Installing The Instrument On The Frame

  • Move the pallet and frame towards the front of the unpacking room.

  • Bring the instrument and cart out of the cleanroom.

    NOTE: position the cart so that the taller heavier side of the instrument will set down on the side of the frame with the most wire-rope isolators.

  • Install the scale between the load spreader and the crane, and place the lifting fixture in the instrument+cart position.

  • Install the triangle stabilizing rope ratchets, leaving them loose.

  • With the crane, carefully position the load spreader over the table.

    NOTE: be sure to guide both ends of the load spreader so it does not contact the instrument

  • Attach the load spreader to the cart. Two shackles are used to extend the length. The hooks should be placed opening up.
