3.2    Storm water Pit Cover Removal


3.2.1 Hinged Pit Grates


To open a hinged pit grate follow the following steps:


      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.
