How to maintain a loader after 5,000 hours of use?

Adhere to the implementation of the "Two Determinations and Three Guarantees" system

The operators of loaders should be assigned specific personnel and machines, and be guaranteed to use, store and maintain them. They need to achieve "three understandings" (understanding structure, principle and performance) and "four abilities" (being able to use, maintain, inspect and troubleshoot common faults). Correctly use the loader, strictly follow the safety technical operation procedures, implement target cost management for mechanical equipment, link the economic benefits of the operator with the loader usage fee (such as fuel cost, maintenance cost, upkeep cost, material cost, tool cost, etc.), and change the passive daily maintenance and upkeep of the loader driver to active daily maintenance and upkeep of the equipment.

Reduce the invisible wear and tear on loaders caused by environmental climate

That is, to reduce the impact of environmental factors on its service life. As most construction machinery operates outdoors and its operation sites frequently change, its performance is greatly affected by factors such as the temperature, environment and climate of the operation site. For machinery that operates in a fixed manner for a long time, there must be a machine room (shed), or maintenance measures such as covering the top and supporting the bottom with wood should be taken to reduce the invisible wear and tear caused by sun exposure, rain and rust. Many construction units have overlooked the impact of environmental factors on the use of machinery (low environmental temperatures can also cause disastrous consequences for machinery). No corresponding protective or adaptive measures were taken, resulting in a decline in the performance of the machinery, a shortened service life, and even accidents.

Regular maintenance of loaders is the key to extending their service life

The "Regulations on the Warranty of Road Construction and Maintenance Machinery of the Ministry of Transport" has clear provisions for the maintenance of loaders. However, many construction units often neglect maintenance work when the schedule is tight and the tasks are heavy, believing that the machinery is operating normally without faults and there is no need to stop for maintenance. This sows the seeds of potential mechanical accidents in the future. Because maintenance can eliminate mechanical hazards, if it is not maintained in time, it often leads to major malfunctions of mechanical equipment and even personal injury accidents. This not only increases maintenance costs but also delays the construction period.

Adopt advanced mechanical detection and other auxiliary maintenance methods

Mechanical maintenance work is an important link in extending the service life of machinery. Adopting reasonable maintenance methods can effectively prolong the service life of construction machinery. According to relevant statistics, the adoption of advanced condition monitoring methods can reduce maintenance costs by 25% to 50%, lower the failure rate by 75%, and extend the service life of machinery.

Low-cost and rapid repair method

The "low-cost and rapid repair method" proposed by the machinery industry is also an effective way to extend the service life of machinery. To implement this method, in addition to adopting maintainability design in mechanical design to enhance the maintainability of machinery, the following methods can also be used in maintenance practice:

One is the replacement of parts. Many parts on construction machinery, such as the track pins of bulldozers and excavators, and the cylinder liners of diesel engines, often bear unidirectional loads during operation, which leads to uneven wear. If the positions of the parts subject to uneven loads are replaced in a timely manner to balance their wear, their service life can be prolonged.

Second, by adopting advanced brush plating and adhesive repair technologies, failed parts can also be repaired quickly and at a low cost. Such as wear-resistant surfacing welding, diamond electroplating layer spraying, magnetic electroplating, laser electroplating, etc.

When we buy machines, they are not merely tools to make money for us. We should cherish these big creatures as if they were our own children, paying attention to their maintenance and correct usage at every stage. This can save us a considerable amount of maintenance costs and also make our daily work more worry-free and effortless.
