The hand chain block has obvious performance advantages, which is not only safe and reliable, but also simple to operate and can achieve high work efficiency. Under normal use conditions, the manual chain hoist has the advantages of small pull force, lighter weight and portability, beautiful appearance, small size, and long durability, so it has been widely used in factories, mines, construction sites, docks, docks, etc. Warehouse and other occasions.
The use of hand chain block can bring a lot of convenience to the safe operation of the machine and the lifting of the goods, especially for the open air and no power supply operation. As a user, we should ensure good habits in daily operations so that we can fully play its role and value. Then, what issues should be paid attention to in the operation?
First of all, during the use of hand chain hoists, it must be consistent with its application standards, not overloaded with diagonally. At the same time, it must not operate with other power than manpower. Secondly, before using, the staff should carefully confirm that all components are intact, especially the transmission part and the lifting chain should be kept well-lubricated, and confirm that the idle condition is normal.
Third, before the formal operation, it is necessary to check and confirm that the hook is firm and reliable, and the lifting chain of the hand chain block should be hung vertically, and there should be no wrong twisted link, and the lower hook rack of the double row chain must not be turned over. In operation, the worker should stand in the same plane as the sprocket wheel to move the bracelet so that the sprocket wheel rotates in a clockwise direction to raise the weight. In the reverse direction, the heavy chain can be lowered.
Fourth, during the process of lifting the goods, no personnel can walk or perform operations under heavy objects to prevent major accidents. During the hoisting process of the manual chain hoist, regardless of whether the heavy object rises or falls, the force should be even and gentle when the manual chain is shaken. Do not use too much force to avoid the bracelet chain jumping or snap ring. Remember that when the heavy object lands safely and firmly, remove the manual chain hoist hook.
