Here, in order to change the length of the moving member 42 for moving the weight member 40, the installation space of the guide member 41 must be sufficiently secured in the weight control unit 40, and the inside of the frame unit 20 As shown in the drawing, since the installation space is structurally narrow due to other configurations, it is installed outside the frame unit 20 to avoid structural restrictions.

At this time, since the ladder boom 1 and the rotation cylinder 2 for the operation of the ladder boom 1 are installed on the outside adjacent to the frame unit 20, the guide member 41 of the weight control unit 40 is installed on the frame. As it is arranged spaced apart from the outside of the unit 20, it is possible to secure a sufficient installation space.

In particular, since the turntable balance adjusting device 100 of the fire ladder vehicle according to the present embodiment is tilted and rotated on the base portion 10 by the horizontal adjusting portion 30, interference may occur when placed adjacent to the frame portion 20. As possible, it may be installed spaced apart from a sufficient distance.

To this end, the weight control unit 40 according to the present embodiment may include a connection member 45 for separating the guide member 41 from the frame unit 20 .
