The capacity of the bin shall be sufficient to contain the discharge of three dump haul trucks. A level detector shall be installed to shut off the power supply to the flight bar feeder in the event of the level of run of mine coal inside the tip bin reaching a pre-determined minimum height. The tip bin shall be lined with impact and wear resistant material (VRN 400), where impact may occur. The angles of the tip bin sides shall be such that no hang-up of material occurs.

The design of the tip bin shall take into consideration the flow of material so as to exclude any high wearing/impact areas. The outlet of the reception bin shall be of such a size and shape to ensure that mechanical interlocking of large particles will not choke the outlet.

Walkways shall be provided around the outside of the tip bin for safe access to all parts of the tip bin to allow for easy removal of the liners. The tip bin support steelwork shall be so designed to withstand the impact forces generated when a full load is dumped into an empty bin.
