The JME MIDI 10" Pipeline Crawler is capable of driving a wide range of X-Ray generators and gamma head / actuator units, enabling internal panoramic Single Wall Single Image (SWSI) radiography to be carried out in pipe diameters from 10"-48".

Constructed using high grade materials to provide a good finish, superior corrosion resistance, easy maintenance and extended service life. Electronic circuitry utilising military specification components, ensuring reliability in harsh environments.

Powered by high-efficiency rechargeable sealed lead acid batteries.

Full remote control of travel, park and exposure modes from outside the pipeline using the JME 'Magnetope' or a low activity isotope.

Safety features include anti-runaway circuitry, and optional retrieval latching purpose built recovery vehicle and an automatic radio recovery system.

All backed by a 12 month warranty which covers all components and workmanship. (excluding radiography source)
