Claims

[Scope of Claim for Utility Model Registration] An engine is installed on a chassis that is horizontally supported by front and rear wheels, and a blade mounting shaft that rotates under the rotational torque of the output shaft of the engine and a blade mounting shaft that is mounted on this mounting shaft. In a concrete cutter having a disk-shaped blade, the blade 6 is moved by the vertical movement means 25 consisting of the motor 26, the leader 27, and the guide body 28 to move the mounting body 35 of the blade mounting shaft 34 to this guide. The mounting body 35 of the blade mounting shaft 34 and the trolley 2 can be moved up and down while being guided by the body 28.
The upper fixed mounting body is connected by a universal telescopic shaft 38, and the blade 6 can be moved up and down by the vertical movement means 25 while keeping the front and rear wheels of the chassis in contact with the ground. A tilting means 45 consisting of a blade tilting bearing 23 and a motor 24 is attached to the lower part 29 of the blade 28, and the blade tilting means 45 moves the blade 6 to the left and right 12,
22, and when the concrete cutter is tilted, the universal telescoping shaft 38 expands, contracts and tilts, thereby making the blade 6 vertically movable and tiltable.
