In 2010, Page Macrae Engineering were tasked with providing a solution for POAGS Darwin
operation (now known as QUBE). This project represented a major research and development effort to deliver what the customer required, in particular assisting the client in complying with strict environmental standards regarding dust emissions.
Australian ports are very conscious of their environmental foot print, especially around dust emissions. As in New Zealand, they often share their harbour resource with recreational users, and want to ensure they are not damaging that resource.
These newly designed and built hoppers
weighed approximately 35 tonne each and represented 7500 man hours of work from our design and construction crew. The hoppers provide the vital link between removing bulk cargo from a ship’s hold, and discharging into waiting trucks as swiftly as possible, while emitting as little dust as possible.
Special discharge spouts
automatically adjust according to the height of the load in the waiting truck, sucking dust back up into the hopper rather than losing it to the atmosphere.
As part of the complete package supplied to POAGS, three diesel hydraulic bulk grabs
were supplied aiding in the unloading operation. These grabs were also newly designed and incorporated the latest mobile control system technology.
