Abstract

PURPOSE: To prevent the occurrence of accident by intercepting the tranmission of vibration to crane-wire in the mechanism wherein hydraulic vibration cylinder is fixed on frame at the hanging piece side.
CONSTITUTION: By the continous revolution of the shaft 2 driven by the hydraulic motor, pressure oil from the pressure pump enters into the head side of the oil pressure cylinder thru hole H2 of the valve case 1, pump chamber, groove F1, and the oil at the rod side returns to the oil tank thru the 2ns port A2, etc., accordingly, hydraulic cylinder moves to one side. However, at the next moment, pressure oil from the pressure pump enters into the rod side of the oil pressure cylinder thru the groove F2, the oil pressure cylinder moves to the opposite side, and the repetition of the above motions generates vibration of the oil pressure cylinder. Accordingly, at the work using hanging wire, transmission of vibration to th crane-wire is intercepted and the fear of occurring accident is eliminated.
