maxi-tuff aa industrial plastic elevator bucketThe Maxi-Tuff AA centrifugal elevator bucket has the traditional shape of a cast iron bucket. This bucket has a heavy reinforced lip and corners with a thickened back wall for mounting strength. Standard spacing is projection x 2. The most common applications include handling stone, sand, gravel, coal, fertilizer, clay, salt, limestone and concrete. The Maxi-Tuff AA bucket is the best bucket for tough, abrasive industrial applications. 

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: PROJECTION x 2 = STANDARD VERTICAL SPACING (depending on material and speeds, smaller and large 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. Special food grade nylon is also available for high heat applications.

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.

When elevating powdery materials such as cement in the Tiger-Tuff, a minimum of two rows of 3/8″ diameter vent holes are recommended to help ensure that the material will discharge cleanly.

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.

Please call for guidance on bucket venting.
