Am-bliadhna, tha mòran sgìrean den dùthaich againn air a bhith fliuch, agus a-nis feumaidh sinn obair mhath a dhèanamh gus casg a chuir air meirge airson nabloc luamhan làimhe. Faodar am bloc luamhan a chleachdadh iomadh uair, ach feumar a bhith a ’seachnadh a bhith a’ cleachdadh anbloc luamhan làimhe ann an aimsir fliuch gus beatha seirbheis a ’bhloc luamhan a leasachadh agus coileanadh cleachdaidh a’ bhloc luamhan a chumail suas. Dèan obair cumail suas airson inneal togail an luamhan ann an aimsir fliuch. Tha stuth anbloc luamhan 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 thebloc luamhan. 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.
