Plate type balance beam

A plate type balance beam comprises a beam body, an aperture type center hole, bosses and aperture type end holes. The beam body is the main part of the plate type balance beam and directly made of thick steel plates meeting the strength requirements, the aperture type center through hole is arranged in the center of the beam body, the aperture type end through holes are arranged in two ends of the beam body respectively, and the bosses are arranged at positions of the upper planes in the two ends of the beam body. The plate type balance beam is simple in integral structure, convenient in operation and use, fine in stability and high in reliability. The plate type balance beam has higher structural bearing capacity particularly, and is simple in process, low in cost and widely applicable to small and medium sized engineering machinery.
