Is the tonnage of the aluminum hand that is better, the better? In fact, the aluminum alloy hand holds the gourd with aluminum alloy cover. It should not only be mild, but also the self -weight of the aluminum alloy cover. We know that the aluminum alloy hand pulls gourds are mostly used in railway and electricity maintenance. Workers need to carry a hand -to -hand gourd to work in the high altitude. The lighter the tools, the more convenient the operation. The larger the specifications of the aluminum alloy hand, the greater the weight. For example, 0.75 tons of self -weight is about 4 kg, and 6 tons of self -weight are about 19 kg. In order to reduce the work pressure of workers, we cannot blindly choose large specifications, and choose the right specifications without overloading.
