“…After a minimum time of 10 minutes, the excess developer was removed using conjugated air with a maximum pressure of 0.034 MPa. The control was carried out in a control cabin under the UV lamp and a minimum radiation intensity of 1200 μW/cm2 on the surface and by the light intensity in the cabin that does not exceed 20 lux on the checking surface [21,22].…”

The successful management of product incompatibility remains a challenge. Therefore, the study aims to analyze the possibilities of effective management through qualitative analyses. The sequence of two quality management techniques added to the fluorescent method was proposed. These techniques were the Ishikawa diagram and the 5Why method. For a specific incompatibility example identified by using the penetration tests (the fluorescent method), the causes of these incompatibilities were searched using the Ishikawa diagram and the 5Why method. An analysis example was the linear indication problem on the product surface, the gasodynamic sealer. By supplementing the penetration method, the proposed sequence of selected quality management techniques has shown that it is possible to detect incompatibilities and identify the source cause, also. In turn, finding the source cause can allow proposing the improvement actions. The proposed solution can also be used in other quality problems and other enterprises to improve the production processes.

“…Wire rope is one of the most frequently used loading and bearing tools in various engineering applications, such as elevators, cableways, bridges, cranes, and hoisting equipment, and plays a significant role in guaranteeing human life and property [ 1 , 2 ]. However, plenty of defects regularly occur in the in-service steel wire rope owing to damage and failure both in strength and structure, which may cause severe accidents and even fatalities.…”

The quantitative defect detection of wire rope is crucial to guarantee safety in various application scenes, and sophisticated inspection conditions usually lead to the accurate testing of difficulties and challenges. Thus, a magnetic flux leakage (MFL) signal analysis and convolutional neural networks (CNNs)-based wire rope defect recognition method was proposed to solve this challenge. Typical wire rope defect inspection data obtained from one-dimensional (1D) MFL testing were first analyzed both in time and frequency domains. After the signal denoising through a new combination of Haar wavelet transform and differentiated operation and signal preprocessing by normalization, ten main features were used in the datasets, and then the principles of the proposed MFL and 1D-CNNs-based wire rope defect classifications were presented. Finally, the performance of the novel method was evaluated and compared with six machine learning methods and related algorithms, which demonstrated that the proposed method featured the highest testing accuracy (>98%) and was valid and feasible for the quantitative and accurate detection of broken wire defects. Additionally, the considerable application potential as well as the limitations of the proposed methods, and future work, were discussed.

“…The research was conducted using the ropes of loading cranes, mining winches, cableways, cable-stayed bridges, pillar chimneys, antenna masts, overhead transmission lines and other installations. In the article [10], the authors presented the results of their own research on the NDT method application for the assessment of ropes used in cranes. The authors focused their attention on the application of this method to assess the internal condition of ropes.…”

The working surface of lift guide rails during operation is exposed to the destructive action of catchers under emergency braking conditions. In most cases, this surface is lubricated with grease, which makes it impossible to visually assess their local wear. The comfort of cabin movement on guide rails and thus the feelings of cabin occupants depend on the condition of guide rails. Therefore, the verification of lift guide rails wear under real conditions (in situ) is quite cumbersome. In order to assess them on a monthly basis, they would have to be completely cleaned and the excessively worn areas would have to be measured with universal measuring tools and re-lubricated. Such activities would only be a waste of time and lubricant. Therefore, the concept of a magnetic head was developed to assess the technical condition of lift guide rails. The head, which uses permanent magnets, makes it possible to measure the dispersed magnetic field of the guide rail cross-section. The areas of excessive wear show changes in this field, so it is possible to identify these areas without a need to remove lubricant from their surface. This paper presents both the detailed design of a developed head and the preliminary results of measurements using it. As the lift guide rails can have different dimensions depending on the lifting capacity, the developed head was equipped with inserts having the dimensions compatible with the guiding part width, thus enabling measurements that can be taken on different types of guide rails. The developed head and methodology allow measurements to be made without the need for disassembly, i.e. under in situ conditions. The results obtained in the laboratory have shown that the head concept and the measurement methodology are suitable for measurements in situ and perfectly fill the gap in this field of mechanical engineering.
