Learn Everything about Manual Chain Pulley and its Applications

Lifting heavy objects has severe consequences if you do them without a machine. Even a simple machine like a manual chain pulley can prevent many problems and increase productivity at a better rate. If you want to boost your work performance with minimum effort, you need to know everything about a manual chain pulley. Since it has been in the industry for a long time, there are more advanced types available in the market. But if you are looking for a cost-effective option, this one is going to do a lot for you. First of all, you need to know about these pulleys and then start searching for a top chain pulley provider to improve your productivity.

Hand chain hoist, chain pulley block, and manual chain hoist are some common names for this pulley. If you start looking for it online, make sure you know about its common terms. Before you know how it works and what its applications are, you need to know something about its components to understand it better. The reason is that each component’s size and endurance level have a huge impact on productivity.

Components in a Manual Chain Pulley

A manual chain pulley is composed of some crucial components. These components coordinate with the help of manual input, which a user gives to it. Just a little effort from one side makes this machine lift heavy objects weighing tons.

• 2 swivel hooks (upper hook and lower hook)
• Double pawl braking system
• 2 chains (load chain and hand chain)
• Hoist body

If we describe these components, these swivel hooks are usually made up of alloy steel. These hooks have the tendency to endure tons of weight imposed on them. Besides, both chains have different thicknesses and sizes since they have different motions. Likewise, both chains are made up of alloy steel. Moreover, a hand chain has a galvanized coating and the load chain has a black oxidized coating. Besides, anti-loosening screws help it remain stable, which is also a great feature.

How Does a Manual Chain Pulley Work?

Its process is simple if you look at its working. Since two swivel hooks are in it, the upper swivel hook is for hanging the pulley and the lower one is for lifting the weight. Likewise, the hand chain is for controlling the pulley’s movement and the load chain is for lifting the weight. All of these components depend upon the hoist body, which holds all of them together.

When a user pulls the hand chain, the load chain starts pulling the weight on it. As soon as the user stops pulling the hand chain, the load chain also stops at the same speed. It happens due to a double pawl braking system in a manual chain pulley. This braking system prevents the chain from dropping the object because of sudden stoppage of motion. As a result, this brake prevents this pulley from any kind of accident.

What is the Weight Capacity Range of a Manual Chain Pulley?

Now let’s see how much weight can a manual pulley lift. Its working load limit ranges between 0.5 and 50 tons. However, people usually use a manual pulley to handle objects weighing around 0.5 and 2 tons. But in some cases, this weight can go above 10 tons depending on the kind of task one requires. To illustrate, it goes with weights like 0.5, 1, 5, 10, 20, 30, 40, and 50 tons.

What is the Average Chain Length of a Manual Chain Pulley?

Since these pulleys have multiple applications, their chain lengths also vary. Different objects have different requirements for lifting, which calls for a need for different sizes of chains. To illustrate, these chains are 10 ft (3 m), 15 ft (4.6 m), 20 ft (6 m), 30 ft (9.1 m), and 40 ft (12.2 m) long. In some cases, these lengths further extend. Also, it helps to have better access to lifting any object because a shorter length of the chain might prevent you from pulling larger objects in some cases.

Chain Pulleys Applications

A manual chain pulley is very common in commercial uses because it makes it quite simple to lift any heavy object. Whether you need to lift a car’s engine or even a whole wooden box filled with heavy stuff, these chain pulleys are very useful.

Warehouse

You will usually see them in warehouses while lifting various objects. Due to this manual chain pulley, laborers don’t need automatic machinery for heavy lifting. Workers lift heavy pallets for various uses with the help of this simple machine. They also use it for manual weighing purposes in different industries.

Construction

Here is another common place where you can see these manual pulleys’ usage. For lifting heavy metals like steel bars or even large rubbles at construction, these hand chain pulleys are really useful. It is also safe as it has efficient brakes to avoid any injury at the workplace. Moreover, these pulleys are cheaper than other automatic machines for simple tasks.

Factories

Whether you need to lift raw materials or finished products, a manual chain pulley can be really handy for you. With the help of it, laborers do not have to rely upon advanced-electric machines. Likewise, it is cost-effective and efficient for higher productivity at factories.

Workshops

Likewise, they are really helpful at workshops. Mechanics don’t need to hurt their backs because this simple pulley makes it easy to lift heavy objects like engines, wheels, frames, etc. It also prevents any injury because its alloy chains can withstand tons of weight comfortably. Make sure you use the right size of manual pulley because each size has its endurance limit.

Conclusion

Hopefully, you have learned enough about manual chain pulleys here. With the help of it, you will be able to buy some without any confusion. Since there are differences in metal type, chain size, workload limit, and size, you need to be aware of your working conditions. Each pulley has a different level of resistance to cope with the load limit.
