    *The crane operator must make sure the cage is placed on a solid level surface to make sure the cage will not tip, roll or fall over during use.

    *No one should stand under or near the cage when it is being lowered into or out of the excavation. 

    *No one should manually attempt to move the cage while being lowered into the excavation.

    *Once the cage has been lowered to the desired position bracing can be placed around the cage to help secure the cage from falling over.

    *The amount of bracing required can very depending on but not limited to the surface conditions, cage placement, cage height and cage contents.

    *Bracing may shift or settle into the ground depending on surface conditions.  Bracing may need to be adjusted if there is any sinking or shifting.

    *If necessary the cages can be lined up side by side with the back of the cage against the bank and chains facing the front.

    *Nothing should be placed in the cage other than the intended product.

    *To increase safety cages can be placed back to back and side to side.

    *The taller the cage the less stable they will be.  Extra care should be taken.

    *If cages need to be placed outside the excavation they must be placed a minimum of 1.8 metres from the edge.

    LOADING AND UNLOADING

     

    *Loading and unloading the cage should be done in a manner that will not upset the stability of the cage.  E.g.: Do not unload one side of the cage all at once while leaving the other side full.  This may cause the cage to tip, roll or fall.

    *An example of how to unload a standard form cage of 24” panels would be to remove approximately 5 to 6 panels from one side, then manually lay the other forms one at a time to the opposite side of the cage in a controlled manner.  Then remove forms from the opposite side.

    *It is recommended that people using this product check the cage’s stability as they are loading and unloading each form to make sure the cage is still stable.

    *When loading and unloading the cage it is important to pay attention that the forms do not shift.

    *Failure to keep the cage balanced may cause the cage to tip, roll or fall, possibly causing injury or death.
