Moving heavy loads from here to there requires lots of strength. For this reason, sometimes, you may not be able to carry a heavy thing on your own. At this point, you will think about getting a permanent solution to that problem. And, you will be glad to know, a chain hoist can help you move your weighty things quickly. But, how does a chain hoist work? That is what we will talk about today.
What Is A Chain Hoist?
A chain hoist, sometimes known as a chain block, is a lifting mechanism for heavy loads. When lifting or lowering heavy loads, this mechanism uses a chain wrapped around two wheels. If you pull the chain from one side, it will start to wind around the wheels and lift the attached heavy item on the other side. Generally, there is a hook on the opposite side of the chain, and any roped package using pieces of chains or ropes can be hung into that hook for lifting.
However, you can also attach the chain hoist to chain bags or lifting slings for better lifting. Because these components can take more load than other options. Actually, the chain bag is a full setup of a bag that can contain hefty items and attach to the hook.
On the other hand, a chain sling increases the ability to lift more weight when attaching to the hook after setting up with the heavy loads. In any case, a chain hoist does its job very well.
Parts of A Chain Hoist & Their Jobs
You already know that a chain hoist is a tool for lifting heavy materials using a chain. As this tool is used for lifting higher tons of weights, it must be made of a durable component. In like manner, the chain hoist is made of high-grade and durable steel, which ensures its high level of safety and reliability. However, the whole setup of the tool works using three parts: the chain, the lifting mechanism, and the hook.
Specifically, the chain has two loops or sides. After winding around the wheels, there will be one part of the chain on your hand, and another part will remain on the other side attached to the hook. The loop that stays on your hand is called the hand chain, and the other loop from the hook to the wheels is called the lifting chain.
When you pull the hand chain, the lifting chain will start to lift the heavy loads. Leaving the hand chain slowly in your hands will lower the loads using the lifting chain.
- Lifting Mechanism
This is the central part of a chain hoist. Because the lifting mechanism helps to create the lever for lifting weighty loads with minimal effort. Anyway, a lifting mechanism comprises the sprockets, gears, drive shaft, axle, cog, and wheels. All of these components help to create a lever for the lifting mechanism.
Sometimes, there is a brake or a chain stopper included in this part. This brake helps to control lowering or lifting the loads and reduces the possibility of sudden falls.
Different types of chain hooks are available in the market. The grab hook is permanently attached to the lifting chain. Typically, it is used to hook loads weighing a couple of tons. Though various methods are available for hooking the loads, the most popular methods are chain slings, load levelers, or attaching the load itself.
Another hook is located on the upper side lifting mechanism of the chain hoist. In simple terms, it is used to attach the lifting mechanism to the rooftop or housing. As a result, your chain hoist will be in a hanging position, and you are ready to lift any heavy load.
How A Whole Chain Hoist Setup Works
We have already mentioned the parts of the chain hoist and their working process. Let’s see how the whole setup works like a lifting machine.
If you ask about an electric chain hoist, it has nothing critical to control. You just need to attach the load with the grab hook and operate the lifting process properly using the right command on the operating machine. But, when you are using a manual chain hoist, all tasks are physically in your own hand. So, you need to control the whole setup perfectly for proper lifting.
Firstly, attach the grab hook with the load and make sure you lift a weight within the chain hoist’s highest limit. Then, check the lifting mechanism and wheels for any technical issues. If all is okay, pulling the hand chain will lift the load creating a lever on the lifting mechanism. Because the chain will get a tightened grip on the wheels and form a loop of a lever inside the mechanism for the pressurized tension of load.
Lastly, it is fair to say that the chain hoist is an excellent solution for lifting heavy loads. Furthermore, the mechanism of this tool is not difficult to understand after close examination, and anyone can do so. And for your better understanding, we have provided you with a complete overview of how a chain hoist works.
