A used mast climbing work platform should not be evaluated only by age, paint condition or whether it moves up and down during a short demonstration. The important questions are whether the machine can be positively identified, whether the components belong to an approved configuration, what maintenance and repairs have been carried out, and whether the equipment is suitable for the intended project.
This checklist is designed for purchasing due diligence. It is not a substitute for inspection by a competent technical person.
1. Confirm the machine identity
Start with the basics:
- manufacturer,
- model,
- serial number,
- year of manufacture,
- rated capacity,
- available technical documentation,
- declaration/certification information where applicable,
- previous owner or fleet history if available.
The machine identity should match the documentation and major components. Avoid relying only on verbal descriptions such as "same as model X" or "compatible with model Y."
2. Check whether the components form a compatible system
A used package may contain mast sections, platform modules, drive units or electrical parts from different periods or sources. Visual similarity is not proof of compatibility.
Ask for confirmation that:
- mast sections are the correct type,
- platform modules belong to the approved system,
- drive units and control components match the model,
- tie components are compatible,
- safety devices belong to the machine configuration,
- any modifications are documented and approved.
Do not assume parts from different machines can be combined simply because dimensions appear similar.
3. Review the maintenance and repair history
Request available records for:
- planned maintenance,
- major repairs,
- replaced components,
- electrical work,
- drive-system work,
- structural repairs,
- safety-device service,
- incidents or overload events if recorded.
A machine described as "fully maintained" should have more evidence than a sales statement. Records help a technical reviewer understand what has been changed and what may require further inspection.
4. Inspect structural components carefully
A competent inspection should consider the condition of:
- mast sections,
- platform structure,
- chassis/base structure,
- guardrails and gates,
- connection points,
- weld areas,
- corrosion-prone zones,
- deformed or repaired components.
Fresh paint can improve appearance but should not be treated as evidence of structural condition.
5. Check the drive and braking systems
Mechanical drive components deserve particular attention because wear or previous failure may not be obvious from a brief unloaded test.
HSE has published a safety alert on mechanical failure in mast climbing work platforms, highlighting the importance of detecting failures in relevant drive arrangements. That alert should not be interpreted as a defect statement about all MCWPs; it is a reminder that technical inspection must go beyond appearance.
The inspection scope should follow the design and maintenance requirements of the actual machine.
6. Check electrical and control systems
Confirm that the control system, limit devices, emergency functions and safety circuits are present and appropriate for the model.
Do not bypass, bridge or disable safety devices to "make the machine work" during a test. Any fault should be investigated and corrected through the proper technical process.
For ALPMAKSAN machines, model-specific technical support can be discussed through technical service.
7. Verify documentation, not just hardware
A used machine without usable documentation can create problems during installation, maintenance and future resale.
Ask for:
- operation manual,
- maintenance instructions,
- load information,
- electrical diagrams where supplied,
- parts information,
- inspection/maintenance records,
- certification documents applicable to the machine,
- records of approved modifications.
Documents should match the actual machine and configuration.
8. Evaluate the machine against the intended project
A technically serviceable used machine may still be the wrong choice for a particular job.
Compare the intended project with:
- required working height,
- required working length,
- load distribution,
- facade geometry,
- site access,
- tie locations,
- electrical supply,
- installation logistics.
The right question is not only "is this machine functional?" but also "is this machine suitable for the configuration we need?"
9. Build a total acquisition cost
The purchase price is only the starting point. Add:
- required repairs,
- missing parts,
- transport,
- installation,
- commissioning,
- training/familiarisation,
- initial maintenance,
- documentation work,
- spare parts required for reliable operation.
If a repair cost is unknown, do not assume it is zero. Mark it as an unresolved cost until a technical assessment or quotation is available.
Then compare the used option with a new purchase and rental alternative for the same project need. See Buy or Rent a Mast Climbing Work Platform?.
10. Complete handover and familiarisation
Used equipment still requires correct handover. Operators and relevant personnel must understand the machine-specific controls and safety systems.
The final delivery record should identify the equipment, included parts, documents, completed repairs and any open conditions.
Frequently asked questions
Is a newer used machine automatically better?
No. Age is only one factor. Configuration suitability, maintenance history, current condition and documentation must be assessed together.
Can mast sections from different machines be mixed?
Compatibility must be confirmed from the manufacturer's technical information and competent assessment. Similar appearance is not enough.
Does "serviced" mean "ready for my site"?
No. Maintenance condition and project suitability are separate questions. The intended installation must still be evaluated.
Should I buy a used machine without records if the price is attractive?
Missing records increase uncertainty. The technical and commercial risk should be understood before purchase rather than assumed away.
Evaluate the machine before evaluating the discount
Contact ALPMAKSAN technical service or share your project requirements to discuss inspection, support or equipment options. This article is not a statement of current used inventory or a warranty for any specific machine.
