Second, the purchase suggestion
1, if you need to use a ladder, you must choose a suitable ladder. Ladders are basically divided into two types, one is a straight ladder and the other is a movable ladder. The vertical ladder can't stand alone, but must lean against a fixed object. The American Occupational Safety and Health Administration stipulates that the length of the top of a vertical ladder must be more than 965,438+0 cm above the horizontal plane to be reached (special attention: feet for a 3-foot ladder), which is usually called overstretching. The main purpose of overstretching is to make the center of gravity of the straight ladder close to the fixed object, so that the ladder is not easy to fall over when people get up and down. However, if the straight ladder can't meet the leapfrog requirements, the top of the ladder must be fixed, and a grasping device or handrail must be installed on the ladder to provide three-point contact (that is, two feet and one hand) for people to get up and down the ladder.
There are ladders made of metal, wood and fiberglass in the market. What kind of ladder should I use? Although many people know that metal ladders cannot be used in places where there is a danger of electric shock, many people in the United States are electrocuted every year because metal ladders fall on bare wires. However, it should be noted that even wooden ladders and glass fiber reinforced plastic ladders may be electrocuted under wet conditions. Although the glass fiber ladder has the advantages of high strength and light weight, the glass fiber material is easily deteriorated by sunlight, and other chemicals are also easy to damage the glass fiber. Therefore, when using the glass fiber ladder, it is necessary to check the damaged features, such as discoloration or cracking. Wooden ladders are heavier than aluminum ladders, which are easy to age and damage.
3. When choosing a ladder, you should pay attention to its maximum load limit. Overweight people or people carrying overweight items should pay special attention when going up and down the ladder. According to the ladder load, the United States is divided into four grades: light, medium, heavy and super heavy. The maximum load capacity is 965,438+0 kg (200 lbs), 65,438+002 kg (225 lbs) and 65,438+08 respectively. (At present, there is no such specification in China)
