Your Guide To Selecting The Right Chain Block

WHAT EXACTLY IS A CHAIN BLOCK?
A chain block, also known as a block and tackle, is a method of lifting heavy loads using a sprocket-driven chain that has been reduced through a series of gears so that it can be driven by hand using another (non-load bearing) chain and sprocket.

WHAT IS THE PURPOSE OF A CHAIN BLOCK?
Chain blocks are typically used in places where there is no power. Chain blocks are used to lift light or heavy loads vertically where precision, rather than speed, is essential.

They can be used safely and easily by one person, such as when a technician needs to carefully lower a hoist into place or remove a motor from a tight spot.

THE ESSENTIAL COMPONENTS OF A CHAIN BLOCK

Load sprocket or main sprocket
This unit is intended to manage a specific load and chain dimension.

Chain

Mated perfectly with its sprocket and comes with various forms of weather protection. Galvanized chain, for example, will provide greater resistance to moisture and rust.

Pawl
This is a unidirectional gearing mechanism that runs freely when the hand wheel is turned up but has angled teeth and a pawl that holds the load when the hand wheel is not turned on.

Case of the gearbox
The gearbox or reducer This is where the magic happens, multiplying the operator’s effort and allowing them to lift heavier loads. Gears must be kept lubricated and free of dust and debris.

Chain and hand wheel
As the name implies, this is the part that connects the operator to the equipment.

ADVICE FOR Buying A CHAIN BLOCK
Look for brands that provide maximum safety protection (overload protection) and provide better value in terms of life span and cost of ownership. Be wary of brands that use non-standard chain sizes, as this may reduce your productivity when distributors run out of stock. Non-standard chains are also significantly more expensive than standard chains, with no discernible quality improvement.
