Abstract
An improved apparatus and/or method for safely lifting a load along a lift axis are provided, through utilization of an automatic lockout arrangement operatively connected between the point of application of a lifting force and a motorized clamping arrangement for grasping the load. The automatic lockout arrangement precludes electrical power from being applied to open the system when the lifting force being applied to the automatic lockout arrangement has reached a predetermined lockout value.
