The best pneumatic ship unloaders

Pneumatic ship unloaders VIGAN

The NIV unloaders are the largest and most efficient pneumatic unloaders. They are the result of the best and latest technological developments made by VIGAN to meet and exceed customer needs.

The NIV suction unit is a compact equipment. It consists mainly of a machine room, containing the mechanical elements, and a boom made of a tubular lattice supporting the suction pipes. The assembly is supported by a rotating slewing ring which allows the suction pipes to be positioned above the ship’s hold to be unloaded.

The cargo sucked up flows finally towards the center of this slewing ring. The suction units are protected by a large filter unit. The machine is designed to move in all directions for efficient operation and hatch reach.
