When using low clearance electric hoist cranes, corresponding preventive measures should be taken at different stages to ensure safe and efficient operation. The following are the precautions for each stage:

1、 Installation phase

Site selection and layout:

Ensure that the installation area has sufficient clearance height to avoid collisions with surrounding obstacles.

The ground should be solid and flat, providing sufficient support to prevent the crane from overturning.

Fixed and Stable:

The crane must be securely fixed and equipped with suitable anchoring devices to ensure that it does not move during operation.

When installing guide pulleys and drums, ensure that the ropes are arranged neatly to avoid crossing or squeezing.

Electrical connection:

The electrical system should be installed by professionals to ensure good grounding and prevent electric shock accidents.

All electrical components shall comply with safety standards and be equipped with leakage protection devices.

2、 Preparation before operation

Inspection and maintenance:

Before operation, conduct a comprehensive inspection of the crane, including key components such as wire ropes, chains, hooks, and brakes.

Ensure good lubrication and no loose or damaged components.

Load assessment:

Confirm the load weight, which must not exceed the rated lifting capacity of the crane.

Check the binding and fixing methods of the load to ensure safety and reliability.

Personal protection:

Operators should wear appropriate personal protective equipment, such as safety helmets, safety shoes, gloves, etc.

Ensure that there are no idle personnel in the operation area and set up warning signs.

3、 Operation phase

Smooth operation:

Start and stop smoothly, avoid sudden acceleration or deceleration, and prevent load shaking.

Overloading, diagonal pulling, or using cranes to drag ground objects are strictly prohibited.

Pay attention to observation:

Pay close attention to the operating status and load situation of the crane during the operation process.

If any abnormal sound, vibration or odor is found, the machine should be stopped immediately for inspection.

Follow the signal:

Operators should closely cooperate with signal command personnel and comply with command signals.

In situations where the line of sight is unclear or the environment is complex, the operation should be stopped.

4、 Post operation maintenance

Shutdown and power outage:

After the operation is completed, park the crane in the designated location and cut off the power supply.

Reset the controller to zero, lock the operating device, and prevent unauthorized use.

Cleaning and inspection:

Clean up debris and dust from the crane and operating area, and maintain cleanliness.

Conduct daily inspections of the crane, record its operation status, and promptly identify potential issues.

Regular maintenance:

According to the manufacturer's recommendations, regularly perform professional maintenance and repairs on the crane.

Replace worn parts to ensure that the crane is always in good condition.

5、 Safety Training and Management

Operator training:

Operators should receive professional training and be familiar with the performance, operating procedures, and safety precautions of the crane.

Regularly conduct safety education and skill assessments to improve the safety awareness and operational level of operators.

Safety management system:

Establish a sound safety management system and clarify the safety responsibilities of personnel at all levels.

Develop emergency plans, regularly organize drills, and improve the ability to respond to emergencies.
