Aumund Fördertechnik GmbH has tasked its R&D team to make new chain developments and improvements to cope with the continually increasing demands on bucket elevator chains.
The Germany company said its own chain manufacture gives it independence from outside suppliers and total ownership of control and quality of its chains, enabling it to rapidly bring to market new developments and improvements in chains, alongside its standard portfolio.
TILEMANN Ketten & Komponenten has produced bucket elevator, reclaimer and conveyor chains as well as specialised components, for more than 100 years with a tradition of precision and process reliability.
Now that this specialist manufacturer, with its modern manufacturing machinery and more than 25,000 references in high-quality chains and key components, belongs to the Aumund Group, Aumund Fördertechnik has its own source, which not only supplies to Aumund but also to Schade Lagertechnik GmbH and Samson Materials Handling Ltd (both Aumund Group Companies), as well as to renowned general contractors for original equipment, and other prominent globally active end customers.
“Purely on the face of it, today’s bucket elevator chains look hardly any different from examples 15 years ago, but with bucket elevator chains the ‘inner values’ are more important,” the company stated.
“Aumund uses innovative materials which enable ever-increasing tensile strength and, importantly for tall bucket elevators, an ever-decreasing weight component. In its production process TILEMANN favours improved heat treatment methods and optimised manufacturing and assembly procedures.
“One example is continuous monitoring of the press-in pressure of the bolts during assembly, in order to confirm that the fit is exactly within the specified range. This creates an optimum interaction of the chain with the drive and tensioning segments. Process checks are carried out at shorter intervals all the time, and documentation is issued in more and more detail, facilitating exact trace of chain supply.”
Aumund added that it has invested several millions of euros in manufacturing at TILEMANN and in so doing has optimised the production process and increased productivity.
“In order to meet the increased demand in the market for chains and to further decrease lead times for customers, Aumund is planning further investment in production in 2020 by expanding the factory facilities,” the firm concluded.
