The starting signal was given for the development of the first elements of the pipe connection system in 1972. Within a short time, the range of products was not only extended by developing new clamping elements but also by starting the new production of linear adjusting units. In 1983, these two groups were supplemented with the first aluminium profile, the pioneer of the BLOCAN®-profile system.

Its innovative energy helped the young enterprise gain increasing importance and economic strength. The high investment costs, however, soon required a powerful partner who was found in 1987 with the world-wide operating Phoenix Mecano Group. Supported by the Swiss concern, RK Rose+Krieger grew to an internationally expanding enterprise.

Today, RK Rose+Krieger has a leading position in the area of the construction of connection and positioning systems. This is an advantage that can only be maintained in the future in close cooperation with our customers.



Chronology of the milestones

milestones 2015


In 2015, RK Rose+Krieger was once again named one of the TOP 100 most innovative SMEs in Germany.

RK presented its new monitor mountings for industrial applications at the Hannover Messe for the first time.

A 3000 N version of the RK Powerlift M series of lifting columns was presented. What's more, the Multilift II lifting column is now also available as a "telescope" version with an optimum height/stroke length Ratio.

milestones 2014


RK Rose+Krieger is named one of the 100 most innovative SMEs in Germany for the third year in a row.

The PROFILE TECHNOLOGY catalogue is implemented based on the new philosophy of “application-oriented classification”. The chapters are entitled Construction Profiles, Functional /Special Profiles and Heavy Duty Profiles, and simplify the selection of the products required.

The RK Duoline linear actuators are optimised further for clean rooms and successfully tested. The relevant test certificates required under EN ISO 14644-1 are issued for the “Clean” version.

The new generation of Multilift lifting columns is presented and is specially designed for synchronous applications. Easy commissioning guaranteed – Plug & Work!

R28 adapter sleeve – New reducing bushes enhance flexibility and compatibility with tube connection Systems.

The new CONNECTING TECHNOLOGY selection guide is highly application-specific and enables the suitable element to be found quickly.

The RK Duoline 120 is the third size which sets a new industry benchmark for linear products.

RK SyncFlex for lifting columns and electric cylinders prevents errors in installation and commissioning, reducing costs and saving time.

WEB relaunch is unveiled. The new website is closely based on the application-oriented product structure.

The new catalogue for tube connectors “CONNECTING TECHNOLOGY” is published. Classification is based on the application for the low load, medium-to-heavy load and shock-proof load ranges.

The updated version of the EPX linear units which have been tried and tested over many years is presented. The new EPX generation is compatible with its predecessors, offers higher precision, has a longer service life and is easier to maintain.
