Kulo nyaka, izindawo eziningi ezweni lethu beziyizimvula, manje sidinga ukwenza umsebenzi omuhle ukuvimbela ukugqwalaibhulokhi ye-lever yebhulokhi. Ibhulokhi lever lingasetshenziswa ezikhathini eziningi, kepha kuyadingeka ukugwema ukusebenzisa i-ibhulokhi ye-lever yebhulokhi esimweni sezulu esinemvula ukwenza ngcono impilo yensizakalo yebhulokhi ye-lever nokugcina ukusebenza kwe-block lever. Yenza umsebenzi wesondlo we-lever hoist esimweni sezulu esina. Izinto zeibhande le-lever 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 theibhande le-lever. 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.
