The elevator daily maintenance unit shall, in accordance with the requirements of the elevator use and maintenance manual, formulate a daily maintenance plan, make daily maintenance records, and ensure the safety and technical performance of the elevator.

The daily maintenance of the elevator includes the following:

1) Clean, lubricate, adjust and inspect the elevator and safety facilities at least once every 15 days;

2) Inspect the appearance and operation of safety devices, wire ropes, brakes, contactors and other running parts at least once a month;

3) Conduct a safety test on safety devices, speed limiters and buffers every six months;

4) Conduct a braking ability test of mechanical brakes once a year;

5) Conduct a comprehensive inspection of the elevator operation condition at least once a year.

The legal analysis is as follows.

1. The user shall be responsible for thoroughly inspecting the ladder before using it. If problems are found, it is strictly forbidden to use.

2. The operation ladder should be placed on the ground or other supports, and should not be erected on unstable objects such as boxes, barrels, flat cars, etc., and should not be used as high, so as to prevent uneven sinking or loosening between the ladder feet and the cushion after being loaded, resulting in danger.

3. The working angle of the ladder is 75 ° ± 5 ° and the observation is appropriate, and it is easy to slip if it is too large, which is dangerous. Fixed ladders (herringbone ladders) and double ladders (high stools) should have strong and flexible dumpling chains, and the lower end should be equipped with a zipper that limits the opening angle. The spacing between the top and bottom of the ladder pedal should be 300mm, and there should be no missing gear.

4. The ladder should not be placed in the passage in front of the door; If the operation ladder is used at the passage, a special person should be set up to supervise or set up a temporary fence.

5. The bottom of the ladder foot should be firm, and anti-slip measures such as bandaging, nailing rubber, anchoring or clamping should be taken to prevent slipping and falling. Anti-slip measures should be taken on slippery and frozen ground.

6. Personnel should face the ladder when going up and down the ladder.

The elevator to be put into use after installation, overhaul or transformation shall be inspected in accordance with the provisions of the acceptance inspection in accordance with these regulations; The elevator in use shall be inspected once a year in accordance with the content of the regular inspection provisions of this regulation.

In case of natural disasters that may affect its safety technical performance or elevators after equipment accidents, as well as elevators that have been out of use for more than one year and are used again, after the equipment is overhauled, they shall be inspected in accordance with the requirements of the acceptance inspection.

By taking appropriate measures to reduce vibration and absorb sound insulation and reduce noise, and reduce and block the influence of low-frequency vibration of the elevator through the decreasing design, the indoor elevator noise level value of the elevator can be made below 35dB.

Legal analysis: The elevator is regularly inspected once a year, and the user must report to the special equipment inspection institute for inspection one month before the date of issuance of the inspection certificate of the previous year to determine the specific inspection date.

legal basis; Regulations on the Safety Supervision of Special Equipment》 Article 28 The user of special equipment shall, in accordance with the regular inspection requirements of the safety technical specifications, submit regular inspection requirements to the special equipment inspection and testing institution one month before the expiration of the validity period of the safety inspection.
