buket | Plastic Elevator Bucket

America’s Original Plastic Bucket
SS Shape for Superior Filling and Discharge
60+ Years of Performance

Center Brace on wide parts
Symmetrical Profile

Cleaner Discharge
Tapered End Cap Design

The SS or Super Strength Dura-Buket is America’s original plastic elevator bucket. The Super Strength elevator bucket has been running for over 60 years. It is designed at a 45-degree discharge angle, and can be spaced closer on a belt giving a clean superior discharge. This bucket is lightweight and tapered for easy shipping and storage. Minimum Spacing is nominal projection plus 1″. The SS is a versatile design that performs well over a broad range of speeds and applications.

Dura-Buket Low Profile Option

The LP or Low Profile Dura-Buket is a modification to the original plastic elevator bucket, the SS. It is designed at a 45-degree discharge angle and can be spaced closer on a belt giving a clean superior discharge. This bucket has a reduced height modification for closer vertical spacing on the belt. The low profile system allows more buckets per foot of elevator belt. When upgrading to Low Profile buckets horsepower requirements must be evaluated due to increased capacity.

Other Considerations

DRILLING: Elevator buckets are manufactured without a drill pattern. Special drilling or punching can be accommodated upon customer request.

VENTING: Available as needed. See venting options in our catalog.

DIGGER BUCKETS: Use slightly larger metal digger elevator buckets to help loosen material in the elevator boot section that has set up or hardened, thereby reducing abrasion on the plastic buckets. Call for details on Metal Digger elevator bucket options.

SPACING: See elevator bucket spacing details in the size chart (depending on materials and speeds, smaller and larger spacing may be used).

INSTALLATION: Use a #1 standard elevator bolt or Sabre-Tooth elevator bolt for installation. Designed to be used with fender or flat and lock washers and hex or locking nuts. If buckets are being installed on chain, use hex head bolts, nuts and washers.

FDA: Both the urethane and polyethylene are designed to FDA specifications for direct contact with food products.

Venting an elevator bucket aids in bucket fill and discharge with light, fluffy materials. Lightweight, fluffy materials, those that are extremely dense or flow poorly can be difficult to handle in bucket elevators at high speeds. Because these materials tend to trap air when being handled by an elevator bucket, venting provides air relief to assist in their filling and discharge. Commodities for venting include flours, meals, feed mash, DDG’s or screenings. As these materials enter the bucket, air is released through a series of vent holes in the bottom of the bucket allowing for a more complete fill. These vent holes also allow air to re-enter the bucket, which facilitates full release of product into the discharge. Standard hole diameter is equal to the size of the bolt mounting holes in vent pattern #1, all other vent patterns will have 11/32” diameter holes unless otherwise requested by the customer.

ADDITIONAL SPECIAL DRILLING AND VENTING CHARGES

Drilling any diameter hole over 13/32″
Bolt Hole centers closer than 1-3/4″
Side drilled buckets except standard peanut buckets
Special Venting requirements such as extra holes, change in hole diameter, etc.
Quoted prices subject to change due to special drilling and venting requirements

#1 Vent

Same holes in body as bolt mounting holes.

#2 Vent

One row of holes on 1-1/8″centers

#3 Vent

Two rows of holes on 1-1/8″centers.

#4 Vent

Same as #3, plus three holes in each end cap.

Custom Vent

Vented as required.
