What are the treatment measures for bridge cranes when they encounter a sudden power failure?
Cranes are often used in material transportation and construction sites. Because they are frequently used, their maintenance-free performance is the common pursuit goal of users and manufacturers. There are also differences in maintenance measures between the crane as a whole and its components, and the work intensity And the operating environment is a direct factor in the maintenance-free performance. The power supply failure is in addition to the crane's ability to self-check and maintenance-free. In this case, in addition to responding to emergencies, what are the requirements for the driver to provide guidance and help?
If there is a power failure during the operation, the driver should meet the following requirements:
1. Under suitable conditions, put the brake on or install other safety devices.
2. All power supply should be cut off or the clutch should be in the neutral position to avoid accidental operation after the power is restored.
3. If feasible, use the control of the brake to put the suspended load on the ground smoothly.
4. At the beginning of each work shift, the driver should check all control devices. If abnormal operation of the control device is found, it should be debugged and repaired before the hoisting machinery is operated.
5. The driver should be familiar with the equipment and its normal maintenance. If the hoisting machinery needs to be debugged or repaired, the driver should promptly report the situation to the management staff and inform the driver who takes over.
6. When the crane is operated at night, there should be sufficient illumination in the construction work area. If the illumination is insufficient, the illumination should be guaranteed before lifting and hoisting, reducing the blind area of vision, and beware of all kinds of operation accidents.
When operating the crane under climatic conditions where the track or structure of the crane is icy or the visibility around it is reduced, the speed should be slowed down or effective means of communication should be provided to ensure the safe operation of the crane, and the impact of low temperature in winter on electrical equipment Need to pay attention.
Don’t worry if you encounter problems when operating the crane, deal with it calmly, deal with all kinds of failures properly, and better use the crane to serve the production.
