Abstract
Extended reach sluicer systems, devices, and methods for breaking up and retrieving chemical, radioactive, hazardous materials and/or other waste from storage tanks, with mechanical arms and nozzles which utilize fluid jets to break up and liquefy in-tank material. The invention can work with tanks having additional issues, such as but not limited to high temperature or low temperature conditions. An upper assembly attachable to a tank can control the transverse rotation of a vertical mast and with a lower end pivotally attached to a boom having a nozzle assembly attached to an outer end. The boom can telescopically retract and extend to different length positions by cables and pulleys. Controls with take-up mechanisms can elevate up and down or transverse left and right the nozzle assembly.
