These two days, the small partners in the north must have felt the severity of the cold wave.，At present, the main force of the cold wave is rapidly crossing the Huaihe River.、 The Yangtze River ，Most parts of the country are about to enter winter overnight.。

The vast number of hanging friends not only need to add their own clothes.，Pay attention to keeping warm，Hydraulic oil due to temperature drop、Diesel oil and lubricants become sticky.，It is easy to cause difficulties in starting the engine and abnormal wear due to poor lubrication of various mechanisms.，Therefore, for the healthy operation of the crane,，Also want to change on time to crane big baby.“Winter clothes”Yo！

 

Engine maintenance

The temperature is very low in winter.，Viscous wax of diesel oil will block the low pressure pipeline.，Or poor atomization；Diesel oil is sticky，Poor lubrication inside the engine，And even that rotation resistance is large.，Cause the engine to fail to reach the starting speed，Unable to start smoothly，In case of wax deposition of diesel oil，Change the fuel immediately.，At the same time, melt and clean waxed fuel oil in the low-pressure pipeline.。

Therefore, the correct selection of the appropriate grade of diesel and engine oil is the most important.，The following editor has prepared the applicable ambient temperature for each grade of diesel oil and diesel engine oil.，You can look at the correspondence.，What brand of diesel should be used for your equipment?、Engine oil。

Recommended Diesel Fuel for Engine(G252)

Engine oil recommendations

Notice：In addition to the mainframe，The power car attached to the crane should not forget to replace the appropriate grade of diesel and oil.。

 

Hydraulic and Lubrication System

In the cold northern region，Motive temperature may reach-35℃，In the wind field and other environments, the body temperature may reach-45℃，At this time, the fluidity of hydraulic oil is poor.，It will also cause the hydraulic system to run unsmoothly.，If the operation is too hasty，Risk of damage to hydraulic component fluid。We work according to different environments.，Use the appropriate hydraulic oil，At the same time, after the first start every day,，Allow the complete machine to preheat the hydraulic system for a period of time at low load。

Specification and application scope of hydraulic oil

Key parts of the whole vehicle, such as slewing bearing、Wire Rope，Pulley，Hooks, etc，Temperature drop is easy to causeLubricating greaseDry and hard，Lubrication failure or dry grinding，Service life of damaged bearing or wire rope，The winter grease should be replaced，Lithium Grease No.3 is recommended for winter use.。

The above recommended motivation maintenance supplies，Customers can contact the local service engineer of XCMG to purchase the original spare parts.，Replace your equipment“Winter clothes”，Put your crawler crane into service more efficiently and reliably this winter。
