Base the schedule on risk
Cycle count, vehicle type, environment, previous impacts, redundancy and the consequence of failure should determine the interval
A lightly used staff gate and a 24-hour logistics entrance should not receive the same maintenance plan
Track developing faults
Repeated call-outs are often symptoms of an unresolved mechanical problem, ageing cabling, water ingress, poor safety-device positioning or temporary modifications
Condition reports should separate immediate safety issues, planned repairs and long-term capital replacement so site managers can budget rather than react
Keep the complete entrance in scope
The gate motor is only one asset in the operating chain. Loop detectors, photocells, access control, maglocks, timers, interlocks and building signals must be tested in the modes the site actually uses
Maintenance records also help identify changes in fault pattern and equipment condition over time
Automatic gates and doors can cause serious injury. Keep clear of moving equipment and live electrical parts. If operation is unpredictable or unsafe, isolate the system where practical and arrange professional assessment
