Quality Control & Testing
Each vertical conveyor is inspected throughout fabrication, assembly and testing.
Mechanical structure, electrical control, safety functions and operating performance are verified before shipment.
Reducing installation risks through engineering review, factory testing and documented acceptance.
Quality principle
Test the lifting system, transfer interfaces and safety functions—not only the vertical movement.
A vertical conveyor is more than a lifting mechanism. It combines mechanical structures, drives, sensors, controls and upstream/downstream interfaces.
Quality control therefore follows the project from incoming components through fabrication and assembly to functional testing and final records. Project-specific depth and acceptance conditions are agreed in the order.
Acceptance is an engineering contract
Define what will be proven, how it will be proven and who accepts the evidence.
This page does not promise a universal test script. It shows the information that should be frozen for each project before manufacturing.
Complete conveyor system, lifting mechanism, transfer sections, control system and agreed interfaces.
Actual products or representative loads, including weight range, dimensions and loading orientation.
Operating cycles, sequence logic, throughput requirements, safety functions and agreed acceptance criteria.
X-YES quality team, customer/integrator witness and documented corrective actions where required.
Quality control plan
Six gates with clear objectives, evidence and release conditions.
This structure turns “we test every machine” into a traceable working process.
Key purchased components, identification, condition and project match.
Receiving / inspection record as applicable.
Critical dimensions, structure, workmanship and prepared interfaces.
Drawing checks and in-process inspection.
Drive, guides, transmission, platform or carrier, fasteners and movement condition.
Assembly check and rectification record.
Cabinet, wiring, motors, sensors, devices, I/O and operating response.
Electrical inspection and powered test.
Emergency functions, limits, alarms, interlocks and agreed machine sequence.
Functional test / FAT record as scoped.
Machine status, labeling, documents, packing identification and delivery readiness.
Final inspection and release documents.
Factory acceptance test
A FAT should reflect the real application—not a generic demonstration.
The test product, load condition, sequence, interface simulation and witness method should be confirmed before the machine reaches run-off.
Machine setup condition
Check frame stability, component installation, connections, tension or alignment, lubrication and readiness for power-on.
No-load operation
Observe direction, smoothness, noise, vibration, sequence and abnormal behavior before applying the test load.
Rated-load operation
Verify motion, stability, starting and stopping behavior, transfer and the agreed cycle under representative load.
Safety functions
Check emergency stop, limits, alarms, access-related interlocks and other protective functions within the machine scope.
Abnormal conditions
Verify applicable overload, fault, reset and recovery responses without creating unsafe test conditions.
Final parameters & documentation
Finalize project settings, close deviations, record the agreed results and prepare the release decision.
Complete-machine test matrix
Four connected systems. One acceptance decision.
Individual components can pass and the full route can still fail. The run-off must examine the interactions.
- Frame, guides and moving assemblies
- Drive and transmission condition
- Carrier / platform geometry
- Infeed and discharge alignment
- Cabinet, wiring and field devices
- Sensors, motors and I/O response
- Operating modes and sequence logic
- Interface signals within scope
- Emergency-stop behavior
- Limits, alarms and interlocks
- Guarding / access conditions
- Fault and reset behavior
- Representative product handling
- Transfer direction and orientation
- Load stability and cycle behavior
- Agreed throughput demonstration
Evidence & handover
The release decision should leave a usable record.
Document deliverables vary by contract and destination. They should be listed before design freeze so engineering, testing and final handover are aligned.
Quality FAQ
Define acceptance before the final test day.
Can the FAT use the customer’s actual product?
Where representative products can be supplied safely and on time, they can be included in the agreed test plan. Otherwise, an approved equivalent test load and handling condition should be defined.
Is throughput always proven during factory testing?
It can be demonstrated when the necessary upstream/downstream simulation, product supply and test duration are available. The exact method and pass criteria must be agreed for the project.
What safety functions are tested?
Emergency stops, limits, alarms, interlocks, fault responses and other protective functions within the supplied machine scope are checked. Final line- and site-level risk responsibilities must be separately confirmed.
Can the customer witness testing remotely?
Remote video witness or recorded evidence can be arranged when suitable. Camera coverage, test sequence, document sign-off and time zone should be planned in advance.
How are FAT deviations handled?
Items are recorded, assigned and rectified. The release decision should be based on closure of the agreed acceptance items or a documented disposition accepted by the parties.
Are inspection records supplied with every machine?
X-YES prepares final inspection and project documentation according to the confirmed order scope. Required record types and formats should be listed in the contract.
