ABSTRACT:
A piping structure of a crawler driving hydraulic motor able to reduce a reduction in strength of a vehicle body frame and shorten the exposure length of a hydraulic piping in the exterior of the vehicle body frame, and reduce a damage opportunity due to an external obstacle, etc. Therefore, the hydraulic piping is connected from a hydraulic pump arranged within the vehicle body frame to left-hand and right-hand crawler driving hydraulic motors respectively attached to one-end sides of left-hand and right-hand crawler track frames arranged on left-hand and right-hand outsides of the vehicle body frame. The hydraulic piping extends through a frame rear wall constituting the vehicle body frame, and is taken out to the exterior of the vehicle body frame, and is connected to the left-hand and right-hand crawler driving hydraulic motors.
