1.5 tons of aluminum alloy handle is 5 kg. Ordinary 1.5 tons of iron hand -tip gourd weight is 7 kg. Their standard chain length is 1.5 meters. Therefore, the self -weight of aluminum alloy hand holds the gourd is relatively light, suitable for high -altitude operations, easy to carry. And the aluminum alloy hand pulling the gourd body is not easy to rust aluminum alloy. It is necessary to comply with the rules and regulations of the use instructions and operations, so that the aluminum alloy hand -to -hand gourd can maintain a better working state, so as to improve the efficiency. It is the later maintenance of aluminum alloy hand -to -hand gourds, which can not only eliminate the safety hazards of the equipment in time and reduce the probability of failure in the operation, which can also improve the efficiency of the entire construction operation. The structure of hanging gourd must be firm and reliable. At work, the hooks, sales, chains, brakes and other component devices must be kept intact.
