What Is a Chain Block

 

A chain block, or block and tackle, is a mechanical device for vertical lifting and lowering of heavy loads with ease. It's manually operated, making it ideal in locations where power isn't available. Its simplicity enables safe and easy single-person use, prioritising precision over speed in lifting operations.

 

Key Chain Block Components

 

Here's a breakdown of the essential parts of a chain block

Load chain

The chain that directly lifts and supports the weight of the load. Made of high-strength steel to handle heavy loads during lifting operations.

Hand chain

The chain used by the operator to control the lifting mechanism. Allows manual operation of the hoist by pulling to lift or lower the load.

Lifting hook

A robust hook at the end of the load chain for attaching to the load. Provides a secure connection point for various objects being lifted.

Main sprocket or load sprocket

Toothed wheel driving the load chain. Transfers power from the gearbox to the load chain, facilitating controlled lifting.

Pawl

Mechanical device engaging with the gears to prevent reverse movement. Ensures the load remains securely suspended by preventing chain slippage.

Gears

Mechanical components that transmit force and control the speed of lifting. Amplify the force applied to the chain, enabling controlled lifting operations.

Braking system

Mechanism to stop and hold the load at a desired position. Ensures safety by preventing accidental lowering and maintaining stability during lifting.

Gearbox casing

Enclosure housing the gears and other internal components. Protects the gears and ensures smooth operation by containing and lubricating moving parts.

Hand wheel

Component attached to the hand chain for manual control. Enables the user to control lifting and lowering operations with precision.

 

3 Main Differences Between Chain Block and Lever Hoist

 

Although these lifting devices have similar functions and appearances, they are operated differently.


Here are 3 differences between chain block and lever hoist:


● Chain block is used to lift and lower heavy loads vertically, while lever hoist is used to pull and lift in both vertically and horizontally or multi-directional positions.


● Lever hoist is operated using one hand by cranking the handle/ lever forward or backward. Chain blocks are operated with two hands by pulling down on the hand chain.


● Chain block gives you the ability to lift huge loads up to 50 tonnes with ease by using mechanical advantage. Its working load limit (WLL) is greater than a lever hoist which lifts a load up to 10,000 kg.


Chain blocks and lever hoists are excellent devices used for heavy-duty lifting and materials handling operations. A small pulling force will be turned to a larger force to handle heavy objects, thanks to the advanced lifting mechanism.


These manual hoists come with a compact design to fit in small spaces and allow ease of rigging. They can be easily managed by workers and are efficient to operate and serve their purpose efficiently. They are commonly used in construction, maintenance, and workspaces.
If your choice of a hoist is what is portable and does not require a power or electricity source, this is the one you are looking for. It is cost-efficient and easy to maintain. Most importantly, they are built with the highest quality material and are built to last.  

 

How Does a Manual Chain Block Work

 

A manual chain block comprises a lifting chain, hand chain and a holding hook. Most manual chain blocks function using electricity, however manual manual chain blocks can be applied too. The manual chain block pulley needs to be connected to the load through the grabbing hook.

 

Afterwards, when the hand chain is pulled, the chain stretches its grip on the wheel and creates a loop inside the tool causing a pressure that lifts the load from the ground.

What Is Hand Chain Pulley Block

 

A hand chain pulley block is a tool used to lift and lower heavy loads utilising a chain. Two wheels are functioning in it which the chain is wound around. When the chain is dragged, it winds around the wheels and starts to lift the item that is connected to the rope or chain via a hook. It can also be connected to lifting slings or chain bags to lift the load more smoothly.

Working Principle of Hand Chain Pulley Blocks

 

Hand chain pulley blocks work on a simple principle of lifting and transporting heavy loads. The load chain is attached to the lifting hook, which is then attached to the load. As the load chain is pulled, it rotates the pulley, which in turn, lifts the load.


The load is lifted in increments, with each rotation of the load chain. This allows the load to be lifted to the desired height. Once the load has been lifted to the desired height, the load chain can be lowered, and the load can be transported to its destination.

What Is the Purpose of Hand Chain Pulley Block
 

 

Chain pully blocks are often employed in garages because of their lifting capabilities, which allow them to quickly and efficiently remove engines from automobiles. Because a single person can control them, chain blocks are an incredibly efficient method to execute operations that would otherwise need more than two personnel.


Installation and maintenance of machinery may be done using chain block lifting equipment. They are also ideal for overhead work and small places. You can choose also an alternative of a chain pully block is electric chain hoist.


As well as on construction sites to hoist things from higher levels, chain blocks are used in assembly-line industries to move products onto and off conveyor belts. In addition, they are occasionally employed to winch vehicles out of dangerous terrain.


They are available in various capacities, making them appropriate for a diverse range of applications. Chain blocks with lifting capabilities of up to 25 tons are available. When it comes to transporting big objects, chain blocks are an excellent, low-cost alternative.


If you need the cost-effective chain block lifting machine for your business, you can select a chain block manufacturers. They use cutting-edge production procedures to provide the highest-quality product possible. 

 

Various Benefits of a Chain Pulley Block
 

Enhanced efficiency
The most significant benefit of having chain pulley blocks is that it offers a mechanical advantage to a user. This means that employees would have to use less effort to lift heavy loads, increasing the overall efficiency of the lifting process.
With the increased efficiency that a chain pulley block offers, the potential risk of the industry is reduced, increasing workers' productivity levels. Moreover, with this equipment, one can lift a wide range of heavy loads, therefore eliminating the need for multiple machinery.

 

Highly versatile
A chain pulley block is a highly versatile piece of equipment for lifting heavy weights. You can use it in various areas, such as maintenance, manufacturing and construction. The chain pulley block can also be used to lift and shift heavyweights in construction sites, factories, and warehouses with the least effort.
In addition to using a CPB outside, you can also use it indoors as well. This way, you don't have to invest in different types of lifting equipment for indoor and outdoor lifting. Having one chain pulley block is enough to satisfy a wide range of lifting needs.

 

Advanced level durability
Business owners or individuals with a need for weightlifting machinery look for durability in their invested machinery. If 'durability' is an essential consideration for you, the chain pulley block has got you covered.

 

Easy to operate
Not all the places or industrial areas which are engaged in heavy load lifting have trained workers. This is the reason why most official bodies look for load-lifting machinery that is easy to operate.
The chain pulley blocks we offer are user-friendly. Therefore, the workers will spend more time using the chain pulley blocks than learning how to operate them. This will save a good amount of time and effort, adding to the efficiency of the whole process

 

Portability
What's better than having lifting equipment which can be moved around without any inconvenience? A chain pulley block is one of the best portable lifting equipment in the market. In a construction site or industrial work, the need for lifting heavy weights can arise indoors as well as outdoors.
In such cases, having a chain pulley block will be helpful. One can simply put out its attachments and move the machinery anywhere one wants.

 

Space-saving
When we talk about heavy weightlifting machinery, the first image that comes to our mind is of large equipment. Chain pulley blocks are one of those compatible with weight-lifting equipment. Compared to other machines, a chain pulley block doesn't occupy a large space. Instead, it's space-saving, giving the workers around full convenience for movements.

 

Low maintenance requirement
Maintenance is an expensive concept when it comes to material handling equipment. The overall strength of the chain pulley block, when combined with its low maintenance capabilities, becomes a perfect load-lifting equipment. The best part about having a chain pulley block is that users don't have to invest more in maintenance.

 

How to select a good Manual Chain Pulley Block
 

 

Select the right capacity
Are you venturing into the arena of chain blocks without knowing your industry's capacity? This is possibly the greatest mistake that you can make at the outset. In general, the block capacity ranges from 0.5 tonnes to roughly 50 tonnes to accomplish pulling and lifting heavy loads. First and foremost, define the capacity requirements based on the needs of your company. Chain Pulley blocks that have a capacity of more than 50 tonnes can be customized. Selection of the capacity should be based upon the weight of the heaviest material you intend to lift with the chain block
 

Selecting the suitable mounting (hook mounted or trolley mounted)
You are ready with the capacity down to the decimal point, but what about the mounting? Like the capacity, this also has to be decided based on your application requirements. You can either choose a fixed mounted (hook mounted) or a trolley mounted chain block. Trolley mounted ones are beneficial if you wish to shift the load on girders. Hook mounted ones are helpful if the blocks will remain static in a single location for an elongated period.
 

Select triple spur gear system
A good chain pulley block will always have a triple spur gear system in it. It not only minimizes the risk of workplace hazards but at the same time, makes the job effortless. Gone are the days of Manual chain pulley blocks with Worm drive mechanisms. One should always concentrate on depending on a system that is a blend of an efficient spur gear and a sturdy chain pulley lift with a suitable chain length.
 

Load chain made up of alloy steel
The load chain of the chain pulley block should be made up of Grade 80 - alloy steel. The most important point you need to consider while buying a chain pulley block is that the load chain is not manually welded. You just have to take the effort of ensuring that a single chain piece replaces the load chain. Moreover, refrain from using chain links that have been welded. No matter what is the diameter of the chain, manual welding will always stand a chance of failure during load handling.
 

Chain length should be selected correctly
One should have proper knowledge regarding the types of equipment before using this. The thumb rule you should follow here is this – measure the height of the lift. Make sure that the load chain length is equal to the lifting height and hand chain is almost two feet less than the lift length. For example, if the length of the lift chain block is 20 feet, then that of the hand chain should be 18 feet. However, it is feasible to keep the load chain length more than that of the lift length.
 

Spare parts that can be altered (easily interchangeable parts lead to versatility)
If you are seeking long-term use and not just short-term satisfaction, this parameter will be particularly helpful. Always verify whether the chain block's standard parts can be interchanged without much cost or effort. This might seem unimportant now, but you will thank us when there are inevitable wear and tear. These interchangeable parts will allow you to accomplish repairs quickly and ensure a quick return to normal functioning. The standardized aspects of such parts will further guarantee that you can get the parts replaced easily. If you select a chain pulley block that has interchangeable spare parts, then the advantage that you will have is you can get them replaced at any point in time.  

 

FAQ

Q: What is the purpose of a chain block?

A: The chain block is a mechanism used to raise or lower heavy loads with relative ease. The internal gears of the chain block wind the chains around, lifting the object that is attached to the end or hook. This means that very little force is required to lift large, heavy loads of up to 30,000 kg.

Q: What are the different types of chain blocks?

A: There are two main types of chain pulley blocks: manual and electric. Manual chain pulley blocks are operated by hand, while electric chain pulley blocks are powered by electricity. Manual chain pulley blocks are ideal for lifting lighter loads and are commonly used in small shops and garages.

Q: What is the difference between electric and manual chain hoist?

A: Manual chain hoists (also known as chain blocks) require physical effort to lift loads, making them ideal for low-frequency use and smaller loads. Electric chain hoists use motors, offering efficient lifting with less physical strain, suitable for frequent use and heavier loads.

Q: What is the difference of chain block and lever block?

A: Chain block is used to lift and lower heavy loads vertically, while lever hoist is used to pull and lift in both vertically and horizontally or multi-directional positions. Lever hoist is operated using one hand by cranking the handle/ lever forward or backward.

Q: What are the rules for chain block?

A: Every block must contain one number or one. When two or more blocks are in contact at a corner it is called a "chain". All blocks must be part of a chain. A chain cannot contain more than one block of one size and shape.
