When operating and maintaining a grab bridge crane, attention should be paid to the following aspects to ensure the safe and reliable operation of the equipment and extend its service life:
1. Preparation before operation
Equipment inspection
Inspect the grab, wire rope, pulley, brake, electrical equipment, etc. to ensure that all components are not damaged, worn or loose.
Ensure that the opening and closing mechanism and hydraulic system of the grab are working properly, without any leaks or malfunctions.
Check if the track is flat and unobstructed, ensuring that the crane's running path is unobstructed.
Environmental inspection
Clean the operating area to ensure that the ground is level and free of obstacles.
Confirm weather conditions and avoid operating under strong winds, heavy rain, or adverse weather conditions.
2. Precautions during operation
Correct operation
Operators should undergo professional training and be familiar with the operating procedures and safety requirements of cranes.
When operating, one should be fully focused, avoid distractions, and strictly follow the operating steps.
The start and stop operations should be smooth, avoiding emergency starts or stops to prevent equipment damage and heavy objects falling off.
Load control
Strictly operate according to the rated load of the equipment to avoid overloading or unbalanced loading.
Confirm that the grab bucket has fully grasped the heavy object before lifting to avoid slipping or material scattering.
safe distance
Ensure that no personnel stay or pass through the working range of the crane to prevent accidental injuries.
Keep the operating table and work area clean to avoid interference from debris during operation.
3. Inspection and use of safety devices
Limit switch
Regularly check the working status of the limit switch to ensure that it can effectively stop the movement of the crane when it exceeds the predetermined range.
Overload protection device
Ensure that the overload protection device is working properly to prevent the equipment from operating under overload conditions.
Regularly calibrate and test overload protection devices to ensure their sensitivity and reliability.
Emergency stop system
Familiar with the operation of emergency stop systems to ensure that equipment can be quickly stopped in emergency situations.
Regularly inspect the emergency stop button and circuit to ensure their normal operation.
The safe operation and maintenance of grab bridge cranes are crucial. Regular inspection, correct operation, and timely maintenance can ensure the safe and reliable operation of equipment, and extend its service life. Operators should strictly abide by operating procedures and safety precautions, maintain a high sense of responsibility and professional competence, and ensure the safe and efficient operation of the crane under various working conditions.
