EMG Automation GmbH was founded on 22 June 1946 as a subsidiary of the “Nationale Automobilgesellschaft (NAG)”. The company produced brake lifting devices for use in industrial brakes. In 1977 the majority company EMH was founded in Brazil, which supplies the South American market with electromechanical and electro-hydraulic components. In 1980, EMG acquired Bielefeld Servo-Technik (BST) and has since then expanded the worldwide network of today's BST eltromat International GmbH. In 1995, BST acquired a majority shareholding in the US company Pro Mark Technologies, which means that the EMG Group has been represented on all continents since then. In 2003, the headquarters of EMG's parent company Elexis AG were relocated to Wenden (Sauerland). 

More than 70 years of EMG, which is also more than 70 years of continuous growth and consistent development of new markets and sales areas. Today, EMG is a global company with more than 1000 employees. We supply our products to OEMs (Original Equipment Manufacturers) around the world and realise turnkey solutions for end customers. Our bond with Wenden ensures we remain grounded, while our global presence safeguards our future.

EMG brake thrusters in ports: 100% safety

Brake thrusters are crucial components in the braking systems of container gantry cranes and harbour crane systems when it comes to safety. Huge investment and not least human lives depend on brake thrusters working reliably. For more than 70 years, EMG in Wenden has been producing brake thrusters that have been setting standards with their safety and durability. More than two million of these brake thrusters are now in use worldwide, and EMG is the global market leader with its brands ELDRO® and ELHY®. Over the course of time, the brand name ELDRO® has become synonymous with brake thruster, but ELDRO® is only present where EMG appears on the brake thruster. The ELDRO® slogan, “The Original. Be safe.” emphasizes the high quality standard.
