What measures should be taken when the highway bridge erecting machine fails?

To solve the failure of highway bridge erecting machine, some urgent measures should be taken to determine the cause of the accident. The method is to perform several successive electrical directional operations to see if the object is accelerating and falling. If the failure state still exists after closing the operating handle, it should be the mechanical failure of the highway bridge erecting machine. At present, there are two situations that should be treated differently.

What measures should be taken when the highway bridge erecting machine fails?

In the process of operation, the sudden failure of highway bridge erecting machine occurs in the operation mechanism of large vehicles or small vehicles. At this point, emergency power outage should be adopted. If the problem is that the elevator is faulty, the power supply fault cannot be handled at this time. Operators should pay attention to personal safety and send out emergency signals. Ground personnel should cooperate with the control device to make the hook land safely. There is another case, that is, there is no fault case, which means that the road bridge erecting machine has an electrical fault or error fault. If an electrical fault occurs, the power supply needs to be cut off. If it is a false failure, it needs to be examined carefully to make a judgment.

In case of mechanical accident, the driver should keep calm and not panic. As the highway bridge erecting machine is a large machine, so the consequences of the accident is unimaginable. Therefore, when mechanical failure occurs, the driver should immediately determine the cause of the failure and take corresponding emergency measures, and immediately communicate with the ground personnel to ensure the safety of the operator.

The solution of road bridge erecting machine failure:

When the bridge erecting machine breaks down, it is necessary to take some urgent measures to determine the cause of the accident. The method is to perform multiple electrical direction operations to see if the object is accelerating. If the fault persists after closing the handle, it should be a mechanical fault of the bridge. At present, it is divided into two cases and should be treated differently.

In one case, the failure occurred in the operating mechanism of the cart or in the operating mechanism of the cart. In this case, an emergency power outage method is required. In both cases, the failure occurred in the elevator. In this case, the power supply fault rectification method cannot be used. Staff should pay attention to personal safety and send out emergency signals. Personnel on the ground should work with the controls so that the hooks can be safely lowered.

Of course, there is another case, that is, there is no fault state, which means that the highway bridge erecting machine has electrical failure or optical failure. At this point, if it is an electrical fault, you must turn off the power. If it is an illusion, you need to examine it carefully to determine. Check the rim and pedal regularly. When the rim part is worn or cracked to 10% thickness, a new wheel should be replaced. When the difference in diameters between the two driving wheels on the tread exceeds D / 600 or there is a serious defect in the tread, the vehicle should be reignited. The highway bridge erecting machine should be inspected once per shift. The brake of highway bridge erecting machine should be operated accurately and the pin should not be stuck. The brake shoes shall be properly mounted on the brake wheels and the brake shoes shall have equal clearance when the brake is released.
