What is the difference between manual chain hoist and chain hoist
The manual chain hoist is different from the chain hoist. The so-called chain hoist is also called fairy hoist, heavy weight, manual hoist is a hand-operated lifting machine that is simple to use and easy to carry, also known as "chain hoist" or "reverse chain". It is suitable for short-distance lifting and transportation of small equipment and cargo, and the lifting weight is generally not more than 10t. The chain hoist has the characteristics of compact structure and low hand pulling force. Are the chain hoist and chain hoist the same product? What is the difference between the two? The following editor will introduce the difference between the chain hoist and the chain hoist:
The manual chain hoist is used in this way. When the chain hoist hoist lifts a heavy object upwards, the manual chain and the hand chain wheel are pulled clockwise to rotate, the friction plate ratchet and the brake seat are pressed together to rotate together, and the long axis of the tooth rotates Plate gears, tooth short shafts and spline hole gears. In this way, the hoisting sprocket installed on the spline hole gear drives the hoisting chain, thereby smoothly lifting the weight. When descending, the hand zipper is pulled counterclockwise, the brake seat is separated from the brake pad, the ratchet wheel is stationary under the action of the pawl, and the five-tooth long shaft drives the lifting sprocket to run in the opposite direction, thereby smoothly dropping the weight. The chain hoist generally uses a ratchet friction plate type one-way brake, which can brake by itself under load. The pawl is engaged with the ratchet wheel under the action of the spring, and the brake works safely.
Check whether the upper and lower hooks are fixed before lifting the manual chain hoist. 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 pull the bracelet to rotate the bracelet in a clockwise direction to raise the weight; pull the bracelet in the opposite direction to slowly drop the weight.
When lifting heavy objects, it is strictly forbidden for people to do any work or walk under the heavy objects, so as to avoid personal accidents, and overloading the hand chain hoist is strictly prohibited.
The difference between the manual chain hoist and chain hoist has been introduced above. I believe you have seen the difference between the two devices so that you can choose the one that suits you.
