Flat design for confined installation situations
The Bolt Tensioning Cylinder Type ES was specially developed for applications with limited installation space. Its flat design allows it to be used in axially confined and radially free installation conditions, as is often the case with foundation bolt connections, heat exchangers or flanges.

Compatibility with common fasteners
Type ES is compatible with all common fasteners such as hexagon nuts, round nuts (ISO 4032, DIN 2510, EN 14399), ITH round nuts RMS and RMZ as well as heavy hex nuts. Customer-specific designs can also be easily implemented to meet individual requirements.

Modular design for maximum flexibility
Thanks to its modular design, the Bolt Tensioning Cylinder type ES can be adapted to different bolt/nut configurations using interchangeable bushes, support sleeves and turning sleeves. This versatility makes it the optimal solution for precise and repeatable assembly processes.

Optional equipment and safety
Type ES offers additional options such as nickel-chromium coatings, multi-tensioning connections and safety features such as a patented breaking load safety device and cycle counter. These features ensure maximum work safety and considerably extend the range of applications.
