Also known as drive cables or remote controls, winders are the manual mechanical systems used to push the radioactive source out of the projector and into the guide tube for exposure. These units allow technicians to operate the equipment from a safe distance, maintaining the “ALARA” (As Low As Reasonably Achievable) safety principle. Our selection features rugged, ergonomic Manual Hand Cranks equipped with high-tensile Drive Cables and gearboxes designed for smooth, jam-free operation. Built to handle the grit and grime of field environments like pipelines and refineries, these winders ensure precise source positioning and reliable retraction every time.
