(3)Quality gears
20CrMnTi gears with high frequency carburization and 45-55HRC.
(4)Quenching And Refining G80 Chain
Medium frequency quenching heat treatment, low wear, anti-corrosion, selected lifting chain, test load is durable and safe.
Hand chain hoist operation notice:
pls check the lifting hook if it is firmed and Check whether there is any wrong twist on lifting chain link in order to avoid lifting chain is stuck

MATTERS NEEDING ATTENTION :
Chain block with the advantages of safe, easy maintenance, high efficiency , small pull ,light weight , portable , beautiful appearance , durable etc for the work of lifting , traction , decending and adjusting etc.
1.overload is prohibited strictly . It is forbidden to use other motivation than manpower operation
2.You must confirme the machine parts is in perfect condition , the transmission part and the lfiting chain is in good lubricity and iding conditions are normal
3.You need check the up-down hook is hooked firmly before lifting operation , lifting chain should be hanged vertically ,no wrong link , the double line chain hook rack don’t reverse
