Industrial unloader

bulkship

Overview
The NIV pneumatic ship unloader series are suction-type bulk handling units designed for large-scale ship discharge. Each unit integrates a machine room (mechanical components) and a tubular lattice boom that supports the suction pipes, mounted on a rotating slewing ring to position the pipes over the ship hold. Material is conveyed to the centre of the slewing ring and filtration is provided by a large self-cleaning filter unit.

Key features
