What are the safety precautions for chain blocks?

Chain pulley blocks represent a specific type of lifting equipment that operates by employing chains to elevate and descend loads. These devices make use of a pulley system to attain a mechanical advantage. In the context of heavy lifting operations, efficiency and safety assume critical significance. Consequently, it becomes essential to bear in mind essential guidelines to ensure the secure and effective utilization of chain pulley blocks. This article aims to explore these tips, assisting in maximising efficiency and establishing a safe working environment.

1.     Choose the Appropriate Chain Pulley Block

The first step in ensuring safety and effectiveness is choosing the proper chain pulley block for your unique lifting requirements. When making your decision, take into account elements like environment, lift height, and weight capacity. Make sure the chain pulley block you choose satisfies your lifting needs, complies with industry safety standards, and is appropriate for the environmental conditions it will be exposed to.

2.     Inspect and Maintain Regularly

The safe operation of chain pulley blocks depends on routine inspections and maintenance.  Check the chain, hooks, and pulleys and closely inspect the chain pulley block for any signs of wear and tear, such as broken chains, hooks, or sheaves, before each use.

Lubricate moving parts as recommended by the manufacturer. To address any potential problems and lengthen the equipment’s lifespan, schedule routine maintenance as well.

3.     Ensure Proper Installation

The chain pulley block must be installed correctly to avoid accidents and increase safety. When mounting the block, be sure to carefully follow the manufacturer’s instructions and secure it to a solid, load-bearing structure. Don’t rush the installation process; doing it wrong can result in mishaps and equipment breakdowns.

4.     Train and Educate Operators

The safety and efficiency of chain pulley block operators can be enhanced through proper training and education. Educate them on equipment inspection, safe operation techniques, and emergency response protocols. Regularly assess the skills and knowledge of operators and provide refresher training when necessary. Well-trained operators are more adept at mitigating risks and ensuring effective operations.

5.     Inspect the Lifting Area

Check the designated area for potential hazards before beginning any lifting tasks. To prevent accidents, ensure a clear path, make the area secure, and remove any obstacles from the area. Find any overhead obstructions that may hinder the lifting operation and remove them. In addition to reducing risks, a neat and organised lifting area makes the lifting process easier and safer.

6.     Implement Correct Lifting Techniques

Proper lifting techniques must be adopted to maintain control and reduce the risk of accidents. Establish clear signals and commands with the lifting operation team through communication. Before lifting, make sure the load is balanced and securely fastened. Use smooth and controlled motions to avoid sudden movements or swings.

7.     Regularly Review and Update Safety Procedures

As technology progresses and the demands of the workplace evolve, it is vital to periodically evaluate and enhance your safety protocols. Keep yourself informed about the most recent industry standards, regulations, and make appropriate adaptations to your procedures. Maintaining a proactive and knowledgeable stance can establish a secure and efficient working environment that benefits all individuals.

Some Essential Chain Pulley Block Safety Dos and Don’ts: You Can’t Afford to Miss

Dos:

• Ensure the chain pulley block has the appropriate SWL capacity for the load to be lifted
• Verify that the chain pulley block and all lifting accessories have the appropriate certifications
• Maintain proper distance during the lifting operation
• Throughout the lifting process, wear the proper personal protection gear
• Place the hook directly over the load’s centre of gravity
• The chain pulley block should only be used for vertical lifting
• Include knowledgeable and skilled individuals in the lifting operation

Don’ts:

• Avoid loading the load abruptly or with sudden jerks
• Never lift, support, or transport people using a chain pulley block
• Never throw or drop the chain block onto the ground
• Never stand close to a load that is being lifted or suspended
• Never use a chain pulley block without the necessary instruction and permission
• When lifting, suspending, or lowering the load, be careful not to exceed the safe working load limit
• Never leave the load that is suspended unattended

Precautions for use of chain block

 

1） Before using the chain block, carefully check whether the rotating part is flexible, whether there is chain clamping, whether the chain is broken and cracked, whether the brake is safe and reliable, whether the pin is firm, and whether the hanging rope and support beam are firm and stable. It can be used only after passing the inspection.

 

2) When in use, check whether the lifting chain is twisted. If it is twisted, it can be used only after adjustment.

 

3) When in use, first pull the bracelet back and loosen the lifting chain to make the chain fall have sufficient lifting distance. During operation, pay attention to tensioning slowly to make the chain gradually stressed. The formal operation can be carried out only after there are no abnormalities.

 

4) In the lifting operation, overload is strictly prohibited. No matter where it is in use, the zipper shall be in the same direction as the sprocket to prevent the zipper bracket. The force of the zipper shall be uniform and shall not be too fast or too fierce. When it is used in the horizontal direction, the chain shall be supported by a cushion at the entrance of the thin chain to prevent failure.

 

5) During the use of the chain block, the number of zippers shall be determined according to the lifting capacity of the chain block. When the hand zipper cannot be pulled, the reason shall be found out, and the number of people shall not be increased or pulled sharply, so as to avoid the fracture of the lifting chain due to excessive stress.

 

6) When lifting an object, if it is necessary to suspend the object temporarily, the hand zipper shall be tied to the lifting chain to prevent accidents caused by chain fall self-locking failure.

 

7) The rotating parts shall be lubricated regularly to prevent the chain from rusting. The chain seriously rusted and with broken marks or cracks shall be scrapped and renewed and shall not be used.

 

8) The chain and steel wire rope shall be inspected once every six months, and the test shall be conducted once a year at 25% of the rated load of the hoist.
