LLO LOS Installation Fixtures Review Support Beam Rolled on edge inside chamber as planned, but kept jamming as it was not centered within the chamber Suggestion: Additional side supporting rollers Lazy Susan (Shuttle) Worked fine, but had to be clamped down in place during LOS installation Suggestion: Adjustable set screws or clamps mounted on table
LLO LOS Installation Fixtures Review Lift Table Functional, but hard to crank with full load. A larger hand crank was installed. Double crank mechanism did not seem to cause any problem. Suggestion: Re-design Lift Table, Enclosed Hydraulic Jack w/ Expandable Bellow Tilt Table Over-constrained, got bent during LOS installation at LLO. Suggestion: Remove center ball with a hard-bolted spherical washer set, leave corners adjustable with set screws Additional photos here: http://www.ligo-la.caltech.edu/~ospjeld/fixtures/
