Abstract: A smart clamp load handler configured for controlling movement of its clamp arms and force applied by its clamp arms by changing positions of one or more solenoid operated valves to control hydraulic fluid flow to and from clamp arm actuators, based on pressure measurements from one or more pressure sensors.

Abstract: 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.
