PURPOSE:To aim at the promotion of efficiency in operation so as to prevent a hose from twisting in time of drawing out the hose and its winding, by coiling one hose round on a hose reel alternately in the shape of the figure 8, in case of a mobile tank truck or the like. CONSTITUTION:A box 4 comprising a pump, a motor, a flow meter and an indicator is installed in the rear part of a tank 2, while two drumlike hose reels 7 and 8 are set up at the rear part of the box. Piping out of the tank 2 is connected to a hose 13 via a swivel joint 14, and the hose 13 is wound up on these reels 7 and 8 in 8-shaped form. And, a nozzle 15 is attached to the tip end of the hose 13. With this constitution, the hose 13 is rolled round on these reels 7 and 8 alternately in the reverse direction so that a problem of possible torsion is solved as a whole. In addition, since there are provided with two reels, double length of a hose can be wound up practically. |
