The invention discloses a striding type hand truck which comprises a frame-type bottom plate and a push / pull handle, wherein a telescopic striding bridge, a hydraulic transmission device, a retractable roller and a sliding clamp wheel frame are mounted on the frame-type bottom plate and the push-pull handle. The telescopic striding bridge comprises a drive system, a telescopic bridge frame and a lifting support leg; the retractable roller comprises a wheel retraction curved frame, a pull rope guide wheel and a wheel retraction gear; and the sliding clamp wheel frame comprises a frame-type sliding frame and a clamp gear. The striding type hand truck disclosed by the invention has a small volume and light weight, and can conveniently carry equipment in an overhauling site in which the spaceis limited and the mechanical machinery can hardly function; and in the case of a pipeline higher than the ground or a ditch lower than the ground in the carrying process, an operator can control thetruck to carry the equipment and stably cross over the pipeline or ditch by simply rotating a crank, an oil conveying pressure rod and a gearshift handle. Therefore, the striding type hand truck has a reasonable structure, and is convenient to use and applicable to the plants, towers or mines.
Description
technical field [0001] The invention belongs to a transport tool, in particular to a striding-type hand-push transport vehicle that can also run across pipelines or ditches while carrying heavy objects. Background technique [0002] Trolleys are widely used by maintenance workers due to their advantages of small size, light weight, convenient operation, and convenient operation in some maintenance sites such as workshops, under towers or mines where space is limited and motorized equipment is difficult to function. , Motors, pressurized pumps and reducers and other small equipment that exceed the capacity of human handling are transported to the machine repair workshop for repair, or the repaired small equipment is transported from the machine repair workshop to the installation site. However, water pipes, oil pipes and various channels higher or lower than the ground are often encountered on the ground of workshops, towers and mines, which hinders the normal handling of equ...
