The invention relates to a swing arm mechanism of a crawler and particularly relates to a crawler belt swing arm and a tensioning device of the crawler belt swing arm. The crawler belt swing arm comprises an inside bull wheel, a crawler belt, an outside bull wheel, a swing arm, an outside pony wheel, an inside pony wheel and the tensioning device; the tensioning device is mainly composed of a tensioning strip, a swing bearing pedestal, a swing supporting shaft and tensioning bolts; a U-shaped groove is formed in one end of the swing arm; the direction of a notch of the U-shaped groove is outward along the direction of the main shaft of the swing arm; the tensioning strip is installed on the swing arm and is close to the U-shaped groove; the tensioning bolts are connected into screw holes in the tensioning strip through threads. According to the invention, the meshing degree between the crawler belt and a belt wheel is changed, and great convenience is brought to the installation and detachment of the crawler belt.
