ZYS taper roller bearing crane maintenance operation 50 hours lubricated once

maintenance crane technology shift tooth surface work 10 once the debris should be removed and re- coated with grease.
 In order to ensure crane maintenance technical reliability of the bolt work to avoid bolt preload is insufficient, slewing the first 100 hours of work and 500 hours , respectively crane ZYS Precision Bearings maintenance should check pretension bolts . Then every 1000 hours of operation should be checked once pretension .
technology to connect maintenance crane slewing ring bolts and nuts are made of high-strength bolts and nuts ; double nuts and lock .
crane maintenance techniques tighten the nut should topcoat oil and nut threaded end of the bolt , and a torque wrench should be used uniformly in the circumferential direction ZYS taper roller bearings of symmetry repeatedly tightened. Crane Maintenance Technical finally tightened again when the crane maintenance techniques on each bolt tightening torque should be roughly uniform.
 crane maintenance technology in the slewing ring gear surface raceway parts are aligned cloth 4 cup oil , thereby adding grease to the Raceway . Under normal circumstances , slewing crane maintenance operation 50 hours lubricated once. Every crane maintenance techniques must add a little oil until the oil leaking from the seal so far .
