[0002] When the conventional straight arm truck crane is working, the working range thereof is mainly limited by the arm length and the position of the vehicle. The stretching mode of the straight arm is relatively fixed, and the crane can only perform hoisting operation within a certain angle range on both sides of the vehicle. For example, in some narrow construction sites or wharf operation scenes with limited space, the straight arm truck crane can not be able to hoist and transport goods to certain specific positions, because the vehicle can not be able to approach the target position, or the arm length can not be able to reach the target position even if it is stretched to the limit.
