This information should be available in all machine rooms. See Figures 1-2, 1-3, and 1-4 for a
sample manufacturer's lubrication guide. Replacement. Replacement or repair of worn or defective components must be done in a
timely manner. By detecting and replacing worn components, it is often possible to prevent
elevator malfunctions and unscheduled shut downs. Most components are replaced because it is
more cost effective to do so. However, some parts must be repaired. These repairs must be
examined to assure the quality of the repair. The ANSI/ASME A17.1, Safety Code for Elevators
and Escalators specifically covers repairs and replacements of damaged, broken or worn parts on
equipment covered by the document. Depending on location, some parts must be replaced and
not repaired. Adjustments. Adjustments are an important part of good equipment maintenance. Proper
and timely adjustments keep the equipment working smoothly and quietly, thus assuring peak
performance and maximum life. Manufacturer's recommendations should be examined to
determine which components will possibly need periodic adjustments and the frequency at which
these adjustments should be made. Actual frequency should depend on the operating
environment and the amount of use of the equipment.
1.4.4 Maintenance Records
In addition to actual maintenance work, tasks performed should be recorded. A log for each
piece of equipment is required. It should be kept in the respective equipment area and should be
maintained by the individual responsible for serving the equipment. Supervisory staff should use
this record and other procedures to check the status of the preventive maintenance program.
These logs should indicate a schedule for tasks to be performed to ensure a maintenance program
designed for long life and proper and safe operation of all equipment. The log should also
contain a readable, sequential list of all problems encountered. This should include the exact
symptoms and corrective actions taken. This provides a job history which is needed to plot
continuous troubles. The log is also a great asset to other service mechanics who may be called
in to answer trouble calls when the regular maintenance man is not available. It is imperative
that all entries made by the service mechanic are legible, coherent and detailed enough so the
exact problems encountered and the corrective measures taken are used to build a job service
history file.
