The invention discloses a sideway roller type propeller tipper and belongs to the technical field of mechanical manufacturing. The whole tipper consists of a turning wheel, adjustable finials, wheel sets, turning wheel sets, a sideway trolley, a U-shaped supporting rack, a track and a turning drive mechanism. The shaftless turning wheel is used as a core part of a turning device; the turning wheel is provided with a horizontal opening; and the upper part and the lower part of the opening are symmetrically distributed with two sets of the adjustable finials. The sideway trolley is provided with four wheel sets, four turning wheel sets and the turning drive mechanism, wherein the wheel set is used as a sideway walking device; and the turning wheel set is used as a supporting and turning drive device of the turning wheel. The U-shaped supporting rack has a fixed supporting structure for putting a propeller before and after the turning. The U-shaped opening allows the turning wheel and the U-shaped supporting rack to complete the butt joint of the propeller. The sideway roller type propeller tipper has the advantages of compact structure, light weight, reasonable stress, simple auxiliary process, safe and high-efficient turning operation and small turning drive power.
