The inspection items for explosion-proof electric hoists after initial installation are crucial to ensure the safety and reliability of the equipment. The following are the main inspection items required for the initial installation of explosion-proof electric hoists:

1、 Appearance and structural inspection

Check the overall appearance:

Ensure that the explosion-proof electric hoist is not damaged, deformed, or corroded.

Check all fasteners for tightness and no looseness.

Check explosion-proof performance:

Confirm that the explosion-proof level of the explosion-proof electric hoist matches the explosion hazard level of the installation site.

Check whether the explosion-proof structure of the explosion-proof electrical equipment is complete, without damage or deformation.

2、 Electrical system inspection

Cables and wires:

Check whether the cables and wires are intact, without damage or exposure.

Confirm that the specifications of the cables and wires meet the design requirements and leave a safety margin.

Electrical connection:

Check if the electrical connections are secure, free from looseness or poor contact.

Confirm that the connection of electrical circuits meets explosion-proof requirements.

Electrical parameters:

Measure electrical parameters such as voltage and current to ensure they are within the normal range.

3、 Mechanical system inspection

Chain or wire rope:

Check the wear of the chain or wire rope, and there is no severe wear or breakage.

Confirm that the fixing and connection of the chain or wire rope are firm and reliable.

Pulley and drum:

Check whether the rotation of the pulley and drum is flexible and there is no jamming phenomenon.

Confirm that the surface of the pulley and drum is smooth, without cracks or severe wear.

Braking system:

Test the braking effect of the brake to ensure reliable braking and no slipping phenomenon.

Check the wear of the brake and replace or adjust it if necessary.

4、 Inspection of safety and protective devices

Limit device:

Check whether the up and down limit devices are sensitive and reliable, ensuring that they can automatically stop when reaching the limit position.

Buffer device:

Check if the buffering device is intact and effective, and can provide cushioning during impact.

Safety warning signs:

Confirm that clear safety warning signs and operating instructions are affixed to the equipment.

5、 Functional testing and operational checks

No load operation test:

Run the test without load to check if the operation of each component is normal.

Load running test:

Gradually increase the load for testing and check the stability and reliability of the equipment under load.

Abnormal detection:

During the testing process, pay attention to whether there are any abnormal sounds or vibrations in the monitoring equipment and promptly troubleshoot any faults.

6、 Special requirements for explosion-proof electrical equipment

For explosion-proof electrical equipment, special attention should be paid to the following inspection items:

Explosion proof electrical equipment and electrical circuit connection:

Construction should be carried out according to relevant regulations, especially at the wiring ports of explosion-proof electrical equipment, which should be reliably treated to ensure explosion-proof performance.

Environmental adaptability inspection:

Take corresponding protective measures according to the specific installation environment, such as waterproofing, moisture resistance, corrosion resistance, heat resistance, vibration resistance, etc.
