Transfer Tower

 

The Transfer Tower consists of two parts: The Lower Tower Area and the Transfer Tower (or Upper Tower Area).

The Lower Tower Area is a 30’ extension of the Highbay, but at Level 69, 5' above the Highbay floor on Level 64. It provides an additional 10,000 (ISO 7) clean area for processing or payload encapsulation.

Primary use of the Transfer Tower Area is for removal of payloads greater than 25’ high (too large for the Transporter Airlock door).

The lower Tower Area is serviced by two cranes:

  1. 1. The Highbay 75-ton crane used to move payloads from the Cells or Highbay to the Lower Tower Area

  2. 2. The Upper Tower Area 30-ton crane used to lift payloads from the Lower Tower Area up to the Upper Tower area and then out the Main Doors to be lowered to an awaiting transporter on the SLC-6 Pad Deck
