IPC: E02F9/24
Filed: 1990-11-29
Abstract: PURPOSE:To automatically limit the height of a boom by providing an electromagnetic switching valve between a boom oscillating cylinder and a cylinder control valve, and disposing an on/off switch for operating the switching valve and a boom angle detecting switch in a series in an electric circuit from a power supply of the electromagnetic switching valve. CONSTITUTION:A cam piece 21 for operating a limit switch 20 is fitted to a boom 5 by a bolt 23 in such a manner as to freely change the position thereof, and the boom height detecting position is changed by varying the fitting position. When an on/off switch 19 is turned on, and the boom 5 is raised to a designated position, the cam piece 21 pushes a contact 22 of the limit switch (angle detecting switch) 20 to turn off the limit switch 20, and an electromagnetic switching valve keeps off-state, so that the boom 5 is raised. When the boom is raised more than a designated position, the contact 22 is separated from the cam piece 21 to turn on the limit switch 20 and turn on the electromagnetic switching valve, so that the supply of operating oil to the cylinder 7 is cut off to stop raising the boom 5. Thus, the height of the boom can be limited.
