The winter maintenance of construction machinery is of great significance. Especially in the northern regions where winters are long and the temperature remains low for extended periods. When construction machinery is used in winter, the cold climate can easily lead to difficulties in starting internal combustion engines, freezing of cooling water and electrolyte, intensified wear […]

The reasons for the downward deflection of the main girder of overhead cranes are multifaceted and should be analyzed according to specific circumstances. Generally speaking, issues can arise from design, manufacturing, transportation, rakibidda, and use. (1) The Impact of Unreasonable DesignIn the past, China followed the Soviet standards. The static stiffness of the main girder […]

Regardless of the type of machinery, different lubricating oils are prohibited from being mixed for use, and reducers are no exception. For reducers, the positions of the oil level plug, drain plug, and breather are determined by their installation locations. When it comes to the use, kormeerid, and maintenance of the lubricating oil in reducers, […]

Rakibaadda wadooyinka wiishashka waa geedi socod muhiim ah oo hubinaya isku toosinta saxda ah iyo hawlgalka wiishashyada sare. Tallaabooyinka faahfaahsan ee soo socda ayaa muujinaya habka rakibidda: 1. Calaamadaynta khadka Isticmaalka dhidibka meelaynta giraanta wiishka tixraac ahaan, geeyaan theodolite si loo dhiso dhibcaha gundhigga. Meel fog 60mm u jirta khadka dhexe ee wadada, […]

Hordhac Gelintu waa arrin lagama maarmaan u ah badbaadada wiishka, hubinta ilaalinta shaqaalaha iyo qalabka labadaba khatarta korontada. Dejinta saxda ah waxay yaraynaysaa halista shoogga korontada, dab, iyo waxyeellada qalabka iyadoo la siinayo waddo la isku halayn karo oo qulqulka korantada ay si ammaan ah ugu qulqulayaan dhulka. Hagahan waxa uu bixinayaa dulmar guud oo ku saabsan shuruudaha dhulka […]

I. Ishaarooyinka Midaysan ee Hawl-wadeenada iyo Shaqsiyaadka Calaamadaha Hawl-wadeennada wiishka Gantry iyo shaqaalaha ishaaradu waa inay adeegsadaan calaamado midaysan oo midaysan si loo xaqiijiyo xidhiidh iyo isku-dubarid wax ku ool ah.. Hawl-wadeenadu waa inay koraan ama soo dajiyaan qolka kantaroolka iyagoo isticmaalaya jaranjaro loo qoondeeyay. Kahor intaadan ku mashquulin korontada, kantaroolaha waa in loo rogaa booska dhexdhexaadka ah. Dabaqa qolku waa inuu […]
