Programming of a hopper that is designed for ships to unload into. Once the product is in the hopper a truck would park under the hopper for controlled filling. A main feature of the hopper was dust control when loading.
The Hopper unit was designed by Page Macrae, electrical installation by ElectriServ and control programming by Thomson Group Ltd. Working as a team, a hopper was designed that would allow the ships to unload into the top of them with a screen entry point. The hoppers had the ability to move around the wharf depending on where they were required. Once the trucks pulled under the hopper a chute would move down into the truck trailer and fill the truck, as the filling occurred the chute would raise according to product level in the trailer. This was done so that the dust would be minimised as much as possible. The controller used for this project was a M221 Schneider PLC with a Magelis HMI for control.
