The invention discloses a manual type hoisting device. A pair of front supporting columns and a pair of rear supporting columns are hinged to the front end and the rear end of a bearing plate correspondingly, wherein the lower ends of the front supporting columns and the lower ends of the rear supporting columns are hinged to a base; an H-shaped support is fixedly arranged in the middle of the front end of the base and is welded and fixed to lower fixing angle steel of the base through an inclined supporting beam and upper fixing angle steel; a middle cross beam is arranged between the front supporting columns; a screw fixing base is arranged in the middle of the middle cross beam; a screw is arranged at an opening in the upper portion of the H-shaped support; a handle installing base, a bearing and a screw fixing sleeve are coaxially arranged on the outer wall of the screw; handles are symmetrically arranged at the two ends of the handle installing base; the end portion of the handleinstalling base is fixed to the bearing; the bearing is arranged at the upper end of the screw fixing sleeve in a matched manner; installing columns are symmetrically arranged at the two ends of the screw fixing sleeve; and the tail end of the screw is arranged on the screw fixing base through a bolt assembly. The manual type hoisting device is simple in structure, low in cost and convenient to produce and maintain; and the controllability of the hoisting stroke is greatly enhanced.
