摘要

PURPOSE: To easily reduce noise, to dispense with the aligning operation of an agitator, to reduce the agitator to a small-size unit, and to facilitate the adjustment of the width of pavement. ;CONSTITUTION: An exciting unit 2 is made up of a vibration frame 4 to which one set of agitator 6 and a hydraulic motor 8 connected to the agitator 6 are fitted. A plurality of exciting units 2 are suspendedly mounted on a concrete finisher body through vibration-proof rubber member 10 for each unit. The output shaft of the hydraulic motor 8 is connected to the supporting shaft of the rotor of the agitator 6, and a cylindrical housing covering the rotor, the hydraulic motor 8, and the coupling are provided.;COPYRIGHT: (C)1996,JPO
