How to avoid committing card chain blocks

In the course of  chainb lock ，  hand chain made cards are the most common problems occur today simply from the following aspects to avoid committing card chainb locks to ensure that the  hoist equipment  life and efficiency:
1, chainb locks friction plate, it should be in frequent use seven days for a check, if found friction plate with oil, should be immediately replaced, if found should immediately replace the friction plate is thin, because of the emergence both of these problems can cause skidding  manual hoist s
2, manual hoists routine inspection, the corresponding mechanical parts for routine maintenance, to see if mechanical parts based on the appearance of rust, if the above please apply lubricant
3, chain hoists chain should always use lubricant maintenance, one is causing the card to prevent the chain rusty chain, and second is to extend the life of the chain.
4, chain hoist brake pads under a ratchet, ratchet pawl next one, such as the pawl spring loose will cause manual hoists without brakes.
5, hand chain guide wheel, to have regular checks to see whether there is squeezing the guide wheel, deformation of the situation, such as the following problems should immediately check the chain, whether the size of deformation, the phenomenon of broken teeth if the problem should be immediately replacement parts
The above mentioned chain hoist maintenance, routine inspection, maintenance, are relatively simple and do not need special tools to assist the operator can independently, manual hoists should be familiar with the product before use instructions for use.
