Wind Turbine Blade Inspection Robot GT380 | Circular Cold Light | PTZ 10x | 230–3500mm

Wind turbine blade inspection robot GT380 — the industrial CCTV system designed specifically for the internal inspection of wind turbine blades, oil and natural gas pipelines and any infrastructure with a high degree of corrosion, with diameters between 230 mm and 3,500 mm. Equipped with a PTZ camera with 10x optical zoom, a Jiutai-patented distributed circular lighting system and an anti-rollover mechanism, this wind turbine blade inspection robot operates stably within the complex, irregular geometry of wind blades — where crawlers without anti-rollover tip over and lose the image.

The "Distributed Circular Cold Light" illumination — technology exclusively patented by Jiutai — generates a large-area circular light spot with high brightness and uniform distribution, free of shadow points. Unlike systems with concentrated LEDs, this makes the GT380 a wind turbine blade inspection robot capable of visualising fine surface defects — delaminations, matrix cracks and fibre separations — inside composite blades 40–80 m long, with no shadow zones at the edges of the field of view. Key Advantages of the GT380 Wind Turbine Blade Inspection Robot

• Circular Cold Light illumination — Jiutai-patented technology: The "Distributed Circular Cold Light" system generates a uniform, high-brightness circular light spot with no hot spots or shadow zones. The distributed circular lighting eliminates one-sided reflections inside composite blades, ensuring full visualisation of the inner surface without retouching or repositioning to compensate for shadows.

• Integrated anti-rollover — guaranteed stability in inclined blades and pipes: The anti-rollover mechanism keeps the camera platform stable regardless of the inclination of the travel axis or the internal geometry of the wind blade. In blades 50–70 m long with cross-section and inclination variations, the stability of the PTZ platform is the necessary condition for continuous documentation with no image loss.

• 2MP PTZ camera with 10x optical zoom and infinite 360° rotation: The PTZ camera with auto focus, continuous 360° rotation and 220° tilt fully covers the circular or oval cross-section of the wind blade and of large pipes. The 10x optical zoom allows close-up on any suspect defect without repositioning the crawler.

• Dual front + rear camera: Simultaneous documentation with the front PTZ camera and the rear camera eliminates duplicate sessions on the same section — entry and retraction fully cover the internal condition of the blade or pipe in both travel directions.

• Adjustable speed 1–25 m/min — adaptable to the inspection pace: The minimum speed of 1 m/min allows ultra-slow, detailed documentation of zones with identified defects, while the maximum speed of 25 m/min accelerates traversal of intact sections and reduces the total session time on long blades.

• Interchangeable 110/150mm wheel sets: Two optional wheel sizes adapt the GT380 crawler to different diameter ranges: the 110mm wheels for pipes of 230–600mm and the 150mm wheels for pipes and blades of 600–3500mm — a single system covers the entire range without replacing the main platform.

• Laser and 512Hz locator — optional on request: The measurement laser module and the 512Hz locator can be added to the base configuration for projects that require geometric sizing of defects or precise location on the installation map. Both are available on order without modifying the crawler's base platform.

• Automatic inspection reports and optional tablet controller: The inspection report system integrates Full HD video, marked photographs and footage data directly into the automatically generated inspection document. The standard controller is the 10-inch screen; the tablet controller is available as an option for wireless field operation.

Technical Specifications — GT380 Wind Turbine Blade Inspection Robot

Applications — Where the GT380 Wind Turbine Blade Inspection Robot Is Used

A wind turbine blade inspection robot from the GT380 series is the standard tool for the maintenance teams of wind farms that carry out periodic structural integrity audits of fibreglass and composite blades. Internal inspection — accessible through an access port at the base of the blade — allows the detection of delaminations, matrix cracks and water ingress before they become costly failures.

The patented Circular Cold Light illumination, unique to this wind turbine blade inspection robot, compensates for the light absorption of the black inner walls of composite blades, ensuring clear images even at 30–40 m distance from the entry port.

In the oil and natural gas industry, this wind blade and industrial pipe inspection robot is used for long-distance inspections of transport pipelines with a high degree of internal corrosion — galvanic corrosion, pitting, flow erosion and ingress — where push-rod cameras cannot reach and where crawlers without anti-rollover are exposed to the risk of tipping over in pipes with partial residual liquid. Explore the full range of Uzinex industrial equipment for NDT inspection solutions tailored to all types of industrial infrastructure.

The maintenance companies of thermal power plants, renewable energy generation facilities and industrial parks use GT380-type wind turbine blade inspection robot systems for the annual technical audits required by operating regulations and insurance contracts, in line with international non-destructive video inspection standards. The reports automatically generated by the system are compatible with the format required by insurers and energy-sector regulatory authorities. How It Works — How the GT380 Wind Turbine Blade Inspection Robot Operates

• Blade access and crawler launch: The GT380 crawler is introduced through the access port at the base of the wind blade (turbine in service position, with the blade pointing down). The anti-rollover mechanism activates automatically upon insertion — the camera platform stays stable regardless of the initial inclination of the blade's inner channel.

• Controlled advance with adjustable speed: The operator sets the travel speed to the optimal value for the section being inspected — 1–5 m/min in zones with suspected defects or at the base of the blade where structural loading is highest, 15–25 m/min on the intact sections of the central blade.

• Circular Cold Light illumination and PTZ documentation: The distributed circular lighting system ensures uniform brightness across the entire inner circumference of the blade. The PTZ camera rotates 360°, tilts 220° and zooms optically 10x. This makes the GT380 a wind turbine blade inspection robot precise in documenting delaminations, cracks, water ingress and foreign bodies in the composite structure.

• Photographing and marking defects by footage: When a defect is identified, the operator photographs or records video with a single button. The footage counter automatically marks the defect's position along the blade's length — critical information for planning the repair intervention.

• Retraction with the rear camera active: The crawler is retracted with the rear camera active, completing the documentation with an additional image of the blade's rear wall in the exit direction — the session fully covers the inspected section without re-entry.

• Report generation and archiving: The complete inspection report with video, photographs, defect positions by footage and diagnostic conclusions is generated automatically and exported for the turbine's maintenance file, archived alongside the history of previous inspections.

Frequently Asked Questions about the GT380 Wind Turbine Blade Inspection Robot

Why is internal inspection of wind turbine blades necessary?

Wind turbine blades are composite components subjected to cyclic bending, torsion and vibration loads over 20–25 years. Internal defects — delaminations, matrix cracks, fibre separations — are not visible from the outside and are not detected by superficial visual inspections. A wind turbine blade inspection robot enables complete internal diagnosis before the blade fails, reducing the risk of major failure and the cost of emergency replacement or repair by several times compared with planned intervention. What makes Circular Cold Light illumination different from standard LEDs?

Standard concentrated-LED systems produce an intense central light spot and shadow zones at the periphery of the field of view — problematic inside composite blades with absorbent walls and narrow geometry. The Jiutai-patented "Distributed Circular Cold Light" illumination distributes light uniformly across the entire circumference of the camera's field of view, eliminating shadow points and ensuring uniform visualisation of fine surface defects, including at the edges. Can the GT380 be used both for wind blades and for oil or gas pipelines?

Yes. The same GT380 wind turbine blade inspection robot also inspects oil and natural gas pipelines with diameters of 230–3500mm — applications with high degrees of internal corrosion where the PTZ camera with 10x zoom and anti-rollover ensures complete documentation. The interchangeable 110/150mm wheel sets allow adaptation to different diameters without replacing the base platform. What minimum and maximum diameter does the GT380 cover?

The GT380 inspects structures with an inner diameter between 230 mm and 3,500 mm (9"–138"). The 110mm wheels cover the lower range, while the 150mm wheels extend the crawler's capacity to larger-diameter structures. The 230–3500mm range fully covers commercial wind turbine blades (typical inner diameter 300–800mm at the base) and large-diameter oil and gas transport pipelines. How does the GT380 compare with the GT400Pro for wind blade inspection?

Both systems have anti-rollover and cover large diameters. The GT400Pro brings 4MP versus the GT380's 2MP and a standard laser, suited to precise dimensional documentation. The GT380 brings the patented Circular Cold Light illumination and the adjustable 1–25 m/min speed — an advantage for long wind blades where variable speed and uniform illumination on composite surfaces are critical. The choice depends on the required priority: 4MP resolution or circular illumination optimised for composites. Why Buy the GT380 Wind Turbine Blade Inspection Robot from UZINEX?
