Wind Turbine Service Lift Repair and Retrofit
Repair and retrofit of service lifts on operating wind turbines. Share the lift make and model, the number of turbines and recent inspection findings, and we will discuss a scope based on our JASO service lift work on 41 turbines.
Service Lift Repair and Retrofit for Operating Wind Turbines
A service lift, also called a tower lift or wind turbine elevator, carries technicians and tools up the tower. When it is out of service, every visit means a long ladder climb, and maintenance slows down across the wind farm.
Gridinta repairs and retrofits wind turbine service lifts on operating turbines. Our experience includes two JASO elevator system campaigns covering 41 turbines in Finland and Latvia. The scope combined lift system repair, retrofit work and ladder alignment, and in Finland it also included validation inspections.
Our IRATA rope access technicians already carry out inspection, maintenance and repair on onshore wind turbines as part of our wind turbine maintenance services. Lift work fits into the same planning: turbine availability, site induction, access, rescue arrangements and a clear record of what was done.
What the Work Can Include
Every lift campaign is scoped against the lift manufacturer's documentation, the operator's requirements and the site rules. Based on the JASO work, a scope can include:
- Repair of service lift system faults and worn components found during inspection or reported by site teams
- Retrofit work defined by the operator, the lift manufacturer or a safety notice, delivered turbine by turbine
- Ladder alignment so that the tower ladder and the lift system work together as one access route
- Validation checks after the work, so each lift is handed back in the condition agreed in the scope
- Work records with completed actions, photographs and any open points for the operator
We discuss lift makes and models other than JASO case by case. Tell us what is installed and what the latest inspection found.
Repair and retrofit evidence from Finland and Latvia
The figures below come from our JASO case study.
| Campaign | Country | Turbines | Scope |
|---|---|---|---|
| Project 1 | Finland | 25 | JASO elevator system repair, retrofit, ladder alignment and validation inspections |
| Project 2 | Latvia | 16 | JASO elevator system repair, retrofit and ladder alignment |
| Total | Finland and Latvia | 41 | Two separate wind farm campaigns inside operating turbine towers |
What this helps you plan: lift repair, retrofit and ladder alignment as one multi-turbine work package, with post-work validation inspections in the Finnish campaign. For another site, send the lift model, defect findings and required changes so we can assess how this experience applies to your system.
Why Wind Turbine Service Lifts Need Attention
Turbine lifts work in a tall, narrow tower with vibration, temperature swings and frequent use by different crews. Until recently, there was no European standard written for them. EN 81-44:2024, Safety rules for the construction and installation of lifts, Part 44: Lifting appliances in wind turbines, was approved by CEN on 30 June 2024. It covers permanently installed, guided lifting appliances driven by rack and pinion or rope traction, including rescue and evacuation. It does not apply to appliances manufactured before its publication, so much of the installed fleet was built to earlier designs.
The UK Health and Safety Executive issued safety bulletin ED01-2024 on service lifts in offshore and onshore turbines in May 2024. A technician suffered serious hand injuries when his hand was trapped between fixed and moving parts while he used the external controls to send the lift down. HSE asked operators to check gate design, guarding and control positions at once, and to reposition controls or add guarding where needed. Findings like these often lead to retrofit work on existing lifts.
Asbestos Brake Pad Alerts in Australia
On 19 December 2025, SafeWork NSW in Australia published an alert on asbestos in brake pads used in wind turbines. It says the pads are used in service lift motors, material hoists, and yaw and rotor brakes. The equipment was imported, and asbestos was found in pads from more than one manufacturer. The alert tells operators to assume all brake pads, including spare parts, contain asbestos until proven otherwise. It also tells them to stop work on lifts with such pads until a competent person has inspected them.
Workplace Health and Safety Queensland followed with its own alert on brake pads used in windfarms on 23 January 2026. Both are Australian alerts and they do not state that European fleets are affected. Operators elsewhere can still ask their lift manufacturer for a material declaration for brake pads and spare parts before planning brake work.
Inspections, Repairs and Who Signs Off
Periodic examination of a turbine lift is a legal duty for the operator. The examiner depends on the country. In Great Britain, HSE explains the six-monthly thorough examination or examination-scheme requirement for equipment lifting people. In Germany, BetrSichV Annex 2, Section 2 assigns lift examinations to an approved inspection body (ZÜS).
We repair and retrofit lift systems, carry out validation checks agreed in the work scope and document the result, so the examiner the operator appoints can complete the statutory examination. Our guide to wind turbine service lift inspection explains the intervals and checks in more detail.
Blade, tower and gearbox checks are quoted separately as turbine component inspection.
Planning a Service Lift Repair or Retrofit Scope
To prepare a practical quotation, share the site location, turbine make and model, lift make and model, the number of turbines, recent inspection or examination reports, fault descriptions and photographs, any manufacturer safety notices, the requested work window, shutdown availability and site induction requirements.
Typical deliverables can include a turbine-by-turbine work record, photographs, completed actions and recommendations for follow-up. Agree the deliverables and acceptance criteria before mobilisation.
