The elevator will be suspended for one day. How to write the notice of replacing wire rope?

Notice: Dear users, after strict inspection, the broken wire and wear of elevator wire rope have reached the scrapping requirements of relevant national standards. For the safety of users riding the elevator, it is planned to replace the elevator wire rope on a certain day in a certain year, which takes about 8- 12 hours. During the replacement of wire rope, the elevator will stop running. Please be prepared from a certain point to a certain point, hoping to tell each other. I am deeply sorry for the inconvenience.

China ranks first in the world with an annual output of 6,543,800 tons of steel wire rope, and phosphating steel wire rope is a revolutionary innovation in the field of steel wire rope in the world.

1. Phosphating coated steel wire rope, after manganese or zinc-manganese phosphating treatment, the wear resistance, corrosion resistance and rust resistance of steel wire rope have all jumped. The compound action of phosphating film and grease can effectively inhibit fretting wear, and the fatigue life is about 3 times that of smooth steel wire rope with the same structure. Fatigue life can be verified by fatigue test (the fatigue test done by ourselves is the most reliable), which is an upgraded product of smooth steel wire rope and can also replace galvanized steel wire rope with thin zinc layer after plating.

2. Galvanized steel wire rope, hot dip galvanizing and electrogalvanizing.

3. Stainless steel wire rope, 304 or 3 16 stainless steel, has good anticorrosion effect but is expensive.

4. Plastic coated steel wire rope, based on which the outer layer is coated with polyethylene or polypropylene.

5. Smooth steel wire rope will be completely replaced by phosphating coated steel wire rope.

In atmospheric environment, manganese phosphating coated steel wire rope is preferred, and hot dip galvanized-phosphating double coated steel wire rope is preferred in heavy corrosive environment. Please note that the name and implementation standard of wire rope should be indicated on the purchase invoice, such as phosphating coated wire rope GB89 18-2006. Patent products should be painted with the patent number on the outer packaging of wire rope, so as to protect the rights in case of quality objection, which is for reference only.
