Aluminum alloy ladder, the ladder must be run-in maintenance during the run-in period. When the machine is used during the specified run-in period, the Use the corresponding regulations, and check the lubrication and tightening conditions comprehensively, observe the condition of each part of the whole ladder, and solve the abnormality in time. The focus of running-in maintenance is to replace each part of the lubricant, lubricate each part, and tighten each bolt. After the running-in period ends Perform a secondary maintenance. Domestic stairs are used as components for inter-floor traffic in buildings.
It is composed of continuous steps, platforms and enclosure structures. Generally wood is mainly used, metal stairs can also be considered, but the foot feel is not as good as wooden stairs. Home staircase balustrades are divided into wood, stainless steel, iron and stone, among which wood is more comfortable. The foot of the bamboo ladder must be tied with rubber with concave and convex grooves (such as car tires) to increase its frictional resistance. Because the foot of the wooden ladder has a certain slope, it is necessary to keep the bottom surface of the foot parallel to the ground. Ladder should be placed as far away as possible from doors and windows, corners or passage openings. If you must work near the above-mentioned areas, roadblocks or warning signs should be set up nearby. Make sure that there is no heat source and moisture near the ladder.
No debris should be piled up under and around the aluminum alloy ladder. Ladder is useful when placing some high places in the home or installing some lamps. Most of the ladders used in our home are aluminum alloy ladders. Because aluminum alloy ladders are relatively light in weight and cheaper in price, they can be folded, which greatly increases the range of use of aluminum alloy ladders. The material, size and strength of the portable ladder (hereinafter referred to as the ladder) shall meet the relevant requirements of GB/T 17889.1-1999 and GB/T 17889.2-1999.
The length of the straight ladder should not exceed 6m, and the full extension length of the extension ladder should not exceed 11m, and should be equipped Limiting device to ensure that the extended part and the non-extended part overlap by at least 1m. The organization shall inspect the newly purchased ladders before putting them into use, and shall inspect them regularly and affix the inspection marks during the use periodknowledge. At the same time, the ladder should be inspected before each use to ensure that it is always in good condition.
Ladders with faulty aluminum alloy ladders should stop using them, put a "prohibited use" label, and repair them in time . The ladder should be placed stably when in use. When using a ladder on a smooth surface, you should take anti-slip measures such as end sleeves and tying anti-slip rubber. The angle between the straight ladder and the extension ladder and the ground is 60°～70. For straight ladders, extension ladders and herringbone ladders above 2.4m (including 2.4m), they should be fixed with ropes or held by a special person. When fixing or untie the ropes, a special person should escalate the ladder. Special insulated ladders should be used in the circuit control box, high-voltage power line, electric welding and other places where there is a risk of electric leakage. The use of metal ladders is strictly prohibited.
