Passenger Elevator Machine Room Visual Inspection And Log
Daily visual inspection log for passenger elevator machine rooms. Covers controller cabinet, governor assembly, brake wear, oil level, drive sheave, and hoistway access. Designed for maintenance technicians and building reliability engineers to systematically record machine room conditions and preempt failures.
This log is used to perform a structured visual inspection of the passenger elevator machine room. It ensures that controller status, governor tension, brake gap & lining, oil level in the hydraulic reservoir (if applicable), drive sheave condition, and hoistway access are checked and documented every shift. Each item includes a pass/fail designation and space for actual readings. ASME A17.1 / CSA B44 compliance relies on daily documented inspections of machine room conditions.
- Lockout/Tagout — Verify that main line disconnect is locked out before opening any controller cabinet or governor cover. Use group LOTO if multiple technicians are present.
- Hard hat, safety glasses, hearing protection, and steel-toed boots required in machine room. Gloves required when handling oil dipstick or ropes.
- Required tools: flashlight, small flathead screwdriver (for governor seal), brake gap feeler gauge, oil dipstick or sight glass cloth, and this clipboard log.
- Confirm machine room door self-closes and latches properly. Emergency lighting must be functional. No storage of combustible materials in the room.
