Chain blockchain 1. It is under severe pressure to sew the overuse.
2. It is under the condition of using the power operation other than human.
3. Must confirm parts are intact before using, transmission parts and lifting chain lubrication is good, the idle condition is normal.
4. Check whether hook hanging up, up and down before hoisting chain should be vertical suspension, can not have wrong torsion link, under the double line chain rack may not reverse it.
5. The operator should stand in The same plane as The hand chain drag hand chain, make hand chain along The clockwise rotation, can make The weight happens; Start work reverse drag chain, the weight can Start slowly.
It is forbidden to people under the heavy work or make any action, in order to avoid a major accident.
In the process of lifting, regardless of the weight increase or decrease, drag force should be gentle, don't too hard, so as to avoid hand chain beating or snap ring.
8 The operator when hand pull is greater than The normal force is found, should immediately stop using it. To prevent The internal structure, To prevent falling objects.
To heavy security firm after landing, and then get laid hands on him under the chain hook.
After using, light with light, placed in a dry and ventilated places, the grease.
1. Diagonal pull overload is strictly prohibited.
2. Power operation other than manpower is strictly prohibited.

6. When lifting heavy objects, personnel are strictly forbidden to do any work or walk under the heavy objects to avoid serious accidents.
7. During the lifting process, no matter the weight rises or falls, the force should be uniform and gentle when you pull the chain.
8. If the operator finds that the tension of the hand is greater than the normal tension, it should stop using immediately. Prevent damage to the internal structure, in case of falling accident.
9. After the weight has landed safely, take the underarm of the hoist and lower the hook.
