When using chain hoists for lifting operations, in order to ensure the safety and efficiency of the operation, the following aspects need to be noted:

1、 Preparation before lifting

Choose the appropriate chain hoist:

Select the appropriate chain hoist specifications and materials based on factors such as weight, volume, and shape of the lifted items.

Ensure that the chain hoist can withstand the weight and stress of actual operations, and has characteristics such as wear resistance and corrosion resistance.

Check the chain hoist:

Before use, conduct a comprehensive inspection of the chain hoist, including components such as chains, hooks, connecting pins, nuts, etc.

Check the chain for wear, breakage, deformation, etc. If there are any abnormalities, replace it immediately.

Check whether the hook has cracks, wear, deformation, etc. If there are any abnormalities, it should be replaced immediately.

Ensure that fasteners such as connecting pins and nuts are securely fastened without any looseness.

Determine the lifting point and center of gravity:

Mark the lifting points and weight data, determine the weight and center of gravity of the lifted object.

Ensure that the lifting point is firm and reliable, capable of supporting the weight of the lifted object.

Cleaning the lifting area:

Check if there are any obstacles in the lifting area, and remove them in advance if there are any.

Set up a warning line to ensure that non operators stay away from the lifting area.

Operator preparation:

Operators must undergo professional training and hold relevant qualification certificates.

Operators should be familiar with the structure, performance, usage methods, and safety precautions of chain hoists.

2、 Precautions during lifting process

Trial lifting:

Before formal lifting, a trial lifting should be conducted to confirm that the lifting equipment and lifting points are firm and reliable.

Control speed:

During the lifting process, the operator should steadily control the lifting speed to avoid severe shaking or sudden acceleration/deceleration.

Maintain smooth communication:

Operators should maintain smooth communication and follow the instructions of the commanding personnel.

Pay attention to the lifting angle:

Ensure that the chain hoist can withstand tension in the vertical direction and avoid abnormal twisting or bending forces.

Choose the appropriate lifting angle based on the shape and center of gravity of the lifted object.

Avoid overloading:

Overloading the use of chain hoists is strictly prohibited, ensuring that the load borne by the hoist does not exceed its rated load.

Observe the lifting status:

The operator should closely observe the status of the lifted items and lifting equipment, and immediately stop the operation if any abnormal situation is found.

3、 Handling after lifting

Check the lifting equipment:

After the lifting operation is completed, a comprehensive inspection of the chain hoist should be carried out to ensure that there is no damage.

Clean up the site:

Clean up the lifting site and place the lifting equipment in the designated location.

Record data:

Organize relevant materials and keep records for subsequent analysis and improvement.

4、 Safety precautions

It is strictly prohibited to leave the post without authorization:

During the lifting process, operators are strictly prohibited from leaving their posts without authorization.

It is strictly prohibited to stay or walk under the lifted items:

Ensure that no one stays or walks under the lifted items to prevent them from falling and causing injury.

It is strictly prohibited to use damaged lifting equipment:

If defects such as damage, deformation, cracks, etc. are found in the chain hoist, it should be immediately stopped from use and replaced or repaired in a timely manner.

Regular maintenance:

Regularly maintain the chain hoist, including cleaning, lubrication, etc., to extend its service life.
