As an aluminum alloy hand, the gourd as a light and small lifting equipment, the volume and quality are relatively light. They are often used in outdoor or wild environment. The work efficiency is very high. In addition to its own mechanical properties, it is highly efficient. Operation and maintenance can also improve its efficiency. The first is to do the preliminary preparations of aluminum alloy hand -tip gourds, including inspection of the use of the venue, the inspection of the equipment, the operation training of the personnel, the fixing of heavy objects, etc. Comply with the rules and regulations of the use instructions and operations, so that the aluminum alloy hand holds the gourd can maintain a good working state, so as to improve the work efficiency; the third is the later maintenance of the aluminum alloy hand to pull the gourd, which can not only eliminate the safety of the equipment in time Hidden dangers, reducing the probability of failure in the operation, can also improve the efficiency of the entire construction operation.
