How to maintain your ladder

Abstract: When we want to lift high things, but they are not high enough, household ladders are our common tools. As climbing equipment, the maintenance of household ladders is very important, so the placement of ladders should not be in danger of falling, nor should it be stored outdoors, but should be placed in a ventilated and dry place. The following is to introduce the maintenance knowledge of household ladders for you. How to maintain your ladder how to maintain your ladder?

1. Before using the ladder, routine visual inspection must be carried out. Ensure that the ladder structure is firm and reliable, and no dirt, grease or paint accumulates on it to prevent people from standing. When cracks, missing files or other defects that may affect safe use are found, they must be repaired before they can be put into use.

2. The bamboo ladder foot must be bound with rubber with concave and convex grooves (such as automobile tires) to increase its friction resistance. Because the foot of the wooden ladder has a certain inclination, it must be kept parallel to the ground.

3. When placing the ladder, please follow the principle of "four-point contact": ensure that the top ends of the two handrails of the ladder are firmly supported on a solid wall, and the two ladder legs must be firmly supported on a hard and horizontal foundation (don't put them on boxes or wooden blocks). If possible, fix the fulcrum of the ladder and be protected.

4. The ladder should be as far away from doors and windows, corners or entrances as possible. If it is necessary to work near the above areas, roadblocks or warning signs should be set up nearby. Make sure there is no heat and moisture near the ladder. Sundries shall not be piled under and around the ladder.

5. The working angle of the ladder should be 75 5, that is, the ratio of the distance between the foot and the vertical wall to the length of the ladder is 1: 4. The distance between the rungs (pedals) should be 30cm, and there should be no gap.

6. The standing height (working plane) should not exceed the third step down from the top of the ladder. Make sure that the top of the ladder is at least one meter higher than the highest point where you need to stand.

7. If site conditions permit, wrap the top of the ladder with foam pad or soft cloth, or fix the top of the ladder on the fulcrum with rope to prevent the ladder from sliding and protect the wall.

8. Work with a ladder of appropriate length. Don't connect two short ladders to one long ladder.

Before climbing the ladder, make sure that there are no knives, scissors or other sharp tools in your pocket.

10. Only one person is allowed to go up and down the ladder when working, and must face the ladder when going up and down, and no hand-held appliances are allowed. Appliances should be put in a satchel or fixed on a person. If the vessel is overweight, it should be lifted by appropriate methods.

1 1. Climbing a ladder always follows the principle of "three-point contact", that is, at least two hands and one foot or both feet and one hand must contact the ladder at the same time. Walk up and down slowly, climbing one rung (pedal) at a time.

12. When climbing a bamboo ladder, you must hold on to the rungs, not the handrails on both sides of the ladder, so as not to catch them when you slip.

13. When working on a ladder, you should keep your body center of gravity between the two handrails to achieve balance. Don't climb directly from one ladder to another.

14. Don't push or pull the scraper or other tools hard after keeping balance on the ladder.

15, when working on a ladder, be sure to wear rubber soles or other types of non-slip shoes.

16. When the operator feels dizzy on the ladder, he must inform the assistant below, hold the ladder with both hands, stand up straight, rest on the ladder for a while, and slowly climb down from the ladder.

Safety requirements for outdoor ladder operation

1, avoid working in gale or rain and snow weather above level 5.

2. The ladder must be placed on a solid and flat ground, and a splint should be laid at the foot of the ladder to ensure a safe foothold.

3. When the outdoor temperature is low in cold season, it is necessary to ensure that the ground does not freeze.

4. When the outdoor temperature is high in hot season, you must not work on the ladder for a long time, and you must rest properly to avoid heatstroke during work.

maintain

1, the ladder shall not be placed in danger of falling. When not in use, it must be placed horizontally to avoid dumping and injuring nearby personnel.

2. The ladder should not be stored outdoors, but should be placed in a ventilated and dry place.

3, found that there is a fracture, lack of files or other defects that may affect the safe use, must be repaired in time. If it cannot be repaired, it must be scrapped immediately.

4. Avoid repairing existing ladders or manufacturing new ladders in the work area, and do not temporarily repair ladders.

5. It must be noted that the safety performance of the repaired ladder may be weakened, so it is not appropriate to paint the ladder to prevent cracks or other damage problems on the surface of the ladder.
