Abstract
A stair climbing wheelchair carrier having a carrier portion comprising a pair of endless belt crawlers, and a handle portion rotatably and detachably provided on the carrier. The handle portion is adapted to be rotated between an operating position and a wheelchair engaging position. The endless belt crawler has an oblique overhang portion which has a height higher than a usual height of a step of a staircase. The upper portion of endless belt crawlers are maintained by idlers in substantially horizontal position except the oblique overhang portion so that the wheelchair may be moved on the carrier portion and may be engaged with the handle portion at the wheelchair engaging position of the handle portion. The wheelchair is mounted on the carrier portion by rotating the handle portion to the operating position.
