To provide a loading-type truck crane capable of improving safety.SOLUTION: The loading-type truck crane comprises: an outrigger device including right and left outriggers expandable/contractible in a vehicle width direction of a vehicle and mounted on the vehicle; a boom rotatably mounted on the vehicle; and a rotation angle calculation device for calculating a boom limit rotation angle on the basis of the jack reactive force of a reverse overturn outrigger which is, of the right and left outriggers, an outrigger disposed oppositely to the boom in the vehicle width direction in a state where the boom is rotated from a reference position.SELECTED DRAWING: Figure 3

    【課題】安全性を向上できる積載形トラッククレーンを提供する。【解決手段】積載側クレーンは、車両に搭載され、車両の車幅方向に伸縮可能な右側アウトリガ及び左側アウトリガを含むアウトリガ装置と、車両に旋回可能に搭載されたブームと、ブームが基準位置から旋回した状態において、右側アウトリガ及び左側アウトリガのうち、車幅方向においてブームと反対側に配置されたアウトリガである反転倒側アウトリガのジャッキ反力に基づいて、ブームの限界旋回角を求める旋回角算出装置と、を備える。【選択図】図3
