Theory of chain pulley hoist lifting:
Chain as the upgrade version of the crown block, fully inherited the advantages of the crown block, at the same time adopting reverse non-return brake speed reducer and the combination of the chain pulley block, symmetry secondary spur gear rotating structure, simple, durable and efficient.
Hand chain hoist operation notice:
1.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
2.When lifting, operator should stand with same plane with the hand chain wheel, then pull the hand chain with gentle power In case the hand chain jumpy and snap ring.
3.If has the phenomenon that can not pull, pls do not pull with yank power, at this time, you should check carefully.
4.For ratchet and pawl springs, should often check, in order to prevent the brake failure and weight falling
5.When lifting, can not use your hand to touch the lfting chain, otherwise it will lest hurt fingers
6.Pls do not over weight used.
Chain block maintenance methods:
1.After use chain block should be cleaned and coated with anti-rust oil, stored in a dry place.
2.Maintenance and repair organised who should be more familar with hoist to prevent the one who is not understand the priciple of the machine performance of free disassembly.
3.Chain hoist after cleaning maintenance, load test should be carried out to confirm working, reliable braking can be delivered.
4.The brake friction surfaces must be kept clean, brake parts should be regularly check, prevent brake failure occured in the matter since the fall phenomenon.
