Aolong X-Ray Multi-Function Automated Positioning Trolley

Overview

The Aolong X-Ray Multi-Function Automated Positioning Trolley is an engineered solution for precision radiographic positioning in industrial non-destructive testing (NDT) environments. Designed to integrate seamlessly with portable X-ray generators—regardless of manufacturer or beam energy range (up to 320 kV)—this trolley implements a four-degree-of-freedom (4-DOF) electromechanical positioning system. Its core functionality relies on synchronized linear actuation (vertical lift, horizontal traverse, lateral shift) combined with motorized rotational articulation of the X-ray tube head (±90° azimuthal rotation). This architecture enables reproducible geometric alignment between radiation source, test object, and imaging detector—critical for achieving consistent geometric unsharpness (U_g) and minimizing parallax error in weld inspection, castings evaluation, and composite material assessment per ASTM E94/E1742 and ISO 17636-2 requirements.

Key Features

• Two standardized height configurations: 3-meter and 5-meter maximum vertical reach—engineered to accommodate both confined indoor workspaces and large-scale outdoor structural inspections (e.g., pipeline girth welds, wind turbine tower sections).
• Four-axis coordinated motion control: Independent servo-driven Z-axis lift, X-axis longitudinal translation, Y-axis lateral offset, and C-axis rotational positioning of the X-ray tube assembly—each axis featuring absolute position feedback via optical encoders.
• Universal mounting interface compliant with ISO 10962:2017 mechanical coupling specifications—ensuring mechanical and electrical interoperability with major portable X-ray systems including YXLON, Comet, Nikon Metrology, and domestic equivalents.
• Integrated human-machine interface (HMI) with touch-enabled control panel supporting pre-programmed inspection sequences, manual jog mode, and real-time positional telemetry (coordinates, angular orientation, load status).
• Fail-safe safety architecture incorporating dual-channel emergency stop circuits, torque-limiting actuators, and radiation interlock compatibility (via dry-contact input for shutter synchronization).

Sample Compatibility & Compliance

The trolley supports inspection of ferrous and non-ferrous components ranging from small machined parts (150 mm steel equivalent). Its load capacity (≥25 kg at full extension) accommodates most commercial portable X-ray tubes and collimator assemblies. Radiation safety compliance follows GB/T 18871-2002 (equivalent to IAEA Safety Standards Series No. GSR Part 3), with structural design validated for static and dynamic loads per ISO 12100:2012. Electromagnetic compatibility meets IEC 61000-6-4 (industrial environment immunity) and IEC 61000-6-3 (emission limits). Optional integration with radiation area monitors enables automated beam inhibition when personnel proximity thresholds are exceeded.

Software & Data Management

Positioning parameters—including source-to-object distance (SOD), source-to-detector distance (SDD), and tube angle—are exportable as CSV or XML files for traceability in QA/QC documentation. The onboard controller logs all motion events with timestamps and operator ID (when network-authenticated), satisfying audit requirements under ISO 9001:2015 Clause 8.5.2 and ASME BPVC Section V, Article 2. Firmware updates are delivered via secure USB or Ethernet (TLS 1.2 encrypted), with version history retained for regulatory review. No cloud dependency: all data remains on-device unless explicitly exported by authorized personnel.

Applications

• Field-based weld inspection of ASME B31.4/B31.8 pipelines using double-wall single-image (DWSI) or double-wall double-image (DWDI) techniques.
• Automated radiographic mapping of aerospace composite panels requiring precise angular incidence control to detect delamination and fiber misalignment.
• Periodic in-service inspection of railway axle forgings where repeatable geometry minimizes film/detector replacement frequency.
• Pre-commissioning verification of nuclear component penetrations under EN 13018-compliant procedures.
• Academic and training laboratory use for NDT methodology development, particularly in digital radiography (DR) and computed radiography (CR) parameter optimization.

FAQ

Does the trolley support remote operation via Ethernet or Wi-Fi?
Yes—standard Ethernet (RJ45) interface enables integration into facility-wide NDT control networks; Wi-Fi is not supported due to deterministic latency requirements for motion control.
Can it be used with both film and digital detectors?
Absolutely—the mechanical design imposes no constraints on detector type; compatibility is determined solely by the X-ray generator’s output spectrum and required exposure time.
Is radiation shielding integrated into the trolley structure?
No—shielding must be provided externally per site-specific ALARA analysis; the trolley itself contains no lead or tungsten components.
What maintenance intervals are recommended for the drive systems?
Lubrication of linear guides and gearboxes is required every 1,000 operational hours; encoder calibration verification is advised annually or after impact events.
Are spare parts and firmware updates available internationally?
Yes—Aolong maintains an authorized distributor network across Southeast Asia, the Middle East, and South America, with technical documentation available in English, Spanish, and Arabic.
