JoystickJoystick listed as an aftermarket replacement for industrial forklift hydraulic and traction control assemblies. The joystick translates operator input into proportional commands for lift, tilt, and direction, and a failed unit drops a truck out of service immediately because the operator has no way to control the working hydraulics. fleet maintenance teams replace it when the operator reports erratic motion, dead-band at center, or a logged controller fault that points to the input device.
