MAXI-TUFF®
AA Elevator Bucket: Urethane |
|
 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. |

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 |
|
Adapter plates: |
Recommended for chain mounting
applications. |
|
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). |

COMMENTS |
Best for high heat applications, with
tough impact and abrasion needs. |
Most flexible and abrasion resistant.
Resists product sticking and sharp
cutting particles. |
Economical, high density polyethylene.
FDA approved material for handling food
grade products. |
For specific requirements,
such as extreme temperature, abrasion,
special color or product discharge. |
|
|
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.
|
|
 #1 Vent
Same holes in body as bolt mounting
holes. |
 #2 Vent
Twice as many holes in body as bolt
mounting holes. |
|
 #3 Vent
Two rows, or four times as many holes as
bolt mounting. |
 #4 Vent
Same as #3, plus three holes in each end
cap. |
|
 Custom Vent
Vented as required. |
