What is A Chain Block? Easy Guide

A chain block is a lifting mechanism that’s used to assist you in raising and lowering heavy items with ease. The internal gear of the chain block allows the chain to rotate, allowing items to be lowered or raised. The lifted item is attached via a hook, chain blocks can support up to 30,000kg.  

Chain blocks are commonly used in places such as garages to lift out/in car engines, factories, warehouses, construction, retail and agriculture.

What are the components of a chain block?

The components that make up the chain block are the hand chain, cog, drive shaft,gears, load chain sprocket and load chain.

How much can a chain block lift?

The amount of weight a chain block can lift will depend on the chain block. It can typically support 30,000kg (66,138lb) with ease and do so for years. 

How does a chain block work?

When the hand chain is pulled, it turns the cog, the cog will then turn the drive shaft, which turns the gears, which turns the load chain sprocket. This lifts the load chain and the load with 30x more force than was pulled.

Your force is multiplied 30x when pulling with a chain block.


A chain block will be operated manually and sometimes electronically if it has that feature. This is important to know if you’re looking for lifting equipment that can be operated manually. The chain block is perfect for this.

If you want something electric operated, go with an electric hoist

What’s the difference between a chain block and chain hoist?

A chain block is a manual piece of lifting equipment and a chain hoist will be operated electronically. Chain blocks are used to vertically lift items and chain hoists will be used to lift items horizontally.
