Chain blocks

A chain block is a device consisting of two grooved wheels with a chain wrapped around them in the same fashion as a block and tackle. Chain blocks take the strain out of heavy lifting, potentially reducing the number of people needed for a job and reduce the chancy of a heavy item from being damaged.

– Store and handle chain blocks correctly.

-Inspect chain blocks and accessories before use and before placing into storage. 

-For top hook suspension, use hooks that are fitted with safety catches, or mouse the hook, ensuring the support fits freely into the seat of the hook. 

-For trolley suspension, ensure the trolley is correctly set for the beam width.  Check that the bottom hook will reach its lowest point without running the chain fully out.  –

Adopt safe slinging practices and follow the instructions for the safe use of the equipment used. NEVER:

-Expose chain blocks to chemicals, particularly acids, without consulting the supplier. 

-Replace the load chain with a longer one without consulting the supplier. 

-Use undue effort to force the block to operate. 

-Throw, drop or drag a chain block. 

-Allow oil or grease to come into contact with the brake. 
Selecting the Correct Block Hand chain blocks are available in a range of capacities and with various types of suspension. Select the block to be used and plan the lift taking the following into account: Type of suspension – hook, trolley etc. Capacity, class of use and range of lift. Chain blocks are designed for vertical lifting only. Consult the supplier if the block is to be used in areas of high risk, exposed to the elements, water, steam etc, with hazardous substances, e.g. acids** or chemicals, or subjected to extremes of temperature. Storing and Handling Hand Chain Blocks Never return damaged blocks to storage. They should be dry, clean and protected from corrosion. Store blocks by their top suspension with chains clear of the ground, the chains may be wrapped together to facilitate this. Non-portable blocks stored outdoors should be covered and protected from corrosion. Blocks should not be dropped, thrown or dragged across the floor.
