The following are some key points regarding the hazardous content and preventive measures for the installation of electric chain crane chain boxes:

Hazardous content

Improper chain installation: If the chain is installed unevenly, it may cause shaking and instability during operation, thereby increasing operational risks.

Insufficient motor protection: If the motor is not equipped with an appropriate protective cover, it may be damaged due to water ingress or foreign object intrusion.

Excessive force at the elbow: Excessive force on the chain at the elbow may cause chain wear or even fracture.

Electrical connection issues: If the electrical components inside the cabinet are not clearly labeled, the wire numbers do not match the actual wiring, or the wiring is loose, it may cause electrical faults.

preventive measure

Ensure smooth installation of the chain: When installing the chain, it should be ensured that the chain is flat and there is no obvious shaking during operation.

Add motor protective cover: In order to prevent water ingress or other foreign objects from entering, the motor should be equipped with a protective cover.

Pay attention to stress at the elbow: Avoid excessive force on the chain at the elbow to reduce wear.

Standardized electrical connection: The electrical components inside the electrical cabinet should be correctly labeled, the wire numbers should match the actual wiring, and the wiring should be tightened without looseness. The design of the electrical cabinet should meet the three-phase five wire system, and each motor should have overheat protection and air switch control.

Regular inspection and maintenance: Regularly inspect and maintain the electric chain crane to ensure that all components are in good condition.

Follow the operating procedures: During the operation process, the operating procedures of the electric chain crane should be strictly followed to avoid overloading and improper operations such as diagonal pulling of heavy objects.

Training operators: Provide professional training to operators to ensure that they understand and master the operating methods and safety precautions of electric chain cranes.
