I. Operational principles for maintenance
Cleaning, lubricants, inspection, repair, adjustment。
2. In our daily maintenance of elevators, the following security matters must be noted:
1. Proficiency in safety operating procedures and operation in accordance with safety operating procedures。
2. Safety assessment, risk scanning for pre-working field operations。
3. Always under the operational mode of overhaul。
4. Proper use of personal protective gear。
5. Proper use of equipped tools。
Maintenance operations
1. Maintenance operations are performed in accordance with the monthly, quarterly and annual maintenance plans, and the following items are the focus of work。
2. All safety protection switch parts for elevators, room parts and environment, sedan parts and environmental wellway parts and environmental, pit parts and environmental cleaning. Axes of all active chain components, lubrication of linked institutions of mechanically connected components。
3. Equipment-set refuelling holes must be regularly refuelled by machine lubricating oil tables that meet the requirements。
4. An examination of the degree of wear and tear of the hold pads by the extraction mechanism, which is effective。
5. Buffers are fixed, hydraulic oil levels of hydraulic buffers are checked, and buffers are operated with electrical connection switches。
6. All inspections and adjustments shall be performed in a state of control of the elevator, or when the elevator ceases to operate。
7. It is possible to do everything possible not to disconnect the power of the elevator when it does not require power outage, so as not to turn off the plugs after the elevator has broken, the high voltage shock burns the pressure-sensitive elements on the circuit board, or the destruction of ageing resistance elements on the electronic version (there are cases in which the project burned the frequency transformer at the time of the power outage, and the computer storage system of the elevator control system data were lost, when the malfunctioning owner of the operation did not accept the account, which we, the maintainer, must avoid)。
8. When the elevator is called by the owner of the broken elevator, we can conduct a blackout of the elevator, at which point we can also conduct a full medical examination of all the mechanical parts of the electrical parts of the elevator. (the operational generator at this time is destroyed, the failure is lost, the owner is completely acceptable)
9. Adjustment and replacement of damaged and ageing components in the event of power outages in elevator equipment, which must be equipped with an automatic stratospheric rescue opener, and the equipment must be disconnected and configured to confirm the elevator equipment and the lack of energy in the control cabinet. Check the loose connection of electrical parts, confirm that the connection is reliable, that the equipment generated at this time is ageing and damaged, and that the failure of the electrical shock is completely acceptable to the owner。
10. Rotation of all components, no abnormal sound of device action
11. The conditions in which elevators operate are unique, and the reasons for their recurrence must be identified。
12. An elevator is used to observe that there is no abnormal vibration in the quality of the operation of the elevator and that comfort is in line with product design requirements。
Paperless uploading of work records, (cleaning), maintenance records and customer confirmation。
V. Avoiding paperless uploading of work records only and non-operational (sweeping) access to the site。
