As the outer spans move, the control rod rotates the cam plate toward the running micro switch.

As the outer spans move, the control rod rotates the cam plate toward the running micro switch. As the inner tower catches up to the outer tower, the cam plate rotates in the opposite direction until the run micro switch is disengaged - stopping the tower. This process is repeated as the machine walks around the field. RainTek supply good quality all kinds of tower box with below specifications and exclusive innovations:
