Rigter Handelsonderneming can supply central lubrication on many types of sorting grabs.
After a long test period in harsh conditions, it is now available in series production.
All pins and bushes receive enough grease evenly throughout the day, and the slewing ring is also lubricated. It can also be lubricated manually if necessary.

The system is robustly concealed in the grab and can hardly be damaged.
They are increasingly seeing operators with a grease gun allergy or that people simply do not know how often to lubricate and where the grease nipples are located.
This has now solved a problem. Now, depending on the use, the reservoir must be refilled every 2 to 3 weeks.
Daily checks are still necessary, but Rigter Handelsonderneming believes that this is a solution for many companies.
