About us

For more than 45 years Heynck has been a manufacturer and partner for the production of new high-performance hydraulic cylinders for the industrial and mining applications, and for the repair and maintenance of that type of equipment. Heynck is the No. 1 professional when it comes to cylinders built for special purpose.

For the various systems in the global Pipejacking, Microtunneling and tunneling business, Heynck delivers jacking cylinders, intermediate jacking cylinders, steering cylinders, cylinders for compact jacking frames as well as telescopic slurry lines and various other accessories.

This guarantees a high degree of performance and safety, for new productions as well as for maintenance. Our many years of experience in the manufacture of products, some of which are used permanently under extreme conditions where they perform reliably, have guided us to an optimum standard of quality and length of service life in the products we build. Our in-house design department also handles the development of bespoke solutions.
