Three major adverse phenomena in the construction machinery maintenance market

Time:2024-04-28 Click:131

Engineering machinery such as port cranes and dock cranes are prone to major or minor malfunctions during use. In such cases, seeking maintenance from the maintenance department is a common method for customers to solve this problem. According to Yuanwang's understanding, there are currently some adverse phenomena in the construction machinery maintenance market, such as:

1. Blind disassembly and unloading, unable to accurately determine and analyze faults

Some maintenance personnel, due to unclear understanding of the structure and principles of construction machinery, improperly analyze the cause of faults, and cannot correctly determine the fault location. They blindly dismantle and dismantle the equipment with a "rough and close" mindset, resulting in not only the original fault not being eliminated, but also new problems due to poor maintenance skills and processes.

2. Blindly replacing parts and repairing, blindly replacing parts

The determination and elimination of faults in construction machinery are relatively difficult. Some maintenance personnel always use the method of replacement testing, regardless of the size of the parts, as long as they believe that the parts that may cause the fault are replaced one by one, the results not only fail to eliminate the fault, but also replace the parts that should not be replaced at will, increasing user expenses.

3. Not checking the quality of new parts, new faults occur after assembly

Before replacing the parts, some maintenance personnel do not conduct technical inspections on the new parts and install them directly onto the construction machinery. This approach is unscientific. It should be noted that the quality of spare parts sold in the current market is uneven, with some counterfeit and inferior parts filling the gap. Additionally, some parts may undergo functional changes due to long inventory times, and if not inspected, they can often cause malfunctions after assembly.

The existence of these phenomena has led to low quality mechanical maintenance and poor equipment reliability, causing customers to suffer various losses. We would like to remind relevant industries to stand in the perspective of customer safety interests and pay attention to the following when repairing engineering machinery products:

1) Mechanical faults should be detected through detection equipment or traditional methods to prevent blind maintenance without detection;

2) After inspection, the repairable parts should be repaired appropriately to prevent blind replacement of parts;

3) When replacing accessories, it is recommended to choose a manufacturer from * *, and avoid choosing high-quality and cost-effective products solely for immediate benefits;
