連續陰雨，手排擋桿需做好防銹工作

This year, many areas of our country have been rainy, and now we need to do a good job of preventing rust for the manual lever block. The lever block can be used in many occasions, but it is necessary to avoid using the manual lever block in rainy weather to improve the service life of the lever block and maintain the use performance of the lever block. Do maintenance work for the lever hoist in rainy weather. The material of the lever block is metal, and most of the metal has the defect of rust. Doing good maintenance work can avoid the danger of rusting on the lever hoist and extend the lever block. The service life improves its operational safety. If the project is more urgent and the amount of precipitation is particularly low, people can consider building a canopy for lifting work, but it must be maintained in time after use.
