を特徴とするクレーン車の自動変速装置。 The crane truck is equipped with a mechanism in which the driving torque of the internal combustion engine is constantly transmitted to either the front wheels or the rear wheels, and can be selectively transmitted to the other wheel by means of a torque transmission switching device, and the driving torque is at least set to a low gear. In an automatic transmission of a gear transmission having a high-speed gear, the gear selection means outputs a gear change signal according to the gear selected by a gear shift operation by an operator; and the gear of the gear selection means. and a switching drive means for switching and driving the gear transmission to a selected gear position in response to a selection signal, and the switching driving means is provided with a gear change signal for switching to a low gear position from the gear selection means. When,
An automatic transmission device for a crane truck, wherein the gear transmission device is switched to a selected low speed gear after transmission of the drive torque to the other wheel is established by the torque transmission switching device.
