The industry-leading NAVIC is JIREH's most powerful, all-encompassing, weld and corrosion scanning solution.

The NAVIC 2 - Base Crawler is a modular, motorized, steerable scanner designed to carry multiple attachments used in various scanning and inspection applications. This remotely operated scanning platform is capable of circumferential scans on diameters as small as 70 mm (2.75 in) OD.

Part ID: CXG023

Features

Motorized Driving and Steering

Variable drive speed and steering control.

Rugged

Designed to handle intense tasks and challenging environments (dust tight, watertight).

Corrosion Mapping

Effortlessly perform corrosion mapping with a variety of automated raster arms.

Weld Scanning

Various probe holder frame configurations allow for carrying between 2 and 6 probes during weld inspection.

Modular

Increased capability with pod separation, multiple encoders, accessory mounts and a handheld controller.

Many Accessories

Enhance the NAVIC's capability with optional accessories: battery powered laser guide, onboard camera, backpack, cable management, crawler removal system and motorized couplant pump.

Magnetic Wheels

Magnetic wheels provide the foundation for scan operations on ferrous surfaces

Low Profile Design

The NAVIC can circumnavigate pipes as small as 7 cm (2.75 in) OD while only requiring 7 cm (2.75 in) of radial clearance when low profile scanning is required.

Remote Control

Program scan and raster paths from up to 30 m (100 ft) away using the intuitive handheld remote control. The ergonomic handheld controller includes programming of raster patterns, drive paths and system diagnostics.

Warranty

JIREH backs the NAVIC system with a limited 3-year warranty.

Component Identification

Base Crawler

The powerful base crawler carries probe holder frames, raster arms and a multitude of accessories for the purposes of weld and corrosion inspection.

Integrated encoder

A spring-loaded encoder maintains surface contact on all various scan surface diameters. 

Magnetic Wheels

Powerful magnetic wheels ensure the crawler remains fixed to any ferrous surface.

Power Controller

Compatible with both North American and European power sources, the power controller connects the user instrument and handheld controller to the base crawler.

Umbilical

The backbone of communication between the power controller and the base crawler.

Handheld Controller

Containing the NAVIC operating system, the handheld controller joysticks control speed and steering of the base crawler while the intuitive touchscreen allows for more intricate raster path and drive programming.
