    1. Insert the lifting hooks beneath the grate. (Position indicated in Plate 2)
    2. Check hinge point is not damaged and debris is not caught in the hinge area.
    3. Note many cast iron hinges are not hinged securely (to enable the removal of the grate). This may
       result in the pit grate not being able to sit in an open position. Additionally the hinge pins may also be
       damaged or corroded, which may allow for the pit grate to fall into pit. Such pit grates can be
       removed using the method indicated below for non-hinged grates.
    4. Fully open pit grate, ensuring that the grate will stay in the open position without any external forces
       applied. Grates which do not remain open without being held should be removed or secured during
       cleaning or maintenance activities. Plate 3 and Plate 4 indicate the grate being opened and grate
       resting freely in the open position, respectively.

3.2.2 Non-Hinged Pit Grates

To remove a non-hinged pit grate:
    1. Place lifting hooks beneath grate, where possible in the four corners of the grate (Plate 6). Concrete
       lids may have Gatic lifting points, a key arrangement or holes in the lid, as such special equipment,
       such as Gatic lifters may be required.
    2. Position each person either side of the grate. (Plate 7)
    3. Lift the grate, ensuring that good heavy lifting posture is used at all times.
    4. Place the grate on an angle on the gutter, to allow for the lifting hooks to be removed. (Plate 8)
    5. For extremely heavy one piece grates and concrete Gatic covers, insert the lifters in place and slide the
       lids back. Note some lids may still require two people. (Picture required)
