9 Frequently Asked Questions About Chain Hoists

Chain hoists, also known as inverted chains or hanging chains, are a kind of lifting machinery used in conjunction with three wooden frames or herringbone frames. Its lifting capacity is between 0.5-20 tons, and there are eight kinds of lifting capacity: 0.5, 1.0, 1.5, 2.0, 3.0, 5.0, 10 and 20 tons. The lifting height depends on the length of the chain and the height of the gable, generally within 5 meters.
 

In addition, the chain block can also be used to tighten the wind rope of the pole cable and the rope of the bundled component during component transportation.
 

 

Common problems with chain hoists are:

 

How should chain hoists be marked and placed?

 

Those that pass the point inspection and those that fail the spot inspection shall be stored in different areas with obvious area marks.

 

Why do you not use too much force to operate the small chain of the chain hoist?

 

When operating the hand chain hoist, the strength of the zipper should be uniform, the speed should be moderate, and it should not be too strong, so as to prevent the hand zipper from falling out of the slot and jamming.

 

 

Why is the direction of the zipper consistent with the direction of the sprocket when operating a chain hoist?

 

Regardless of operating the chain hoist in any direction, the direction of the zipper must be consistent with the direction of the sprocket to prevent the hand chain from falling out of the groove.

 

Why can't the number of people be increased at will when the chain hoist can't be pulled?

 

When the hand chain hoist cannot be pulled, the reason should be found out, and the number of people should not be increased at will to prevent accidents caused by overloading.

 

Why should the chain hoist be tied to the lifting chain when the chain hoist is hoisted and stopped?

 

If the chain hoist in the process of lifting stays for a long time, the hand chain should be tied to the lifting face to prevent the self-locking failure and heavy objects from falling.

 

 

Why must a good chain hoist be used when lifting large parts?

 

If the chain hoist fails, it will cause personal injury.

 

Why should there be no less than two people when lifting a large piece with a chain hoist?

 

Prevent twisted chains or mishandling of large pieces from loss of control.

 

What is a chain hoist?

 

5 ton Chain hoists are also called hoisting and reversing chains. There are two types of manual and electric. It is a lifting tool used by electricians to lift various equipment and components, such as lifting or lowering distribution transformer equipment.

 

 

What should be paid attention to when using chain hoists?

 

Before use, you should first check the appearance to see if the structure is complete, whether the rotating part is flexible, and whether there is an oil lamp in the oil-filled part. Prevent dry grinding, chain channeling and other undesirable phenomena during use.

 

The ropes, brackets and beams of the hook and chain should be absolutely stable and reliable. After hanging, first pull the hand chain back, let the chain fall loose, so that it can reach the required lifting distance, and then slowly pull the hand chain, Lift heavy objects.

 

When carrying and using the chain, do not throw it anywhere, so as to prevent other sundries in the pulverized coal machine from being forced to rotate in the bearing, which will affect the service life.

 

Inverted chains that have been used for more than 3 months need to be disassembled, inspected, cleaned, and oiled. For faults such as missing parts, malfunctions, and structural damage, they must be repaired before they can continue to be used.
