A ground clamp system has been patented, comprising a movable jaw, a fixed jaw, a housing containing a piston, and a linear spring to close the conductor receiving gap between the jaws. The spring force required to compress the spring is in the range of 140 to 250 pounds force. The system also includes a hot stick connector and an electrically conductive member mounted onto the spring. The system allows for optimal spring force concentration and electrical connection with the conductor clamped between the jaws, with serrations or teeth formed on the facing surfaces of the jaws.
Furthermore, the patented system includes a grounding clamp system with a hot stick and a hook retractably mounted on the hot stick. The system allows for easy opening and closing of the gap between the jaws to place a conductor and clamp it securely. The method of using the system involves manipulating the hot stick to position the ground clamp head, capturing the conductor, and closing the jaws onto the conductor. The system's design ensures efficient spring force concentration and electrical connection with the conductor, providing a reliable grounding solution for linemen in the field.
