PURPOSE: To drive a hose wind-up section by utilizing a prime mover of a prime moving pump section and automatically and efficiently execute wind-up, etc., of hoses by separating the prime moving pump section and the hose wind-up section as separate units and disposing a driving power transmission device from the prime moving pump section to the hose wind-up section.

CONSTITUTION: The prime moving pump section 1 which consists of the prime mover 4, a pump 5, the water suction hose 6 and the water discharge hose 7 and the hose wind-up section which consists of hose reels and aligning machine are separated as the separate units. The driving power transmission device from the prime moving pump section 1 to the hose wind-up section is disposed to drive the hose wind-up section by utilizing the prime mover 4 of the prime moving pump section 1. In the meantime, the driving power transmission device is constituted by assembling a connector 10 in common use as a speed change gear 9 to the take-off shaft part 8 of the pump 5 by means of a flange 11 and connecting a flexible shaft 12 to the output shaft of the speed change gear 9. On the other hand, the flexible shaft 12 may be connected via a pulley 14 to the output shaft of the prime mover 4. As a result, the wind-up, etc., of the hoses are automatically and efficiently executed.
