Proof chain hoists common problems

Proof chain hoists daily use will encounter some common problems such as: card chain, brake skid brake dead cars and other issues, the following tells you experience these common solution to the problem:
1 explosion-proof  chain block   routine maintenance checks are important and should be regularly corresponding mechanical parts for maintenance testing, look at whether there is rust all mechanical components, etc., should be promptly apply lubricant. Proof 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.

2, the proof  Manual hoist  friction plates should be regularly checked or replaced, it should be used frequently seven days to do an inspection, if found friction plate with oil, should be replaced immediately; if found thin linings should be replaced, because of the above two kind of problem will cause instability proof chain hoists brake skid.
3, proof chain hoists brakes under a ratchet, ratchet pawl next one, such as the pawl spring loose will cause chain hoists without brakes.
4, proof chain hoists load chain  guide wheels should be checked regularly to see if there is squeezing the guide wheel, deformation, broken teeth and other situation, such as found chains and size, etc. deformation, should immediately replace the corresponding proof chain hoists accessories.
