The invention discloses a hand fork lifter capable of climbing stairs and aims at providing the hand fork lifter capable of climbing the stairs. The hand fork lifter is large in load, easy and convenient to operate, capable of being driven through manual work and stable and reliable in movement. The hand fork lifter comprises a support, a caterpillar band walking mechanism, a walking driving mechanism, a cargo loading mechanism, a cargo lifting mechanism and an auxiliary mechanism. The inverted-trapezoidal caterpillar band walking mechanism is adopted, the advantages that stress of a caterpillar band structure is even, the grounding pressure is small, vibration is little, noise is low, stair steps are not damaged, and large loads can be borne are effectively utilized. A labor saving pulley block is used for the loading and unloading function, and therefore weights can be lifted and moved through manpower. The hand fork lifter has the advantages of being simple in structure, reliable in performance and the like. In addition, the whole device is driven by labor force, and the requirements of underground mines or precise laboratories or other non-electric places can be met.
