PTT unit
Trim-up and tilt-up function
When the PTT switch is pressed to “UP,” the PTT motor operates the gear pump and fluid pressure
is generated. As a result, the fluid pressure pushes the up-shuttle piston, enters the trim cylinder
and tilt cylinder lower chambers through the up-main valve, and then pushes the trim ram and tilt
ram upward.
In addition, the fluid pushes the down-shuttle piston, opens the down-main valve, and returns from
the tilt cylinder upper chamber to the gear pump.
After the trim ram has extended completely, the tilt ram operates to tilt up.
