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

Wiese rubber chain used for bucket elevators in food production and manufacturing lines

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.

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

Bucket elevators conveying and transporting pretzels through a food production line

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

Bucket elevators interlocking through a food production line

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.
