One step: Before using the gourd in hand, carefully check it to check whether the hooks, chains and shafts are deformed or damaged, whether the sales of the section of the chain are firm and reliable, whether the transmission part is flexible, whether the braking part is reliable, the hand hand, the hand hand Whether the zipper has a slide chain and hanging chain.

Step two: The hanging hanging of the gourd must be reliable, check whether the heavy chain is twisted, and it should be used after adjustment.

Three steps: When operating the hand to stract the gourd, first pull the bracelet and relax the lifting chain, so that it has a sufficient uplifting distance, and then slowly rise. After the chain is tightened, check whether each part is abnormal. Whether the hook is appropriate, confirm that it is normal, you can continue to work.

Four steps: Do not drag the zipper diagonally, do not excessively force. When using it or horizontally, the zipper direction should be consistent with the direction of the sprocket to avoid the occurrence of the card chain and the chain.

Five steps: The number of zippers should be determined based on the ability of the gourd. When you can't move, you should check whether it is overloaded, whether it is linked, or whether the gourd is damaged.

Step in six: In the process of hanging heavy objects, if the heavy object stays in the air for a long time, the zipper should be tied to the heavy object or the lifting chain to prevent the time from being too long and the machine locks itself. Accident.

Step of seven: Gourds must not be used overloaded. When several gourds are hung up at the same time, the force is balanced. There must be a person with a special person to conduct, the ups and downs synchronization.

Eight steps: Gourd should be maintained regularly, and rotating parts should be lubricated in time to reduce wear and prevent the chain from rusting. For severe rust, broken marks and cracks, it is not allowed to use it for scrap or update. Be careful not to seep the lubricating oil on the rubber piece to prevent self -locking from failing.

Step 9: Maintenance and maintenance should be carried out by those who are familiar with the gourd mechanism to prevent those who do not understand the principle of performance of the machine.
