Industrial Buckets / Maxi-Tuff AA

With the traditional shape of a cast-iron bucket but built from your choice of four strong plastic materials, the Maxi-Tuff AA centrifugal bucket is best for abrasive industrial applications. From its heavy reinforced lip and corners to its thickened back wall for added mounting strength, this bucket soars beyond the standard expectations for toughness.

Choosing Maxi-Tuff buckets can lower your energy usage, save money, and limit elevator downtime. They lighten your elevator up to 80%, last longer than other buckets, and are easy to install and replace when needed.

Handles Abrasive Materials Without a Scratch

Maxi-Tuff AA buckets are built stronger to handle tough and abrasive materials like:

AGGREGATE

Cement

Coal

Concrete

Clay

Fertilizer

Gravel

Limestone

Potash

Salt

Sand

Sawdust

The Secret Ingredients of Our Toughest Buckets

Maxi-Tuff AA buckets come in four food-grade, high-heat, and abrasion-resistant options:

Poly: Our high-density polyethylene is FDA approved to safely handle food and grain products.
Nylon: Able to safely handle temperatures between -60°F and 300°F, our nylon works great for your hottest, high-impact, abrasive, and dense products.
Urethane: The most flexible and abrasion-resistant of the four materials, our urethane buckets are best at resisting product sticking and sharp cutting particles from your heavy, abrasive, and sticky products.
FDA Nylon: These buckets can handle temperatures up to 300°F and are FDA approved for your high-heat food applications.

Poly

Application Grains & Food Products Temperature
Range -60°F to +180°F (210°F intermittent)
FDA Approved Material Yes

Economical, high density polyethylene. FDA approved material for handling food grade products.

Nylon

Application Hot, high impact, abrasive dense products
Range -60°F to +300°F (350°F intermittent)
FDA Approved Material No

Best for high heat applications, with tough impact and abrasion needs.

Urethane

Application Heavy, abrasion, sticky materials
Range -60°F to +180°F (210°F intermittent)
FDA Approved Material Yes

Most flexible and abrasion resistant. Resists product sticking and sharp cutting particles.

FDA Nylon

Application Hot, high impact, abrasive food grade products
Range -60°F to +300°F
FDA Approved Material Yes

Best for high heat food grade applications, with tough impact and abrasion needs.

Vent Your Buckets

The right venting pattern helps you maintain elevator speed while cleanly filling and discharging light and fluffy or extremely dense and poor-flowing materials. Choose from our four standard venting options or ask for a custom pattern that best fits your application.

#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.
