At HYNEE, the road from drawing to mass production runs through a full validation programme, and the travel test is one stage of it. The Hi13 has recently completed this test.

Starting With the Drive Assembly
Every travel movement of the
Hi13 — starting, moving straight, turning, braking — is driven by the drive assembly. When the machine is in motion, the drive assembly is also the point where load and vibration concentrate most.
After a full cycle of continuous running, most other components remain much as they were, while the drive assembly has already been through wear, temperature rise and seal ageing. These changes are slow and hard to notice in the short term; only after they accumulate do they appear as a fault.
The purpose of the travel test is to bring these changes into view while the machine is still in the factory: the prototype runs continuously under defined conditions, its condition after long running is observed, and measured data is used to verify whether the unit is ready for production.
The New Product Department Leads Throughout
The test is owned end to end by HYNEE's New Product Department: it defines the purpose, designs the test conditions, and sets the acceptance criteria. Keeping that responsibility in one place is what keeps the standard consistent from start to finish.
Two Hi13 prototypes were used. Testing took place on site, with the machines running straight, turning left and right, and repeating the cycle — close to how they travel on a real jobsite.

Throughout the test cycle, running condition was recorded at each stage — voltage, current, temperature rise, abnormal noise and vibration, appearance — every item entered into the record sheet. Any abnormality or fault was documented separately, with the symptom, cause and corrective action noted, and the test resumed only after the issue was resolved and recovery confirmed.
Five Areas of Inspection, Verified One by One
The test covers five groups of inspection:
Structure — mainly the machine's appearance and fasteners: the loss of bolt preload and hairline cracks in housings and brackets under prolonged vibration. These are hard to detect in the short term, yet they are often the most hidden source of failure in a travel system.
Sealing — checks for oil leaks and the condition of seals. Vibration from long periods of back-and-forth travel makes oil seals age readily.
Temperature rise — measured at motor windings, gears and bearings. Heat build-up under continuous running is a direct cause of motor damage and reduced lubrication performance.
Wear — focused on key contact areas. This item speaks to the long term: whether the machine still holds the same accuracy and noise level after a year of service.
Electrical performance — rotational speed, current and power are recorded, and changes in these values directly reflect a decline in efficiency.
In addition, insulation resistance, abnormal noise, vibration and sound levels were recorded as criteria throughout.
All items were recorded before, during and after the test, and the data sets were compared item by item. Judgements rest on measured values.
Only Three Possible Conclusions
Every item is judged as pass, fail or pending. If any single item falls short, the unit is not released.
What the Travel Test Means
For the machine itself, this is a long-cycle inspection before shipment: whether it can be released is supported by data either way.
For customers, the process translates into something concrete: fewer early-stage failures, fewer unplanned stoppages, maintenance intervals that can be planned ahead, and a total cost of ownership that is easier to calculate.
For HYNEE, this is a repeatable method: purpose before testing, standards before results, judgement before release. Every conclusion is backed by records, giving customers one more thing they can verify for themselves when choosing equipment.
The Hi13 travel test is now complete and all inspection records have been filed. The conclusion will be reached against the established criteria and will serve as the basis for mass production and quality control.
Safer work at height is built on verification, step by step.
