Choose suitable ladders. Domestic ladders may not be strong enough for commercial or industrial use. When using a stepladder, it should be fully opened or locked and placed on a stable surface. When opening or closing the ladder, keep your hands away from the ladder hinge and the ladder lock clamp. Do not extend the body excessively, and place the stepladder directly in front of the work. Working sideways is the main cause of accidents, which can cause the body to overextend and cause the body to lose weight and fall.
If there is a workbench design on the stepladder, the workbench must be equipped with appropriate railings, and the standing point should not exceed Workbench. If the stepladder does not have a working design, the high standing point should be a pair of hands which can hold the ladder and maintain balance. Do not stand on the top of the stepladder or work on the top board with objects. Do not stand on a stepladder to move the ladder (walking), this is a very dangerous behavior. The stepladder cannot be used as a straight ladder.
Aluminum alloy ladders Some insulating ladders have high performance and some have low performance. What does the performance of an insulating ladder have to do with it? Material. The insulating ladder with good performance is mainly made of epoxy resin, which has strong toughness, wear resistance, corrosion resistance and long service life. Craftsmanship. The high-performance insulating ladder is manufactured by the polymerization pultrusion process, and the surface is plated with a protective layer, which is safe and reliable. maintain. If the insulation ladder is properly maintained, its performance can be greatly extended.
With the continuous development of the construction industry, the application rate of aluminum alloy profile series is increasing year by year. They are a kind of non-ferrous metal structural materials that are widely used in industry, and they have been widely used in aviation, aerospace, automobile, machinery manufacturing and other industries. Due to the particularity of the applied industry, they all have relatively high requirements for this type of material. So how to judge the quality of aluminum alloy profile series?
Although this is not absolute, you get what you pay for. In recent years, with the level of industry, the aluminum industry is becoming more and more popular, and sales are also diversified. Unknown customers will only choose industrial aluminum sales companies from low prices. This forces some companies that insist on quality first to ensure sales from lower raw materials and processing costs. The market chaos is becoming increasingly obvious. Therefore, it is more appropriate to distinguish according to the manufacturer.
