Magnetic Crawler for Pipe, Elbow and Weld Inspection
The TRIPOD - Base Crawler is a remotely operated magnetic crawler for weld and corrosion inspection on ferrous pipes, elbows, vessels and tanks. Its three-wheel drive system supports longitudinal and circumferential travel on small-diameter pipes while maintaining stable probe positioning across curved surfaces.
The TRIPOD can carry probe holder frames for weld inspection, a motorized raster arm for corrosion mapping, or an actuated probe lift for 0° ultrasonic inspection. It can also travel over standard weld caps and lap joints, allowing multiple inspection applications to be completed with one crawler.
FEATURES
Tight-Radius Steering
The rear wheel rotates through 180°, allowing the crawler to pivot around either front wheel for tight directional changes.
High-Strength Magnetic Wheels
Maintain strong adhesion and traction on ferrous surfaces for controlled travel in horizontal, vertical, and inverted orientations.
Steering and Drive Control
Control TRIPOD steering, drive speed, and connected components directly from the handheld controller. The unit includes haptic feedback, a full-colour display, joystick control, and an integrated D-pad for precise, intuitive operation.
Handle
Simplifies lifting and transport, then removes when additional clearance or a lower operating profile is required.
Industrial-Grade Protection
Dust-tight and watertight sealing protects the crawler from water, couplant, dust, and debris in demanding inspection environments.
Cable Management
Organizes and protects cables and irrigation hoses to reduce snagging during operation.
BATTERY-POWERED OPERATION
Add the optional battery kit for portable power at the inspection site. Rechargeable batteries power the crawler and connected accessories for extended periods without the weight, noise, or setup required by a generator. (Sold separately)
RECON CAMERA SYSTEM
Add the optional RECON camera to view the inspection area and remotely drive and steer the TRIPOD in real time. (Sold separately)
Double Pivot Mount
Connects a motorized raster arm or probe holder frame to the TRIPOD through two male pivot mounts, with adjustment for positioning and alignment. (Sold separately)
WARRANTY AND SUPPORT
The TRIPOD includes a limited three-year warranty, with spare parts and in-house repair services available for continued product support.

Component Identification
Base Crawler
The TRIPOD base crawler uses a three-wheel magnetic drive system for steering and movement. Its wheel arrangement maintains stable positioning on curved surfaces while supporting both longitudinal and circumferential travel.
System Controller
The System Controller supplies power to the TRIPOD and connects the crawler umbilical, encoder cable, and handheld controller. It is compatible with an optional battery kit (sold separately).
Handheld Controller
The Handheld Controller operates and configures the TRIPOD with dual joysticks, a colour touchscreen, haptic feedback, and a D-pad. The joysticks control driving and steering, while the touchscreen and D-pad provide access to system settings and scan information.
Auxiliary Cable
The Auxiliary Cable connects the Handheld Controller to the System Controller and carries control and communication signals between them.
J300 Encoder Cable
The J300 Encoder Cable is a waterproof, 5 m (16.4 ft) cable that transmits encoder data from the TERAX to the inspection instrument.
Cable Management
The Cable Management sleeve protects and organizes probe cables, irrigation tubing, and other lines connected to the TRIPOD. Dual zippers provide access to the enclosed cables and tubing.
Umbilical
The Umbilical connects the TRIPOD crawler to the System Controller and carries network and control signals between them. Its heavy-duty construction supports use in demanding inspection environments.
