MARK I Lightweight Magnetic Crawler Vehicle

NDT International, Inc. offers a small, lightweight crawler vehicle for ultrasonic thickness measurement surveys of steel tanks.If you need something easy to use and inexpensive consider our MARK I Crawler vehicle.

This is a 3-wheeled vehicle that has been designed to be manipulated (raised and lowered) by hand using an extension pole with pulley system (not supplied by NDT) or just a rope with a top-side assistant. The vehicle includes a High Gain 1/2″ diameter 5 MHz spring-loaded dual transducer with an intergal water line. It can be attached to many different ultrasonic testing instruments as long as it the can drive the ultrasonic signal through the 50 foot long dual coaxial cable.

The Mark I Crawler Vehicle measures only 8 1/2″ L x 6″ W x 4 1/2″ H and weighs only 3 lbs with the transducer.

It includes a plastic shim set for adjusting the clearance of the magnets attached to the underside of the nylon chassis. These magnets provide a holding force of 8 lbs. at a 1/8″ clearance from the steel surface. Also included is a 50 foot long Transducer and Couplant Line Cable Assembly and a hand pumped, 2 gallon capacity Couplant Supply Tank.
