Claims

[Scope of utility model registration request]

A single crawler device in which arms 4 are horizontally rotatably attached to the sides from both ends of the lower frame, and rotate forward and backward on their own axis by driving energy supplied from the main body to the tips of the arms and a motor driven by the drive energy. The crawler device is supported at the center so that it can rotate freely in the longitudinal direction of the arm, and is also supported so that it can rotate in a horizontal plane relative to the arm, and the arm is equipped with a reaction force support device for vertical movement. A crawler crane characterized by being equipped with.
