MAINTENANCE EVALUATION CHECKLIST ELECTRIC ELEVATORS

Transcription

1 Manufacturer: Model: Evaluation Performed By: INTRODUCTION: This checklist will enable the user to make an objective appraisal of the condition of the equipment. Given the variety and complexity of the equipment, many of the questions may not apply. When completing this form, rate each of the items using one of the three columns provided. Enter N/A in those columns that do not apply to the installation being evaluated. NOTE: The following items correlate to the NEII Maintenance Guidelines. The number in the Paragraph column corresponds with the Paragraph number in the Maintenance Guidelines.
