Crane Maintenance

Analysis and elimination of crane fault inspection

The whole crane and its components and metal structures are under the action of overload stress, repeated stress, and environmental corrosion, and gradually produce defects from their own failure mechanism. These defects are divided into one defect and two defects. Loosening, deformation, wear, fracture and deterioration are a defect. They are called direct defects. Defects due to a defect are called two defects, such as vibration, noise, heat, leakage, pollution and so on. These defects (failure modes), through the transmission mechanism, will affect the overall performance and strength of the crane. The change of the fault mode and nature and strength is the sign of the anomaly: the observation and measurement of the parameters of the symptoms can predict the occurrence of the fault.

The overhead bridge crane fault diagnosis technology includes two parts: one is the primary technology to diagnose the normal condition of the crane, the simple diagnostic technology is mainly implemented by field operators; the two is the precise diagnosis technology, which is mainly implemented by professionals for decision-making.

Function of simple diagnostic technique

  • The tending control of the stress and the detection of abnormal stress in a crane or part.
  • The deterioration of the crane or its equipment, the trend control of the fault and the early discovery.
  • The trend control and abnormal detection of the performance and efficiency of the crane or its equipment.
  • The trend control and abnormal detection of the performance and efficiency of the crane or its equipment.
  • Points out parts or structures showing fault performance.

The goal of the precise diagnostic technology of precision diagnostic technology is to diagnose the “probably abnormal” location by special diagnostic technology, so as to determine the necessary measures and techniques. It should have the following functions:

  • Determine the type and type of abnormal.
  • Analysis and elimination of crane fault inspection
  • Understand the cause of the abnormality.
  • Understand the degree of danger and predict the results of its development.
  • Understand the way to eliminate the failure state.

A method of obtaining diagnostic information

There are two main methods to obtain diagnostic information, one is the direct observation and judgment of the senses, and the two is instrument detection and analysis. The first hand information on the condition of parts and components can be obtained by the direct sensory observation, and then the judgment is made according to the experience. This method can only make qualitative judgments about the observed parts, and often use simple instruments to enrich the sensory observation ability. Instrument detection is a special fault diagnosis instrument for crane and parts vibration and noise measurement, temperature measurement, wear particle analysis, crane or parts performance measurement, to quantitative analysis of faults.
