The technical key points of the overweight device for a single beam crane mainly involve the design, installation, use, and safety performance of the device. The following is a detailed explanation of these technical points:

1、 Design points

Structural rationality: The design of overweight devices should ensure structural stability, rationality, the ability to withstand expected loads, and good resistance to deformation.

Material selection: High strength and corrosion-resistant materials such as stainless steel, alloy steel, etc. should be selected to ensure the durability and safety of the overweight device.

Intelligent design: With the development of technology, overweight devices can incorporate intelligent elements such as sensors, control systems, etc. to achieve more accurate and safe overweight control.

2、 Installation points

Accurate installation: The installation of the overweight device should be precise and in place, ensuring a tight fit with other components of the crane and avoiding excessive gaps or misalignment.

Fixed and reliable: The overweight device should be firmly fixed on the crane to prevent loosening or detachment during operation.

Debugging and testing: After installation, the overweight device should be comprehensively debugged and tested to ensure that it can work properly and meet the design requirements.

3、 Key points for use

Operating standards: When using overweight devices, it is necessary to strictly follow the operating procedures to avoid unsafe behaviors such as overloading and overspeed.

Monitoring and alarm: Overweight devices should be equipped with monitoring and alarm systems, which can promptly issue alarms and take corresponding safety measures when the load exceeds the set value.

Maintenance: Regularly maintain the overweight device, check its working condition and wear, and replace damaged components in a timely manner.

4、 Key points of safety performance

Overload protection: The overload device should have overload protection function. When the load exceeds the rated value, it can automatically cut off the power or take other safety measures to prevent the crane from overturning or being damaged.

Stability: The design of the overweight device should ensure the stability of the crane under load, avoiding excessive overturning moment or risk of overturning.

Durability: Overweight devices should have good durability, be able to maintain stable performance during long-term use, and reduce failure and maintenance costs.
