    Operation principle and internal analysis of stainless steel chain hoist


Description: Stainless steel chain hoist is a lifting tool that can be used without power. The principle of use is also what we have always wanted to understand. Why a small chain hoist can lift dozens of times heavier than him Items? Let's take a look at the internal decomposition of the chain hoist principle.

Stainless steel chain hoist is a lifting tool that can be used without power. The principle of its use is also what we have always wanted to understand. Why a small chain hoist can lift items that are dozens of times heavier than him ? Let's take a look at the internal decomposition of the chain hoist principle.

Principle of stainless steel chain hoist:

The operator operates the hand zipper bar to drive the driving pinion gear to rotate, and the pinion gear drives the large gear to rotate, so that the torque output can be amplified, thereby lifting the heavy object. There is a ratchet and pawl mechanism on the inside of the hand zipper strip, so that the sprocket can only rotate in one direction, and it can also play the role of immediate braking.

Internal decomposition of stainless steel chain hoist:

Lifting decomposition. The operator stands on one side of the hand chain wheel and pulls down the hand zipper bar to rotate the hand chain wheel clockwise. Therefore, the hand chain wheel is driven by each transmission gear to rotate the hoist chain wheel, and the animal chain is lifted by the hoist chain. If stopped in the air, the ratchet and pawl can act as a brake.

Falling down. Pull down the other hand zipper bar to rotate the bracelet wheel counterclockwise. At this time, the pawl releases the ratchet wheel, and it will drop steadily under the weight of the item. When the bracelet stops pulling, the brake immediately resumes the braking function, and the ratchet is directly caught by the ratchet, so that the article can be stopped directly in the air.

The above is the operation principle of stainless steel chain hoist introduced by the stainless steel chain hoist manufacturer and the internal analysis of the chain hoist. I hope it will be helpful to you. If necessary, please feel free to 开心十三张!
