The 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.

Features

  • Reduces weight on elevator up to 80%
  • Up to 25% more capacity than cast iron buckets
  • Cleaner discharge
  • Non-corrosive, non-sparking
  • Thicker walls, heavy front digging lip
  • Heat, impact and abrasion resistant

Benefits

  • Lowers elevator maintenance
  • Reduces energy usage
  • Extends bucket life
  • Decreases elevator down-time
  • Easier to install and replace
  • Reduces build-up in bottom of buckets
  • Saves money versus carbon steel

** Actual dimensions may vary slightly on all elevator buckets, depending on specified raw material.

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 this 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.
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. A locking device should always be used.
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.
Spacing: PROJECTION x 2 = STANDARD VERTICAL SPACING (depending on material and speeds, smaller and large spacing may be used).

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, it is necessary to provide air relief to assist in their filling and discharge. Materials in this category might be various flours, meals, feed mash 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.

Generally hole diameter is equal to bolt holes drilled for attachment. In certain cases, larger diameter holes may be necessary.

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 insure that the material will discharge cleanly.


Venting Option 1
#1 Vent
Same holes in body as bolt mounting holes.
Venting Option 3
#3 Vent
Two rows of holes on 1-1/8"centers.
Custom Venting Option

Vented as required.
Venting Option 2
#2 Vent
One row of holes on 1-1/8"centers.
Venting Option 4
#4 Vent
Same as #3, plus three holes in each end cap.
