近年来,铝合金梯子大量投放市场,受到了各行各业登高作业者的喜爱。它以坚固轻便,组合升降灵活,移动方便等特点而倍受欢迎。同样受到了电力行业使用者的重视,并进行了改进。在梯子的下支持点,装两个小轮子,使用时一头放在自行车的后衣架上,有小轮的一头放在地上,走起来相当轻巧,减少了肩扛的麻烦,可随之也带来了一个使用时的安全问题。 1、铝合金梯有它的优点,却也有它的缺点。铝合金是导电材料,作为电工作业登高安全用具绝缘性能差。若站在铝合金梯子上进行电气工作,触电危险性很大,光凭两头的橡皮是不能保证安全的。经常使用机械磨损使绝缘受到破坏且不易发现。特别是带有小轮的铝合金梯子,使用金属轮的,已毫无绝缘性能。不是金属轮的,经常放在地上磨擦,绝缘容易损坏。另外经与地面接触污垢严重,绝缘性能差,使用前不进行绝缘试验
In recent years, a large number of aluminum ladder on the market, by all walks of life ascending operators favorite. It is solid and lightweight, flexible combination movements, easy to move and so popular. Also by the power industry users attention, and made improvements. In the next support point of the ladder, equipped with two small wheels, the use of a bicycle on the rear of the hanger, a small wheel on the ground, walking quite lightweight, reducing the burden of shoulder, but also with A security issue came in for use. 1, aluminum ladder has its advantages, but it also has its shortcomings. Aluminum is a conductive material, as an electricalian climb safety appliances with poor insulation properties. If you stand on the aluminum ladder for electrical work, the risk of electric shock, with only two eraser can not be guaranteed. Frequent use of mechanical wear makes the insulation damaged and difficult to find. Especially with a small round aluminum ladder, the use of metal wheels, has no insulation properties. Not metal wheels, often on the ground friction, insulation is easy to damage. In addition, by the contact with the ground serious dirt, poor insulation, insulation test before use
