Gantry systems mount the scanning head on an overhead bridge that travels across a fixed part — ideal when the part is too large, too oddly shaped, or too heavy to move through an immersion tank. SDI's gantry line spans squirter (water-column) delivery for open-shop floors to fully enclosed through-transmission configurations for repeatable production environments.
Seven-Axis Gantry Through-Transmission System
SDI's flagship gantry platform. Seven axes of motion follow complex part geometry with squirter-column water delivery, eliminating the need to submerge the part. Built for aerospace composite panels and large structural assemblies.
| Configuration | 7-axis, squirter through-transmission |
| Delivery | Water-column squirter |
| Typical use | Aerospace composite panels |
Dual-Bridge Gantry 3D Scanning System
Two independent bridges scan simultaneously across a shared rail system — doubling throughput on high-volume production runs without doubling floor space.
| Configuration | Dual-bridge, shared rail |
| Scanning | 3D curve-following |
| Typical use | High-volume production inspection |
Delta X Gantry Through-Transmission 3D Scanning System
A large-scale gantry platform for high-volume turbine and rotational component inspection, with a rotating turntable integrated directly into the scan envelope for curved and contoured aerospace parts.
| Configuration | Delta X gantry, through-transmission |
| Integrated turntable | Yes, for rotational parts |
| Typical use | Turbine components, large rotational parts |
Delta X Gantry Through-Transmission 3D Scanning System
A high-performance 3D curve-scanning UT system for both through-transmission and pulse-echo testing of composites and bonded structures. The Delta X drive bridge follows complex curves in any orientation — built for aircraft control surfaces, wings, doors, and highly contoured fuselage and cabin components.
Optional simultaneous dual-channel through-transmission and pulse-echo delivers four data files from a single scan. All motion control, drive, and instrumentation components are designed and manufactured in-house by SDI.
| Configuration | Delta X gantry, 3D curve scanning |
| Scan speed | Up to 35 in/sec |
| Dynamic range | 130 dB |
| Distance amplitude correction | 40 dB |
| Modes | Through-transmission & pulse-echo, simultaneous dual-channel option |
| Motion control | SDI-1830 MasterScan |
| Acquisition | SDI-WinScan multi-tasking package |
| Typical use | Aircraft control surfaces, wings, doors, contoured fuselage/cabin components |
