A washer system mounted on a skid, may be placed on a chassis with an aerial platform or with a remote controlled hydraulically operated nozzle and mounted on a telescoping boom. This nozzle has the ability to move both vertically and horizontally, giving it a very good range of motion. The main use for this type of washer is on EHV (extra high voltage) transmission lines. Generally these washers have controls at the base of the boom. With washers on an aerial platform, control stations are provided at the base of the boom along with one on the platform to allow the user to wash manually.
