<p>The invention concerns a trolley designed to be used on a live power line. The trolley is equipped with three coplanar traction wheels spaced apart along a first longitudinal axis parallel to the live power line and thereabove. The trolley is also equipped with two coplanar pressure wheels spaced apart along a second longitudinal axis parallel to the line and thereabove. The trolley further comprises a traction motor for powering the traction wheels. Finally, the trolley includes a pressure system for maintaining the line pressed between the pressure wheels and the traction wheels, and a control system for controlling the motor. Said trolley has enhanced tractive power. Thus in operation, the trolley is driven along the line whatever the dimension thereof and/or climatic conditions. The invention also concerns a ice removing equipment mounted on the trolley for use on the live power line. The ice removing equipment comprises a clamp band adapted to be opened and closed around the live power line. The clamp band bears blades concentrically spaced and arranged to form a cone opening in the forward moving direction of the trolley.</p> |
