Abstract : A load limit system is provided for a linear actuator. An interface is attached to the linear actuator and is disposed between first and second spring assemblies. A first sensor senses a first amount of linear compression of the first spring assembly along a first direction. A second sensor senses a second amount of linear compression of the second spring assembly along a second direction. Movement of the linear actuator in the first direction ceases whenever the first amount of linear compression is sensed. Movement of the linear actuator in the second direction ceases whenever the second amount of linear compression is sensed.
