The cause of the failure of hydraulic oil drum handling machinery is not only related to human factors and time factors. But Dan is related to environmental factors. Under normal conditions of use, loading and unloading trucks and handling machinery of a given manufacturing level have their own failure rules, but when conditions change, the failure rules of oil drum handling machinery will also change. Due to the wide variety of hydraulic trucks, The working conditions are complex and the failure forms are various. The reasons for the man-made failure of the hydraulic pallet truck can be summarized into three aspects.
Even if the designer thinks it is the perfect handling machine. In fact, there are always weak links. These weak links are generally caused by inadequate design considerations, conditional constraints or design errors.
1. Poor consideration When designing loading and unloading trucks and handling machinery, many unknown factors are often encountered, such as new environments that have not been extensively studied, new materials whose performance has not been fully mastered, and the load ratio and strength of the parts. Judgments, failure forms, etc. may contain unknown factors of varying degrees. In the development process of new loading and unloading trucks and handling machinery, the design methods are often determined based on existing data and familiar engineering principles. In this situation, it is inevitable that there are potential failure factors in loading and unloading trucks and oil drum handling vehicles.
2. Conditional restrictions Various conditions will also bring unreliable factors to loading and unloading trucks and oil drum handling machinery. For example, the existing materials or standard parts do not have the performance expected by the designer, but they cannot be due to supply or cost constraints. Use more ideal materials. Or parts, sometimes complex parts due to performance and weight limitations, can not use redundant design with low failure rate; in addition, due to the limitation of processing conditions, the reasonable processing technology required by the design cannot be used. Obviously, it is natural that the failure rate of loading and unloading trucks and oil drum handling machinery is high due to such various constraints.
3. Design errors In the design, due to the lack of reliable material performance data, the material strength performance and its inherent defects are not considered properly, or the traditional design methods are not reasonable enough, causing the deviation between the classic design theory and the actual situation Too big, due to lack of experience, there are weak links such as breaks and sudden changes, uneven thickness, sharp corners, etc. when designing the geometric shapes and dimensions of the parts. In short, the main aspects of the "congenital deficiency" in the design of these oil drum handling machinery are oil. The hidden dangers of failure of barrel handling machinery.
