SOLUTION: A movable truck 5 is installed so as to be freely moved in the front and back directions by being guided by a horizontal fixed rail 3 fixed to bed 2 of a fire truck. A vertical movable rail 11 is installed so as to be freely moved in a vertical direction by being guided by a vertical fixed rail 9 erected at the rear part of the movable truck 5. A pump mounting base 15 for mounting the transportable fire pump 14 is fixed in a horizontal direction at the lower part of the vertical movable rail 11. The movable truck 5 is provided with a hydraulic cylinder 18 for elevating and lowering the pump mounting base 15, a hydraulic pump for supplying pressurized oil to the hydraulic cylinder 18 by the operation of an operation handle 19, an oil tank 22 for supplying the oil to the hydraulic pump and recovering the oil discharged from the hydraulic cylinder 18 at the time of contracting the hydraulic cylinder 18, a normally closed relief valve for opening a return path through which the oil returns to the oil tank 22 at the time of contracting the hydraulic cylinder 18, and a valve operator 25 for performing the operation of opening the relief valve.
