This video shows a highly dynamic, hydraulically controllable spray cannon used to clean tanks like in the oil-, gas or chemical industry. An explosion proof camera and ex-proof headlamp are fixed on the spray lance and can be moved along two different axes. This means that every part of a tank can be cleaned from inside — unmanned. The camera and headlamp serve as the “eyes” of the cleaning robot and the operator.
The equipment is obviously used under extreme conditions. The camera, fixed to the spray lance, must endure vibrations from the hydraulic drive, chemicals, changing temperatures, gases and humidity.
