MAINTENANCE SCHEDULE
There are a number of factors which can affect the
design life including but not limited to, severity of
operating conditions/routine maintenance. Dependent
on the frequency of use and severity of the operating
environment, planned inspections shall be carried out
at a frequency to enable the aerial work platform to be
kept in a safe and satisfactory condition. Maintenance
operations must be carried out by a SINOBOOM-
approved qualified technician, and the maintenance
operations performed must be recorded in the
maintenance inspection report.
The table below is the Maintenance Schedule
recommended by SINOBOOM. The harsher the
operating environment, the more frequent the
inspection will be.
