PURPOSE: A transport apparatus is provided to rapidly mount obstacles by using an assist foot which is provided with driving force from a drive motor. CONSTITUTION: A transport apparatus comprises a pair of steering wheels, a pair of drive wheels, a pair of drive motors, a reducer assembly(170), a drive shaft, an assisting foot assembly, and a bevel gear assembly. A pair of steering wheels is arranged in the lower part of the front of a frame. A pair of drive wheels is provided with driving force from the drive shaft and moves the frame backward and forward. The drive motor generates driving force moving the drive wheels backward and forward. The reducer assembly comprises a worm gear and a worm wheel gear. The drive shaft rotates the drive wheel. In the assisting foot assembly, an assisting foot lifts the drive wheel in the vertical direction when the drive wheels meet an obstacle. The bevel gear assembly transfers motion between the drive shaft and an assist shaft. |
