A hydraulic coupler is a power transmission system that utilizes oil to transfer energy between two rotating shafts. It operates by the speed difference between the input and output shafts, generating a flow of fluid that transmits torque. This allows for smooth connection and disconnection of mechanical components without the need for direct contact between them.

This achieves a progressive start on the secondary shaft by overcoming any inertia it may have. Furthermore, by separating the two mechanical components, it prevents a lock or overload on the secondary shaft of the transmission from being directly transmitted to the driving machine (primary shaft). Finally, our couplers allow for the variation of power transmission from the main shaft to the secondary one through the control of oil used in the coupler. Thanks to this adaptability, we can control the output speed of the shaft.
