PURPOSE: To improve operability etc., by a hose guide, the rotation support of a hose reel, water and oil piping, and an operation box. CONSTITUTION: A swivel base 60 is installed swivelably on the load-carrying platform of a high pressure washing vehicle 1, and a hose reel mechanism 70 is attached laterally to the base 60 to be rotated by the first hydraulic driving means 51. The mechanism 70 is placed in a U-shaped arm 71 so that a reel 74 is rotated by the second hydraulic driving means 52, and a hose 31 with a nozzle 32 is wound up onto the reel 74. Piping is arranged so that high pressure water is supplied to the hose 31 from a high pressure water apparatus 10, and pressurized oil is supplied to the first and seconds hydraulic driving means 51, 52 from a hydraulic apparatus 40. A hose guide means 75 is attached to the hose feed side of the mechanism 70 to guide the hose 31 by reciprocating between one end of the hose winding range of the reel 74 and the other end by the second hydraulic driving means 52 when the reel 74 is rotated. |
