Some machines leave a company's fleet quietly. Others stay so long that they become part of the family.
In 2009, a customer in Grenada, in the West Indies, bought a CHANGLIN ZL30 wheel loader. He used it personally, mainly for one job: loading gravel. Seventeen years later, in 2026, that same machine is still working.
The ZL30 has never had a fleet manager, a maintenance team or a workshop behind it. It had one owner who needed it to work — and it worked. Year after year, load after load, the machine did its job in Grenada's heat and coastal air.
Today it carries the marks of seventeen years of service. And that is exactly what makes its owner's words worth reading.
After so many years of work, the machine's transmission and brake systems now need repair. Rather than replacing it immediately, the owner contacted us to look for original spare parts — the first step in keeping a machine of this age in service.
We checked the machine's requirements, located the corresponding parts and sent him a quotation. A simple request for spare parts, on paper. In reality, a conversation about how long a machine deserves to keep working.
Two sentences from that conversation stayed with us.
The first was his summary of the machine:
"It's very faithful."
The second was his intention:
"I want to keep this machine for another 10 years."
He also told us that the hydraulic system is still doing its job — "All pumps is working." — and that on one hydraulic cylinder, he has never had to change a seal: "I never changed any seal in one hydraulic cylinder."
For a machine bought in 2009, still loading gravel in 2026, those are not marketing claims. They are field notes from seventeen years of work.
In the end, the repair plan was discussed at home, with his son. His son's view was short and practical:
"The machine is old."
So the decision was balanced: the ZL30 will keep working for a few more months while the family starts preparing to buy a new machine.
That is the honest part of this story, and it is why we are publishing it. A machine that has given seventeen years is not a machine that failed. It is a machine that finished a long career — with a replacement being planned, not rushed.
Durability is often written as a number in a brochure. Real durability looks different: it looks like an owner calling after seventeen years to ask for original parts, because he still wants the machine to work.
That call is also a reminder of what our job is after the sale. Machines like this ZL30 stay in service because they can still be repaired, and because parts and technical support remain available years after delivery. Supporting long-life machines is not a slogan for us; it is the part of the business that decides whether a customer's second machine is also ours.
Every machine's service life depends on how it is used, how it is maintained and how it is supported. This owner's experience is his own — and after 17 years, it is one worth telling.
Stories like this one depend on something practical: parts that still exist, and a manufacturer that still answers. For owners of older loaders, three habits make the difference:
If the machine is beyond economic repair, the next step is a new one — and the specification for that machine should start from the work it will do.
17 years. Still working.
If you own an older machine and need genuine parts to keep it working, or you are planning its replacement, contact Dingsheng Tiangong for a project-specific recommendation. Please provide your company name, project location, machine model and year, the parts or equipment required, quantity, working conditions, destination port and expected purchase date. Our team will respond with a parts and equipment proposal, not a generic price list.
