Description: When the explosion-proof chain hoist is in use, it can only be lifted and cannot be lowered. What causes this? Let me explain to you.
When the explosion-proof chain hoist is in use, it can only be lifted and cannot be lowered. What causes this? Let me explain to you.
1. Excessive force during use will cause the card chain to be off-chain, which will cause it to be unable to drop during use. At this time, you can continue to use it only by resetting the chain.
2. The screws inside are too tight, so that the long shaft cannot be rotated flexibly and will not be able to fall, mainly loosening the screws.
3. When using too many stains, it will cause the stains to enter the gear and cause excessive resistance, which will cause the problem of difficult lifting. At this time, you only need to remove the stains. You must do cleaning after each use.
4. During the use of explosion-proof chain hoists, the friction force increases due to the decrease of lubricating oil, which will not be reduced. At this time, just add an appropriate amount of lubricating oil for lubrication.
5. The brake pads cannot be lowered if they are not separated. At this time, as long as the chain is pulled downwards with inertia, it can be pulled several times at a time. It feels that the chain can be used normally when it is rolled. The sprocket and gear can be separated by retrograde striking the brake pads.
