Abstract There is provided a novel high altitude breaking apparatus for fire fighting comprising a high altitude working vehicle for fire fighting having a breaking spear slidably mounted for stick-out and retraction on the tower top of said vehicle the arrangement being such that the tower top is brought close to a closed glass wall of a burning building with the breaking spear held in its retracted position and the breaking spear is forcefully stuck out from within its shooting range by the action of spring force to smash the glass wall to provide for spraying water into the room to extinguish the fire and for the rescue of the persons shut up in the room. The breaking spear is mounted for angle adjustment on the tower top so that it can be directed at right angles to the glass wall to ensure that the spear will positively and accurately break the glass wall. Further, the breaking spear is safely remotely controlled from the vehicle. Other merits and details of the construction will appear as the description proceeds.
