3.7 PILOT JOYSTICK
Pilot joystick is mounted on the right side of seat
and used to control the working system. The right
figure shows three-link pilot valve and the
ordinary two-link pilot valve has no small right
handle.
The left and right movements of joystick are used
to control the moving direction of the bucket. The
front and rear movements of joystick are used to
control the moving direction of the lift arm. Both
joysticks are normally in a middle position. When
the engine is working, by pushing forwards the
pilot joystick, the lift arm will be lowered; by
pulling backwards the pilot joystick, the lift arm
will be raised; by pushing rightward the pilot
joystick, the bucket will dump; by pulling leftward
the pilot joystick, the lift arm will roll back. Slightly
moving forward or backward the two joysticks can
control the opening of main valve. The opening of
throttle valve of diesel engine can also be
controlled. The two kinds of controlling ensure the
exact movement position and speed of working
device.
The pilot joystick has the floating function:
By pushing the pilot joystick to the most front position, it will be attracted by the lift arm
floating magnet (the lift arm joystick will not return to neutral position even after the
operator takes his hand off it), and the lift arm will be brought to the floating status. To
terminate the lift arm floating status, pull back the lift arm joystick to the neutral position.
To have the bucket scrape materials, push the lift arm joystick to the lift arm floating
position, and the bucket will be raised or lowered according to road surface shape but not
contact thus protect the road surface.
