Their are 6 bolt holes in a 4ft side of steel deck, therefore 12 bolts and 12 nylon lock nuts will be required. I have chosen Nylon Lock Nuts as when in the air the platform will be suspended above peoples heads. The nylon lock ensures that the nuts cannot come loose and therefore are safer than standard M10 Nuts. | Their are 6 bolt holes in a 4ft side of steel deck, therefore 12 bolts and 12 nylon lock nuts will be required.

Once the decks have been bolted together, the next step would be to wrap a round sling around each corner in a basket formation and link this, with a shackle to one end of the wire rope bridle. I would also do this at the joins on the Up Stage edge of the platform. | Once the decks have been bolted together, the next step would be to wrap a round sling around each corner in a basket formation and link this, with a shackle to one end of the wire rope bridle. I would also do this at the joins in the decks on the Up Stage edge of the platform, as an extra safety precaution. | ||
Once this has been done I would lower the required bars in, in this case Bars 29 and 25, and attach the other end of the bridle in the same way as before, via a round sling in a basket formation and a shackle. | Once this has been done I would lower the required bars in, in this case Bars 29 and 25, and attach the other end of the bridle in the same way as before, via a round sling in a basket formation and a shackle. | ||

Their are 6 Wire rope bridles in the structure, each with a SWL of 500kgs. This is far greather than the safety factor of 8 which should be standard in the theatre industry. Their are 12 round slings in the structure, each holding 1/6th of the overall weight. Each round sling is rated at 2000kgs when used in the basket formation, this has a sufficient safety factor. | Their are 6 Wire rope bridles in the structure, each with a SWL of 500kgs.

Also their are 12 0.5t Bow Shackles, which also would hold 1/6th of the weight, therefore having a more than sufficient safety factor, to work safely in British Theatre. | Also their are 12 0.5t Bow Shackles, which also would hold 1/6th of the weight, therefore having a more than sufficient safety factor, to work safely in British Theatre. | ||
