How Does a Chain Block Work?
Chain block is a kind of manual hoisting machinery that is simple to use and easy to carry. It is also called inverted chain, chain hoist and other names. It is suitable for short-distance hoisting of small equipment. The lifting weight is up to 20 tons, and the lifting height is 3meters or 6 meters generally.
Chain block is very labor-saving and econimical. It can widely used in factories, miners, construction and other fields as installation machinery or hoisting equipment. The obvious advantage of block that is it can use in places where there is no power supply and narrow.
The chain block contains two wheels or cogs in which the chain is wrapped around. Both electric chain blocks and manual chain blocks have the same fundamental functions - when the hand chain is pulled, it wraps around the wheels which adds torque to the lifting mechanism, pulling the item that is on the other end of the load chain (usually with a strong bottom hook) and lifting it off the ground - the wheels inside the block are how they are able to lift heavy loads - even when operated manually.
Do not pull the hand chain diagonally when using.
Do not pull heavy objects diagonally and horizontally.
Do not lift loads over people when lifting or lowering.
