• Used time: 10 years (as of this return visit)

• Maintenance times: 2

• Maintenance content: a. Tool daily wear and tear replacement   b. Maintenance and replacement of the main shaft

C — Problems and Solutions

In the recent return inspection, we found that customer did not regularly check their bearing screws when using ‍Longhe large blow moulding pallet crusher. ‍The loosening of the bearing screws and the loosening of the main shaft may lead to serious wear of the machine and even breaking of the main shaft. Therefore, we strongly recommend that customers not only add an appropriate amount of butter to the machine, but also check the bearing screws to ensure that they are not loose.

Loose or broken bearing screws may cause the performance of the machine to decline or even fail, thus affecting production efficiency. In order to ensure the normal operation of the crusher and extend its service life, customers should establish a regular inspection mechanism at least once a week. In addition, it is recommended that customers use professional tools to lock the screws immediately when they find them loose to avoid potential security risks.

By taking these measures, customers can ensure crushing and normal operation, reduce failure rates, increase production efficiency, and extend their service life.

D — Customer evaluation

User experience - Mr. Li: This machine is very good to use, but sometimes there will be some minor problems, but it does not affect the use.

Service experience - Boss Jiang: I bought Longhe crusher, and there is an after-sales return visit. It feels very good and considerate. Few other brands of equipment have such a good service.

E — Summary of the return visit

After a field visit by Longhe technicians, we provided workers with a detailed explanation of machine maintenance. In the communication with workers, we have found some possible problems with products and have begun to improve them. At the same time, we also learned that after the business expansion of customers in recent years, the existing production capacity may not be able to meet the demand. Therefore, we have formulated new solutions for customers to help them improve production efficiency and meet growing needs. We will continue to pay attention to the production of customers and provide necessary support and help.
