In this blog, you will be gaining knowledge about a chain pulley block working and its different types. The chain block system is also known as a manual hoist, used in different sectors for lifting and lowering heavy loads. If you are struggling to lift items in your factories or construction sites, you can use this lifting equipment. Chain pulleys are used in industries for machine installation and product repair. They also operate effectively in factories, plants, and on building sites.

Chain blocks incorporate an Overload Limiter (or OLL) function to avoid overload lifting.  How does this work? The handwheel of this hoist, equipped with a washer and clutch disc, slips its clutch whenever the draw force on the chain reaches its maximum limit.  As a result, the force is not communicated to the sprocket; hence, the weight is not hoisted by the hoist.

Design & Construction of a Chain Pulley Block:

Chain pulley blocks, also known as differential pulleys and occasionally “chain hoists,” are mostly used in enterprises to physically raise large and heavy items and industrial equipment, such as automobile engines. These pulleys feature durable gears, alloy steel chains, and wheels.    They work by tugging on a slack of continuous chain that is coiled around two pulleys. The maximum weight capacity is dictated by the relative sizes of the connecting pulleys. To minimize slippage, ropes have recently been replaced by chains, and pulleys by sprockets.

Chain Pulley Block Working: Explained Below!

A manual hoist or chain block system works on the simple mechanical principle. The main components of this chain block system are a load chain, a hand chain, and hooks. To begin, attach the object to the bottom hook of the chain block and pull the hand chain. When you pull the hand chain, the gear system of this lifting equipment transfers the pulling force to the load chain. Gears inside the block rotate and lift heavy loads with the help of the lifting chain. The manual hoist also has a brake system that holds the load in its position without slipping. 

You should always follow the right chain pulley block guide to get the most out of your lifting equipment. Your lifting equipment comes with a product manual that contains detailed instructions on how to use and maintain it. 

Here are the Chain Pulley Block Types

Chain blocks are commonly used in garages due to their lifting qualities, which enable them to rapidly and effectively remove engines from vehicles. They are an extremely efficient way to carry out actions that would normally require more than two people. 

This lifting equipment is used for industrial installation and maintenance purposes. They are also suitable for overhead work and small spaces. You can also use a manual chain pulley block with trolley to move the loads horizontally and vertically. 

This lifting equipment is available in different types, such as

  • Manual chain blocks
  • Pneumatic chain blocks
  • Motorised chain pulley blocks

Know About the Standard Codes Before You Buy the Chain Pulley Block

Before you buy a chain block or a manual hoist, look for its safety features, lifting capacity, build quality, and other specifications. Also, you should look for safety standards like HSN codes. The chain pulley block HSN code is used for trade and taxation and helps identify it as lifting machinery equipment under government norms.
