An inspection was performed on drive systems for the main storage vault by Dan McDonald, Travis Cave and Nadia Jorgenson. The functionality was not tested. Some areas for improvement noted, but otherwise nothing concerning was discovered. 

Notes:

• The wire insulation to the motor is showing wear and tear. Should be replaced in the future. For now was patched with electrical tape, see picture. May be beneficial to add an e-chain for the portion of the wiring that moves when door is opening and closing

• Emergency close mechanism cable should be changed to have a 5/32” Nico Sleeve

• Moving parts still need to be lubricated

• Chain inspected (OK)

• Gearbox inspected - OK

• All drive system set screws checked and tightened

• Sprocket alignment checked - OK

• Limit switches checked - OK

• Emergency close mechanism cable checked - OK
