Preventive Maintenance Intervals for Transit Buses: A Synthesis of Transit Practice. Transit Cooperative Research Program (TCRP) Synthesis 81

摘要

The objective of every maintenance department is to anticipate repairs and initiate activities that prevent mechanical failures. Transit agencies perform various preventive maintenance (PM) activities at specified intervals to achieve this objective. Some intervals evolve from manufacturers specifications and agency experiences; others are simply handed down over time with no real understanding of where they came from. This study examines preventive measures taken by a sampling of transit agencies to ensure buses are on time, protect taxpayer investments, and promote passenger satisfaction and public safety. Effective PM also ensures that buses reach useful service life as defined by the FTA.
