Hand chain hoist is a commonly used lifting tool. The earliest hand chain hoist can be produced and processed from 0.25T-50 tons. The specifications can be up to 30 meters long. Because it does not require electricity and the price is much cheaper than electric products, so Loved by many households. At the same time, the hand chain hoist with larger tonnage can also lift large items, and at the same time, it can save more time and effort. When the electric hoist cannot be used, the hand hoist can fully demonstrate his advantages, so it is widely used in various places. Hand chain hoist use scope Hand chain hoist is also called Jinbuluo. Manual hoist is a kind of manual lifting machinery that is simple to use and easy to carry. It is also called "chain hoist" or "reverse chain". It is suitable for short-distance lifting of small equipment and goods, and the general lifting weight is generally not more than 10t. The hand chain hoist has the advantages of compact structure and small hand force. The safe use rules strictly prohibit overloading. Before use, make sure that the machine parts are intact, the transmission part and the lifting chain are well lubricated, and the idling condition is normal. Check whether the upper and lower hooks are hung firmly before lifting. Wrong operation such as hanging heavy objects on the tip is strictly prohibited. The lifting chain should be hung vertically without any twisted links, and the lower hook frame of the double-row chain must not be turned over. The operator should stand in the same plane as the bracelet and drag the bracelet to rotate the bracelet in a clockwise direction to raise the weight; drag the bracelet in the opposite direction and slowly descend at noon. When lifting heavy objects, personnel are strictly prohibited from doing any work or walking under the heavy objects to avoid personal accidents. During the lifting process, no matter the weight is rising or falling, when pulling the bracelet, the force should be even and gentle. Do not apply too much force to avoid the bracelet jumping or snapping. Hand chain hoist maintenance method After use, the hoist should be cleaned and coated with anti-rust grease and stored in a dry place. Maintenance and overhaul should be carried out by those who are more familiar with the hoist mechanism, to prevent those who do not understand the performance principle of this machine from disassembling and disassembling at will. After being cleaned and repaired, the hoist should be tested under no-load to confirm that it is working properly and the brake can be delivered only when it is reliable. The friction surface of the brake must be kept clean. The brake part should be checked frequently to prevent brake failure and self-falling phenomenon.
