For explosion-proof electric hoist cranes, taking appropriate precautions at different stages of use is crucial to ensure safety and reliability. Here are the key precautions for each stage:

1. Pre-use Precautions

Installation and Inspection:

Install the explosion-proof electric hoist crane strictly according to the manufacturer's instructions and relevant safety standards.

Conduct a thorough inspection before use, checking the mechanical structure, electrical components,钢丝绳 (wire ropes), hooks, limit switches, and other safety devices to ensure they are in good condition and functioning properly.

Verify that the power supply voltage meets the requirements (typically 380V, with a variation range not exceeding ±20V).

Test Runs:

Perform no-load test runs to check the operation of the hoist, including the lifting, lowering, and traveling mechanisms.

Ensure that all limit switches and safety devices are sensitive and reliable.

2. Operational Precautions

Load Capacity:

Never exceed the rated load capacity of the hoist. Overloading can lead to equipment failure and pose a serious safety hazard.

Ensure that the load is properly secured and balanced before lifting.

Operation Procedures:

Operate the hoist smoothly, avoiding sudden starts and stops.

Do not tilt the load or use the hoist as a horizontal dragging tool.

Keep a safe distance from the load during operation to prevent accidents.

Environmental Considerations:

Ensure that the working environment is within the specified temperature and humidity range for the explosion-proof hoist.

Avoid operating the hoist in areas with explosive gases or dust unless it is specifically designed for such environments.

3. Maintenance and Inspection Precautions

Regular Maintenance:

Establish a regular maintenance schedule for the hoist, including lubrication, cleaning, and tightening of bolts.

Check the condition of the wire ropes, chains, and hooks regularly, replacing them if they show signs of wear or damage.

Electrical System Checks:

Regularly inspect the electrical components, including the motor, contactors, and wiring, for signs of damage or overheating.

Ensure that the electrical connections are tight and free from corrosion.

Safety Device Testing:

Test the limit switches, overload protection devices, and other safety devices regularly to ensure they are functioning correctly.

4. Post-use Precautions

Shutdown and Storage:

After use, shut down the hoist properly and disconnect the power supply.

Store the hoist in a dry, ventilated area away from corrosive substances and extreme temperatures.

Documentation and Reporting:

Keep detailed records of all maintenance activities, inspections, and repairs.

Report any issues or malfunctions immediately to the maintenance department or relevant personnel.
