The hydraulic system includes operating cylinders and a hand pump. A typical access cover panel would take around 60 seconds to open from a closed position.

The hatch closes on a release of the hydraulic oil from the cylinder. The weight of the cover is sufficient to push the cylinder closed.

Pneumatic Operation

Pneumatic operation

The pneumatics provide a clean and efficient way of operating our hatches. This method is designed for the environments where compressed air is freely available or is preferred to hydraulic cylinders or electrical actuators.
