Preliminary results on the development of a teleoperated compact trolley for live-line working

A new teleoperated trolley for live-line operations in under development at Hydro-Quebec´s Research Institute (IREQ). This very compact and lightweight trolley is part of the development of an innovative method for de-icing conductors and overhead ground wires. Many live-line applications have since been identified. Indeed, the second phase of the development of a teleoperated device for cleaning live-line conductors in South America should begin at the end of the year. A prototype of a live-line inspection vehicle with a remotely operated camera and other instruments also uses the trolley as its mobile platform. Another application for the trolley is the replacement of overhead ground wire with OPGW (or simply with a new ground wire), using the cradle block stringing method, which method needs a high traction force trolley. The design of the trolley uses state-of-the-art technologies, resulting in a very performing device that enables the development of new live-line
