Stacker Cranes Safely Monitored

- even at Lowest Temperatures

Customer Success Story

Zentis GmbH & Co. KG in Aachen uses large stacker cranes for storage, transfer and retrieval. In order to monitor the large and difficult-to-access moving components in the cold and frozen storage and to avoid unplanned downtime, the logistics department was looking for a predictive maintenance solution. The company opted for the Schaeffler ProLink CMS monitoring system. Schaeffler experts and the local authorized distributor KSA Kubben + Steinemer GmbH & Co. KG (KSA) implemented an intelligent measuring concept to adapt to the customer's requirements.

Challenge

“We are looking for a monitoring solution for our stacker cranes that can reliably take measurements despite inconsistent measuring conditions and ultra-low temperatures in order to protect us from unplanned downtimes.“

Solution

To monitor the stacker cranes, one Schaeffler ProLink CMS and five sensors (bearing guards) were installed on each stacker crane unit.
 
In order to be able to perform meaningful vibration monitoring, the original measurement concept had to be changed in the multi-channel condition monitoring system. Schaeffler experts achieved this by breaking down the short, slow travel times into many short measurements. Extreme impacts could then be determined from these.

The temperature challenge was solved as follows: In the cold storage area, the ProLink CMS system was installed in the switch cabinet; in the frozen storage area, the system was placed in heated control cabinets that escort each run. The sensors could be attached to the measuring point using a cold-resistant adhesive compound.

What's Special

Zentis KG is absolutely satisfied with the monitoring solution that meets all their complex requirements. It was similar when Zentis was looking for a solution for their pallet lifters years ago. That challenge then was solved with the SmartCheck monitoring system and a SmartConnect Box.
