PROBLEM TO BE SOLVED: To improve the cleaning efficiency by facilitating insertion of a hose in a pipe to be cleaned, and smoothing torsion and rotation of the hose during the cleaning work. SOLUTION: In a high pressure cleaning vehicle, a water tank, a water pressure boosting device to highly pressurize the cleaning water in the water tank, and a hose reel mechanism 20 to wind and rewind a hose 21 to introduce the pressurized water to a pipe to be cleaned are mounted on a vehicle body frame 1. A boom 14 capable of turning, derricking and expanding/contracting is mounted on the vehicle body frame 1, and the hose reel mechanism 20 is turnably mounted on the boom 14 to move the hose reel mechanism 20 at any place in the longitudinal direction and right-to-left direction of the vehicle body. |
