GT102B pipe inspection crawler system — the reference portable solution for video inspection of pipes with diameters between 150 mm and 2.000 mm, with a range of 150 m in a single session. Equipped with a front PTZ camera with 10x optical zoom, continuous 360° rotation and 220° tilt, plus an independent rear camera, this pipe inspection crawler system transmits live dual high-definition images directly to the 10,1-inch IPS screen of the portable controller.
The low weight of the control unit (6 kg) and the portable electric cable reel make the GT102B a pipe inspection crawler system that is easy to move between sites, with no complicated logistics and no special vehicles. Where other systems require a fitted trailer, this pipe inspection crawler system is transported in the boot of a standard car. It is frequently chosen by teams inspecting petrochemical networks, gas pipes, municipal systems and industrial process pipes — wherever technical standards require HD documentation of internal defects. Key advantages of the GT102B pipe inspection crawler system
• Front PTZ camera with 10x optical zoom and infinite 360° rotation: The PTZ head allows optical close-up on any defect without repositioning the crawler, continuous rotation with no angle limit and 220° tilt, guaranteeing zero blind angles inside the pipe.
• Simultaneous dual front + rear camera: Unlike single-camera systems, this pipe inspection crawler system films simultaneously with the front PTZ camera and the rear camera, switchable from the controller with a single button, without losing footage or recording continuity.
• Adjustable macro focus for high-precision detail: The adjustable macro-focus technology allows clear viewing of very fine surface defects — microcracks, points of incipient corrosion, weld defects — regardless of the distance from the pipe wall.
• Real-time defect annotation: The operator marks and describes defects directly on the recording in real time, with the footage automatically displayed permanently on the screen — every defect documented precisely, located to the centimetre, ready to include in the report.
• Portable 10,1-inch IPS controller, 6 kg: The IPS screen with a full viewing angle and high brightness allows use outdoors, in direct sunlight, without a sun shade. The 6 kg weight makes the controller transportable with one hand from one manhole to the next.
• 150 m cable with portable electric reel: The electric reel deploys and retrieves the cable automatically, reducing operator fatigue on long sessions. The 150 m length fully covers the average section of a secondary municipal or industrial network.
• IP68 protection and corrosion resistance: The camera head and crawler body are IP68-sealed and anti-corrosion treated — resistant to immersion in wastewater, hydrocarbons, sludge and the aggressive chemical environments specific to petrochemical and industrial sewerage applications.
• Storage up to 1 TB and HDMI export: HD video, photos and inspection reports are stored on USB or internally (expandable to 1 TB) and exported via HDMI — fully archivable and ready to hand over to the client immediately after the session.

Applications — where the GT102B pipe inspection crawler system is used
A pipe inspection crawler system from the GT102B series is the standard choice of maintenance teams in the petrochemical, energy and gas distribution industries. Compatibility with diameters from 150 mm to 2.000 mm fully covers process pipes, distribution connections, industrial sewer columns and secondary municipal collectors — without requiring additional equipment for different diameter segments.
In municipal water and sewerage infrastructure, the GT102B pipe inspection crawler system is used for the pre-acceptance inspections of newly rehabilitated sections, for the periodic audits required by operating regulations and for the pre-rehabilitation assessments needed for EU funding documentation. The dual front/rear camera and real-time annotation allow complete identification and documentation of cracks, infiltrations, deformations and blockages without repeating the session.

The civil construction, HVAC installations, air separation and large industrial containers sectors use pipe inspection crawler systems for internal technical inspections of hard-to-access spaces, in accordance with international standards for non-destructive video pipe inspection. The portability of the GT102B makes it optimal for working in areas with no vehicle access or with limited support infrastructure. How it works — workflow with the GT102B
• Preparation and insertion into the pipe: The crawler is inserted through the manhole or the accessible end of the sections. The 6 kg portable controller is positioned on the edge of the manhole or on an improvised stand, without requiring a trailer or a support vehicle.
• Live control from the 10,1-inch IPS screen: The operator watches the simultaneous front/rear image in real time. Switching between the front PTZ camera and the rear camera is done with a single button, without stopping travel or losing footage.
• Zoom and precise defect documentation: When a defect is identified, the 10x optical zoom is activated for optimal close-up, the macro focus is adjusted for maximum clarity, and real-time annotation automatically marks the location and type of defect on the recording.
• Automatic cable retrieval: The portable electric reel retrieves the 150 m of cable automatically or manually, depending on the operator's preference, eliminating the effort of manual winding and reducing the risk of cable damage from uncontrolled tensioning.
• Report generation and export: At the end of the session, the complete inspection report — with HD video, marked photos, defect localization and footage — is exported via HDMI or saved to USB, ready to hand over to the client or archive in the network management system.
Frequently asked questions about the GT102B pipe inspection crawler system
What pipe diameters does the GT102B pipe inspection crawler system cover?
The GT102B is compatible with pipes ranging in diameter from 150 mm to 2.000 mm (6"–78"). This range covers secondary distribution networks, medium-diameter municipal collectors, industrial process pipes and large containers — without changing the base equipment or requiring additional accessories for different diameter ranges. How does the GT102B differ from the GT108 and the GTDR-200?
The GT102B is the portable pipe inspection crawler system in the Jiutai range — 6 kg controller, 150 m range, 150–2.000 mm diameter. The GT108 is the heavy municipal variant (300 m cable, 200–3.500 mm, 40 kg reel). The GTDR-200 is the solution for vertical and horizontal inspection of pipes from 100 mm, with a 210° panoramic camera. The choice depends on the dominant diameter and the support infrastructure available on site. How long is the cable and can it be extended?
The standard cable length is 150 m, sufficient for the average section of a secondary or industrial network. To order, the length can be customized according to the project specifications. The cable is deployed and retrieved by the portable electric reel, with no additional physical effort for the operator. What reports does this pipe inspection crawler system generate?
The system generates professional inspection reports with time stamping, continuous footage, localization of defects annotated in real time and associated HD photo/video captures. Export is done via HDMI or to USB — a format compatible with the standard requirements of public clients, ANAR operators and contractors working with EU funding. Is special training required to operate the GT102B system?
The portable controller interface is intuitive, with the main functions — zoom, camera switching, annotation, recording — accessible directly from the integrated keypad. No advanced technical training is required. The UZINEX team provides operator training on delivery, so that the pipe inspection crawler system is functional from the first day of use in the field.
