How to maintain a chain hoist after being rained on

　　Hand chain hoists are often used in various outdoor environments such as construction sites and mines, which increases their frequency of use in the rain. Hand chain hoists need to be carefully maintained after being rained on, otherwise they are very prone to rusting and greatly reduce their service life. So what is the best way to handle it?

　　Rainwater is a combination of corrosive gases and other easily soluble substances in the air with water vapor. The main body of corrosive objects in the air is acidic, so rainwater itself is acidic. Once the chain hoist is exposed to rainwater for a long time, it will increase the possibility of chain hoist corrosion and cause rusting of chains and components.

　　The correct approach is to wipe and air dry the parts after being rained on (use a hair dryer and cold air to dry the parts). If the internal parts cannot be completely dried, the cover of the chain hoist can be disassembled and dried until it is completely dry. Secondly, anti rust grease or lubricating oil should be applied to the easily corroded parts.

　　After the above steps, a safety trial run should be carried out for the next use to ensure normal use. After normal treatment, the hand chain hoist has no significant impact, but it is still necessary to reduce the number of times the hand chain hoist is soaked in rain.

　　Tongue piece of chain hoist - safety barrier for lifting

　　The tongue is a very small and inconspicuous component on the hook of a chain hoist, but accidents caused by it are not uncommon.

　　The tongue of a chain hoist, also known as a safety tongue, safety card, or anti slip card, can only be seen frequently in places where a hook is used, such as wire rope electric hoists, ring chain electric hoists, and so on. Do not underestimate it, as its function is significant.

　　The tongue of the chain hoist can prevent the phenomenon of falling during the lifting process of heavy objects, increasing the safety of operation to a certain extent. The safety tongue is mainly installed at the opening of the hook, which can serve as a barrier and also provide protection.

　　The material of the tongue piece is generally made of cast steel, which has high strength. Generally, the component is in a closed state. When you want to lift or unload a heavy object, you need to pull it open to put or unload it.

　　When purchasing a chain hoist, a certificate of conformity is required, and the hook contains a safety buckle. Regular inspection and maintenance are also required during use to avoid accidents caused by heavy objects falling due to the chain hoist buckle.
