This Hydraulic Trailer Coupling is with hydraulic brake, which is a safe brake system.
This braked Hydraulic Trailer Coupling is more stronger and durable as it is cast steel structure and galvanized surface finish.
Hydraulic Trailer Brake Coupling is designed for 50mm tow ball.
This Hydraulic Trailer Coupling is assembled with cylinder which is connected with hoses.
The principal of this type of coupling is a sliding shaft attached to the tow ball housing of the coupling. As the tow vehicle slows down the force of deceleration is passed through the coupling shaft and pushed on a linkage connected to a hydraulic cylinder providing hydraulic pressure to a braking system to make trailer stop.
