ABSTRACT:
A device for closing a pivotable wall of an animal squeeze chute utilizes a high torque electric motor that rotates a ratchet arm less than a half revolution about a drive shaft. An action arm pivotably associated with the ratchet arm engages the pivotable wall. When the motor is activated, the ratchet arm is quickly rotated to an extreme position where it is locked in place, and the pivotable wall is simultaneously forced to its closed position by the action arm. When the motor is deactivated and the ratchet arm unlocked, a counterweight restores the pivotable wall to its starting, open position.
