PLOKE Engineering AG

We are an experienced Swiss engineering company with a focus on globally unique bolting solutions based on the MJP principle (mechanical Multi-Jackbolt Pretensioner) for absorbing the greatest forces.

Our field of activity covers all areas in which large, secure and, above all, releasable bolted connections are required. We calculate, develop, design and produce the best technical and economical bolting solutions for large dimensions and high, precisely adjustable pre-tensioning forces in accordance with the specific requirements of our customers and on the basis of our high-quality mechanical Multi-Jackbolt Pretensioners.

We offer our services and products throughout Europe. Our customers are advised personally and competently on site by our sales engineers and distribution partners and are also supported during the installation of their bolting solution or during maintenance work.

Benefit from our many years of experience as a technology leader for highly stressed large-diameter bolted connections. We are happy to put our comprehensive know-how at your disposal and look forward to a successful cooperation.

Founded in 2014 - Experience since 1988

Company owner Robert Ploke has been active in this field since 1988. He has supervised countless bolting projects on site throughout Europe in many areas of heavy industry. Due to his many years as co-owner and managing director at the former company P&S Vorspannsysteme AG in St. Gallenkappel, whose co-founders were Rolf Steinbock and his father Gerhard Ploke, he is very familiar with large bolted joints and their special requirements (see also History).
