Ball Joints




The great advantage of this ball joint type is an easy and quick connection / disconnection of a floating pipeline or hose, mostly used between a floating pipeline and cutter suction dredger or pontoon. That is the reason that this product is also known as quick release ball joint. The female part is positioned on the dredger or pontoon and male part is connected to the floating pipeline or hose. Normally the pinch ball joint can be operated manually, but the quick release execution can be equipped with hydraulic cylinders on the female part for remote control.

The pinch ball joint exists of three main parts: female part, male part and retaining ring. The retaining ring couples the male part in the female part. The retaining ring is executed in 2 parts and is hinging in the female part.
