Four routes that should not share one quotation label
The current service page describes procurement of imported-brand components, original used dismantled units, original-factory remanufactured units for some older specifications, and local manufacturing/custom work. [2] These are supplier claims about offered routes; origin and condition must be established for the actual item.
| Requested route | Evidence tied to the offer | Buyer decision |
|---|---|---|
| New component | Actual maker, full code, drawing, origin and warranty issuer | Approve the exact unit and interfaces |
| Used or remanufactured replacement | Serial/condition, known history, remanufacturing party/work and current test report | Accept defined condition, remaining uncertainty and terms |
| Repair of your own unit | Incoming identity, findings, replaced parts, approved work and return tests | Authorize repair scope before additional work |
| Custom assembly or machine upgrade | Approved circuit/assembly drawing, included items and integration responsibility | Validate the resulting mechanism as a system |
Catalogue brand headings and “original” sourcing language do not establish authorized dealer status or genuine origin of an individual unit.
A component and service business in Haishu
宁工液压（宁波）有限公司 identifies its address in Gaoqiao, Haishu, Ningbo. Its introduction describes manufacture/sales of hydraulic components and support for road, mining, construction, marine/port and forming machinery, including non-standard manufacture and upgrades. [1] These are company-wide scopes rather than independently verified installations.
- Reported test equipment
- The company states 90 kW power/pressure/flow monitoring equipment for piston pumps and motors.
- What this does not establish
- No witnessed bench, calibration record, exact test envelope or tested order unit is authenticated by CivilEquip.
- Catalogue and service examples
- QJM ball-piston entries, motor/pump repairs, travel assemblies and hydraulic valves have separate pages.
Use the bench claim to ask for the selected unit’s actual test conditions and report, not to assign 90 kW as that motor’s rated output. The detailed QJM page adds model families, brake and through-hole variants. [3] Those distinctions belong in the selected order code.
Put approval gates into a repair enquiry
- 1
Record the incoming assembly
Identify unit/serial, reported symptoms, circuit, recent events and known prior work. Agree transport, intake inspection and estimate charges.
- 2
Approve findings and parts
Receive the inspection findings, proposed replaced/reworked components, parts origin and changed cost/schedule. Define whether unusable major parts can stop the repair.
- 3
Agree the return evidence
Specify dimensional and functional/performance checks with test conditions and acceptance; record removed parts, final configuration and instructions.
The website publishes repair and spare-part services. [4] This approval sequence is a buyer’s proposed agreement, not a witnessed factory procedure. HSE’s alert emphasizes OEM-compatible replacements and proper pressure-test precautions. [5] Repair and recommissioning should use the actual equipment instructions and competent personnel; this page supplies no DIY pressure procedure.
Clarify warranty and paid support together
The service page states 3–12 months of warranty for complete assemblies and describes remote guidance, on-site installation/commissioning, delivery and fault testing as paid services. [2] It does not assign one duration or service price to every product.
Warranty wording
Ask which duration applies, when it starts, the covered unit/condition, exclusions, remedy and transport responsibility.
Field support
Agree location, charges, travel, scheduling and work boundary. “After-sales support” alone does not define a free call-out.
Stock and delivery
Request current identity/quantity and a written delivery basis. A warehouse-value claim or old stock announcement is not an item reservation.
