1. Main car body unit: Contains driving motor, mechanical brake and independent fall‑protection locking mechanism. It runs along ladder‑mount guide rail and bears operator plus tool cargo weight.
2. Foldable evacuation platform: Provides standing position during normal lifting operation; can be flipped upward, allowing technicians to step over unit and escape along original ladder for power‑loss emergency evacuation.
3. Reinforced guide rail: Fixed onto existing ladder rungs, supports car‑body travelling track and strengthens original ladder mechanical performance.

4. Down‑tower main control cabinet: Realizes bottom‑site remote control of whole unit; stores operation status and fault‑recording data.
5. Wireless remote‑control unit: Enables lifting‑operation control by operator staying on car platform, convenient for tool‑material transportation work.
6. Obstacle‑detection sensor assembly: Installed on car‑body bottom; triggers instant stop‑once collision against barrier occurs inside tower.

1. Dual Independent Fall‑Protection Safety Structure
The car‑body built‑in fall arrester operates separately from operator personal safety arrester, implementing redundant locking protection to lower personnel‑fall risk under unexpected mechanical failure.
2. Triple‑Mode Multi‑Location Operation Control
Supports on‑car manual handle operation, wireless remote‑control and ground‑based down‑tower cabinet control, offering flexible operating options for different on‑site work scenarios.
3. Foldable Emergency Evacuation Step Design
Platform can be folded upwards during power‑loss or equipment breakdown, technicians can cross over lift unit and evacuate by original vertical ladder without extra rescue hardware.

4. Collision‑Avoidance Bottom Obstacle‑Sensing Function
Physical touch‑sensor mounted on car bottom triggers immediate halt upon hitting tower‑internal obstacles, preventing hardware deformation and personnel injury from impact events.
5. C4‑Grade Anti‑Corrosion Mechanical Construction
Main frame adopts aluminum‑steel composite material with C4 anti‑corrosion surface treatment, delivering long‑term stable performance under offshore salt‑spray and inland cold‑climate wind‑farm environment.

1. On‑shore Wind‑Turbine Routine Maintenance
Suitable for frequent daily inspection, component overhaul and heavy‑tool transportation inside on‑shore wind turbine towers. It eliminates manual‑climbing physical consumption; technicians reserve full energy for actual turbine repair work.
2. Off‑shore Wind‑Farm Tower Service Work
Applied inside offshore wind‑turbine towers; C4 anti‑corrosion treatment copes with marine salt‑mist atmosphere. Evacuation step guarantees safe retreat path for operators under offshore power‑loss emergencies.

3. High‑Frequency‑Visit Industrial Tall Tower Access
Deployed for industrial tall towers requiring repeated staff access, such as large‑size power‑plant chimney access; improves daily work throughput by cutting physical‑climbing time loss.
4. New‑Energy Wind‑Farm Retrofit Upgrade Project
Ideal for existing wind‑farm reconstruction projects. It can be retrofitted on original tower ladder without tower‑body modification work, shortening project shutdown‑duration during equipment upgrade.
