What if there are hidden issues when buying the device back?

＋ －

We offer a 12-month warranty and lifetime online technical guidance. We are responsible for coordinating and resolving core component failures that are not caused by human factors during the warranty period. At the same time, each device undergoes a material testing machine (on-site pumping concrete verification) before shipment to ensure stable performance. You can also choose to go to Changsha to see and test the machine on site, and pay if you are satisfied.

How to deal with malfunctions during the warranty period?

＋ －

When a malfunction occurs, you can contact our technical team at any time and we provide remote video guidance. If remote resolution is not possible, negotiate on-site solutions based on the fault situation. Our after-sales philosophy is "quick response, professional backup" to avoid affecting your project schedule due to equipment downtime.

What does online technical guidance mean?

＋ －

As long as the equipment is purchased from Concrete Yu, you can enjoy free online technical consulting services. Whether encountering operational issues, troubleshooting, or daily maintenance questions, you can contact our technical engineers by phone or WeChat, and we will respond promptly during working hours. This is not just about selling equipment, but also a long-term technical partnership.
