MOVING METHOD OF MACHINE BODY IN CONCRETE

PURPOSE:To provide excellent mobility when a machine body is moved by means of wheels making rotational movement in concrete by reciprocating a breaking trowel for projecting parts on the surface of concrete, in the right and left directions in front of the machine body so as to move the body. CONSTITUTION:Vertically moving actuators 35 are held at four corners of an upper frame 9, and a first trowel part 11 is supported through the lower ends of the two front actuators 35. Further, a rear frame 36 is connected to the lower ends of the two rear actuators 35, and a second trowel part 12 and a third trowel part 13 are supported on the rear frame 36. Next, a first trowel 45 is reciprocated right and left, a second trowel 71 is moved up and down, a surplus heap discharge mechanism 73 is operated so as to vibrate a third trowel 85, and wheels 3, 5 are driven to rotate in concrete. Consequently, resistance due to concrete is reduced, and hence running by means of the wheels in concrete can be facilitated.
