Embodiment Construction

[0028] Such as figure 1 and figure 2 As shown, the stair-climbing manual forklift includes a bracket, a crawler traveling mechanism, a traveling driving mechanism, a cargo loading mechanism, a cargo lifting mechanism and an auxiliary mechanism.

[0029] Wherein, the support includes a chassis frame 2 and a door frame 7, the door frame 7 is fixed on one side of the chassis frame 2, and both are arranged in an L shape, and an armrest 19 is provided on the upper end of the door frame 7.

[0030] The crawler running mechanism is responsible for the traveling and climbing functions of the forklift that can go up the stairs manually. The crawler running mechanism is fixed on the chassis frame and has an inverted trapezoidal structure. Composition, driven wheel 1, driving wheel 5 and bearing wheel 4 are all installed on the chassis frame 2. Wherein, the driving wheel 5 is located at the rear of the chassis frame 2, the driven wheel 1 is located at the front, and the bearing wheels...

Abstract

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.

Description

technical field [0001] The invention relates to a manual forklift used in underground mines, precision laboratories or other non-electric places. Background technique [0002] Forklift is an important equipment in the logistics industry. It is a self-loading and unloading machine with a mast and a fork as the working device. It can be used for loading, unloading, and stacking of pieces of goods. It is small in size, light in weight, compact in structure, low in noise, low in cost, flexible in operation, and can work in a narrow space on the workplace. Therefore, forklifts are almost indispensable models in ports, railway stations, and warehouses. On the one hand, it is almost impossible for existing forklifts to transport on slopes or even stairs. The situation involving stairs transportation often requires manpower to complete, and the work efficiency is low. On the other hand, in some dangerous places, such as underground mines, or precision laboratories that require no ...
