About EMHA
EMHA is a service and engineering company for rotating equipment and drive systems in shipping, offshore, industry and civil engineering. The portfolio covers engineering from concept to commissioning, noise and vibration measurements, diagnostics, continuous monitoring, high-precision alignment and 3D surveying, complete installation of machinery and drivelines, and mobile on-site machining aboard and on location. In addition, EMHA manufactures and installs piping systems and steel constructions up to execution class EXC3 according to EN 1090-2 and welds in steel and stainless steel according to EN ISO 3834-2. For machine installation, epoxy resin grouting compounds (including Chockfast, which EMHA distributes exclusively in several countries) and adjustable steel foundations are used; the company also supplies bearing materials such as Tenmat, FEROFORM and RAILKO as well as monitoring measurement systems (Techno Fysica). Headquartered in Hendrik Ido Ambacht (Netherlands) with a German branch in Norderstedt, EMHA has been active for over 60 years and is reachable around the clock.
