The present invention relates to a lateral reinforcement type boom for a ladder truck, the boom comprising: a main boom (11) which is rotatably installed in a vehicle (10) and extends such that multistage protraction/retraction is possible; and auxiliary booms (13) which are coupled to each of opposite side surfaces in a transverse direction of the main boom (11) such that multistage protraction/retraction is possible, therefore since the main boom can be reinforced by the auxiliary boom at opposite sides, the overall bending strength of the boom and the strength against lateral load can be further improved. In addition, an extension ladder which is mounted on the lower end of the main boom to be relatively movable along the main boom so as to extend to the ground when the ladder truck is in operation so that a carriage of the ladder truck can descend to the ground, and thus the extension ladder is coupled to an upper surface on a lower end of the main boom in which the auxiliary booms for reinforcement are coupled to opposite side surface thereof such that the extension ladder can relatively move to extend to the ground. Therefore, the carriage moving on the boom is lowered close to the ground by using the extension ladder so that luggage can be easily moved up and down to the carriage.
