Using the Chain Hoist
Prior to Operation
1.Support for the hoist may be hook, clevis pin, trolley, or beam clamp. Whatever method of suspension is chosen, the support components must be rated equal to, or greater than the capacity of the chain hoist.
2.If the chain hoist has not been used for an extended period of time, check for proper operation before putting into service.
3.The brake mechanism must be kept clean and free from dirt, water, and oil. Never allow oil to penetrate the brake mechanism. Always keep your chain hoist clean and store in a clean, dry location.
4.Although oiling the chain is not mandatory, a light coat of
5.Check the chain for damage and elongation. Replace damaged chain before using the chain hoist.
The load chain supplied with your JET chain hoist is designed, manufactured, and tested for proper fit and durability. Over a period of time, the chain may need to be replaced. For your own safety, use factory replacement chain only.
Use of other than factory replacement chain may cause serious injury and/or damage to the hoist.
6.The top and bottom hooks on your JET chain hoist are designed to open to warn of an overload. Both top and bottom hooks have three indicator points cast into the hook. See Figure 1. Measurements between all three indicator points should be the same. If they are not the same, the hook must be replaced.
7.It is important to check top and bottom hooks for proper opening. If the safety latch no longer contacts the hook opening, replace the hook.
Never side load the top or bottom hook; this practice is dangerous and could lead to serious injury.
8.If the vertical angle at the neck of the bottom or top hook reaches 10°, replace the hook (see Figure 2).
