The HD-MAX Heavy Duty elevator bucket is a perfect marriage between durable design and economical pricing. This bucket is designed with thicker walls and reinforced front corners and lip to increase bucket life and reduce breakage.The HD-MAX bucket stands second only to the Tiger-Tuff in strength and thickness.  It is a favorite among bucket elevator manufacturers for its extra capacity and durability.

Minimum spacing is nominal projection plus 1”. The recommended belt width for a single row of buckets is actual bucket width plus 2”.

HD-MAX Low Profile Option

A reduced height for closer vertical spacing allows more buckets per foot of elevator belt. When upgrading to HD-Max 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.

HD-MAX Steel Digger

Digger elevator buckets aid in breaking up material in the bucket elevator. Diggers extend 1/4″ further than plastic elevator buckets. Weights and dimensions will vary. Tolerance is a 1/4″ on all bucket dimensions except bolt hole diameter which is 1/16″. Capacity is based off of plastic elevator buckets of similar style. Buckets available in carbon or stainless steel. Additional AR wear lips, back plates and venting available upon request. Buckets available in other gauges including 14GA, 12GA, 10GA, 7GA, 1/4″ thick.

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
