The single beam suspension leg locking device plays a crucial role in ensuring safety. The design and use of this device aim to prevent accidental movement or detachment of the suspension legs during crane operation, thereby ensuring the stability of the crane and the safety of the operators.

1、 The function of the locking device

Fixed suspension leg: The locking device can firmly fix the suspension leg, preventing it from shaking or falling off during crane operation.

Improving stability: By locking the suspension legs, the device can significantly enhance the overall stability of the crane and reduce safety risks caused by the movement of the suspension legs.

Protecting operators: The locking device provides a safer working environment for operators and reduces potential hazards caused by unstable cranes.

2、 Types and characteristics of locking devices

Mechanical locking device:

Principle: Fix the suspension leg in a predetermined position through mechanical structures such as bolts, pins, etc.

Features: Simple structure, easy operation, high reliability.

Hydraulic locking device:

Principle: Use the pressure generated by the hydraulic cylinder to lock the suspension leg in the desired position.

Features: Flexible operation, strong locking force, suitable for large cranes.

Electromagnetic locking device:

Principle: The suspension leg is attracted to a fixed position by the magnetic force generated by the electromagnet.

Features: Fast response speed, easy control, suitable for cranes with high degree of automation.

3、 Suggestions for safe use of locking devices

Regular inspection and maintenance: Regularly inspect and maintain the locking device to ensure that it is in good working condition. This includes checking the wear and lubrication of the locking mechanism, as well as the fastening of the connecting components.

Proper use of locking device: Before operating the crane, ensure that the locking device is correctly installed and locked in place. Avoid operating the crane when the locking device is not fully locked.

Adhere to operating procedures: Strictly follow the operating procedures of the crane to avoid unsafe behaviors such as overloading and overspeed. These behaviors may result in the failure or damage of the locking device.

Training operators: Conduct regular safety training for operators to understand the working principle, operating methods, and safety precautions of locking devices. This helps to improve the safety awareness and operational skills of operators.
