EMG Elektro Mechanik GmbH was founded on 22 June 1946 as a subsidiary of Nationale Automobilgesellschaft (NAG), a wholly owned subsidiary of AEG. It is headquartered in Wendenerhütte in southern Sauerland. The name of the town is based on the iron smelting works, which was built here in 1728.
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 is the specialist when it comes to intelligent and complex automation solutions and, in our capacity as a technological leader, we are the supplier of choice for our customers.
The main areas of application for series products, individual components and complex system solutions from the EMG group include continuous production processes in the metal, paper and plastic sectors, as well as in the foil and tyre industries.
Electrohydraulic thrusters ELDRO® and ELHY®
Highest quality – Maximum safety
Mode of Operation
All elements of a hydraulic actuation system are combined in the electrohydraulic thrusters from EMG to produce a compact assembly. When switched off, the hydraulic piston with the piston rod is located in its lower end position. When switched on, the hydraulic pump pumps the operating fluid beneath the piston and, in doing so, generates the hydraulic pressure here. This moves the piston up to the maximum stroke path. When doing this, the counterforce – which is generated through an integrated brake or return spring, or an external load (e.g. a brake) – must be safely overcome.
The maximum stroke path of the devices can be externally arbitrarily limited. This can be the case if the brake to be actuated only requires a reduced stroke path for complete opening. In the respective piston end position, the power consumption of the motor reduces in comparison to the power consumed during the lifting process due to the laws of hydraulics. The pressure in the device reaches its maximum value here. The drive motor is therefore relieved in the resting position of the piston. Mechanical overloading of the devices is not possible.
