DANGER !
To avoid personal injury or death, before performing any static inspections,
make sure the platform carriage is fully lowered and the power has been
disconnected at the safety disconnect switch. Also, put signs at all gates,
doors, controls, etc. indicating that the system is out of service for
maintenance per OSHA Lock-Out, Tag-Out procedures.

1. Coat drive & lifting chains with oil; inspect for wear, rust, and bent or binding links
2. Inspect carriage guide rollers for wear, binding, or other indication of non-rotation
3. Inspect all gate/door interlocks and status switches for proper operation
4. Inspect all gates/doors for wear or damage

the pin holes in the adaptor piece
e. Chain Master Link or Repair Link – any damaged, slightly bent, or missing link
pins or pin retaining clips/cotter pins, or any damaged link plate, or any chain
