Request a technical equipment inspectionHow the calculation works
The checklist has 20 questions in five weighted categories: external condition (20%), mechanical and technical condition (25%), electrical and control system (20%), documentation and history (15%), and safety and compliance (20%). Questions are rated 0–4 and the result is a weighted average of 0–100 with a radar chart. Below 40 points indicates poor condition, 80 and above very good.
Example: if only the mechanical (25%) and electrical (20%) categories are at maximum and the rest are missing, the result is 45/100, i.e. “average – needs a closer assessment”.
Frequently asked questions
Does the tool replace a technical inspection?
No, it is a structure for a proper inspection. For critical machines, involve a specialist.
What must I check without fail?
Mechanical wear, the condition of the control system, documentation, spare parts availability and safety systems.
What if the result is average?
Use the shortcomings to negotiate a lower price, or order a closer assessment before purchase.

Methodology and limitations
Methodology based on standard industry calculations and Maintest’s practical industrial experience. This tool provides a planning estimate and does not replace project-specific engineering assessment. This tool is a screening and planning aid developed by Maintest. Results are indicative and depend entirely on the figures and answers you enter. They are not an engineering calculation, a safety assessment or a substitute for the manufacturer’s instructions, applicable standards or professional judgement. Weights, benchmarks and default values are Maintest planning assumptions and can be adjusted to your situation. Do not use this tool as the only basis for safety-critical decisions such as lifting, electrical work or lockout procedures.
