30+inch+F3+Handling+Equipment

In order to handle the larger optics we have installed handling equipment in the roof of the fabrication area. This is an electric hoist. The mirrors weight around 55Kg and are risky to lift alone.

Also, there is a handling frame for lifting the optics into and out of the telescope test rig. Three strops are used to connect the frame to the hoist.

The mirror has 3 C shaped clips that are covered in 4 layers of heat shrink for protection to the glass surface. Folded tissue is also used for additional protection.
