Bucket Elevators
Reliable Conveying for Bulk Materials
From sensitive foods and ingredients to chemicals or building materials, WIESE bucket elevator conveying technology offers top-notch, custom solutions for transporting bulk materials. Your products are guaranteed efficient and material-sparing transportation.
Rubber Chain Technology
The WIESE Rubber Chain is the fundamental core of all WIESE Continuous and Pendulum bucket conveyors. Non-stretching rubber surrounds the vulcanized steel cables, ensuring high tensile strength while eliminating metal abrasion and the need for lubrication. From food-grade to conductive rubber, the custom rubber chains come in a variety of qualities to fit any need the application requires.
WIESE Rubber Chain
The WIESE rubber chain runs without links and is vibration-free, producing particularly low-noise (under 65 dBA). The slip-free running of the WIESE rubber chain ensures virtually maintenance-free operation.
The WIESE rubber chain is available in any length as a continuous loop or put together with link connectors.
WIESE’s quality assurance is carried out at their in-house specially built laboratory and testing area. We also make every effort to consistently ensure the development and improvement of rubber qualities.

No lubrication required - NO GREASE!
Typical lifespan of 10+ years, depending on application
No stretching, and no re-tensioning of the rubber chain is required throughout the entire lifespan
More Energy Efficient than conventional chains
Comparing WIESE Bucket Elevators
The WIESE Rubber Chain Bucket Elevators offers a variety of tremendous advantages. When comparing the rubber chain to plastic chain or metal chain installations, WIESE’s rubber chain is superior in every way. Unlike the plastic and metal chains, the rubber chain requires no maintenance, has virtually no breakdowns, and is significantly more energy efficient due to the lack of friction on the chain. WEISE is the obvious choice for bulk material handling.

Pendulum Bucket Elevators
Suspended between corrosion-resistant and lubricant-free rubber chains, the pendulum buckets can be individually tipped or rotated without affecting neighboring buckets. While in the horizontal sector and/or the product handover point, the buckets create a self-contained, seamless conveyor belt. Bucket conveyors can also be equipped with Clean-In-Place (CIP) cleaning stations for automatic cleaning with either water or compressed air.
WIESE Pendulum Bucket Elevator
WIESE’s pendulum bucket elevator is the most versatile option available and uses free-swinging buckets to allow for gentle handling, and easy, tool-free removal of buckets for cleaning. This option is especially suitable for products that require gentle and hygienic transportation.
Various layout options are also possible and include z-, c-, t-, and o- shapes.

Continuous Bucket Elevators
Continuous bucket conveyors are fully enclosed, seamless conveyor belts. Neighboring buckets are connected to each other by a flexible rubber “connecting flap” that provide a gap free connection through positive-locking, guaranteeing minimal product loss. Bulk materials can be transported both horizontally and vertically without any handover points.
All individual parts can be replaced, such as buckets or the connecting flaps, allowing for a high degree of system availability.
WIESE Continuous Bucket Elevator
WIESE’s continuous bucket conveyor uses interlocking buckets to provide improved stability, thus resulting in higher belt speed capabilities for high capacity operations. The continuous belt is long-lasting, requires less maintenance, and is particularly suitable for abrasive goods such as cement, sugar, mortar, ceramics and flint stone, as well as delicate goods such as cereals, pet food, roasted peanuts and coffee. Several layout options available including Z-, C-, Horizontal, and Cascade layout shapes.

Sanitary Design
For products that require the cleanest environments, WIESE has developed a sanitary pendulum bucket elevator. This model utilizes a tubular frame profile, so there are no horizontal surfaces or ‘dead-spots’ where dust and other debris can accumulate. All covers are removable via a two-way ‘key’, and buckets can be removed/installed without tools. Additional options such as CIP are also available.
Capacity
26 cubic feet per minute (45 cubic meters/hr)
Features
Tubular Frame Design
Choice of stainless steel or Lexan covers
Optional CIP available
All covers removable with 2-way key
Buckets removable without tools
Benefits
No 'dead spots' or horizontal surfaces
With Lexan covers, inside of elevator is completely visible
Easy access to buckets for cleaning
Quick bucket changeover

Dust-Proof Design: Inside
For applications with especially dusty products and environments, WIESE has developed a dust-proof bucket elevator. This dust-tight housing construction ensures that products and dust remain inside the housing and do not escape into the environment around them. For systems at risk of dust explosions, WIESE continuous bucket and pendulum bucket conveyors are also available with ATEX certification.
