Chain blocks provide versatile lifting solutions. They are used in many settings including construction, factories, rigging, warehousing and more. A chain block is ideal for use on jib cranes and mobile lifting gantry systems.
A chain block may also be referred to as a manual chain hoist, hand chainhoistor block and tackle. Activated manually these hoists are great for lifting heavy loads.
About Chain Blocks
Basically a chain block works by attaching a load, and subsequently pulling down on one of thechains, the chain runs over a gear to raise the load, this increases the mechanical work being carried out by the gear ratio inside the devices housing.
Chain blocks are available in various forms with differing lifting capacities; Some varieties of these chain blocks come with an integrated trolley for convenience, though abeam trolleycan be purchased separately too. and there is also the popular 360 degree chain block which allows full rotation to enable the user to work in nearly all positions, even above the load.
Chain blocks have a brake system to allow the load to be held in a raised position. Most also have an overload prevention system for extra safety sometimes this may be an optional extra; other extras available are chain buckets, which keep the excess chain tidy and out of the way.
Benefits of a Manual Chain Hoist
A chain block provides a convenient and versatile method to lift heavy loads. Chain blocks are quick to fit, portable and cost effective. They are extremely useful for finer, accurate control of the load. Manual chain hoists are frequently used in areas such as workshops. Also anywhere that using an electric hoist isn’t suitable due to lack of power supply or because of hazardous environments.
Chain blocks are compact and therefore relatively portable and offer a great lifting solution for buildings with limited headroom and come in a diverse range with various load capabilities.

THE SAFE USE OF MANUAL CHAIN HOISTS, CHAIN BLOCKS
There are many important safety aspects to consider before using a manual chain hoist / chain block, here we have listed some basic do’s and don’ts.
Use defective blocks, or accessories
Stand under the load
Replace chain with a longer length without consulting supplier
Expose to chemicals, consult supplier
Expose the chain block to the elements, steam or water spray
Lift load over workers
Tip the load
Exceed the WLL
Drag or drop the chain block
Inspect before use, checking for defects, and brake working
Have chain block inspected regularly by qualified person and repaired if necessary
Store and handle correctly
Check bottom hook will reach lowest point without running the chain out fully
Adopt safe slinging practices
For top hook suspension use hooks with safety catches
Check the block is safely rigged, ensure chains are not twisted
Check load is free to move, making sure area is clear
Pull chain smoothly, never jerk
Raise load just clear, then STOP, and check all aspects before continuing
Place load directly in line with top hook, keeping centre of gravity where possible.
