A smart clamp load handler system configured for controlling a clamp and preventing over-clamping. The system having a first actuator coupled to a first clamp arm and a second actuator coupled to a second clamp arm, an actuator control valve configured to control flow of hydraulic fluid to the actuators, and an electrical controller configured for signaling the actuator control valve when compressing a load. In one embodiment, the electrical controller is configured for determining when to stop the closing of the clamp arms based on a series of first and second actuator position measurements, and a series of base-side and rod-side pressure measurements, then signaling the actuator control valve to stop the closing of the clamp arms.
