A pantograph assembly configured to transfer electrical power from an overhead conductor to a machine is disclosed. The pantograph assembly may include a pantograph base detachably mounted to the machine, an articulated linkage assembly having a linkage assembly lower end operatively connected to the pantograph base and a linkage assembly upper end pivotally connected to the linkage assembly lower end, a collector rail assembly operatively connected to the linkage assembly upper end, and a stop member. The stop member may be connected to the pantograph base and engaging the articulated linkage assembly, or connected to the articulated linkage assembly and engaging the pantograph base, to prevent the articulated linkage assembly from being lowered toward the pantograph base below a predetermined down position or lower limit position. A latch assembly may be mounted on the pantograph base and operable to move between a latch locked position and a latch unlocked position.
