ELHY® Electrohydraulic thruster
ELHY® Electrohydraulic Thruster – Reliable Performance for Industrial Braking
The electrohydraulic thruster from the ELHY® EB series is engineered for demanding industrial brake applications, offering outstanding reliability and safety. These thrusters are ideally suited for sectors such as mechanical engineering, materials handling, and applications requiring effective industrial brake solutions, making them a trusted component in modern drive and brake systems.
Design, Functionality and Advantages
ELHY® electrohydraulic thrusters convert electrical energy into precise linear movement using hydraulic force. Each device features a robust three-phase asynchronous motor that runs in an oil-filled housing, coupled with an axially movable piston and a guide cylinder. The entire unit is securely fixed by cast feet on the housing, ensuring a stable installation even under harsh industrial conditions.
