Live working device based on maneuverable traction device and using method

The invention discloses a live working device based on a maneuverable traction device and a using method, and relates to the field of high-voltage circuit overhauling. The live working device comprises two fixed pulleys, a control rope, a hanging basket, a track rope and a power control mechanism; one end of the track rope is fixedly connected to a cross arm right above an insulator string; the other end of the track rope is fixedly connected with the hanging basket; the two fixed pulleys are respectively fixed on the cross arm; the end part of the control rope respectively bypasses the two fixed pulleys; the hanging basket is fixedly connected with one end, close to the insulator string, of the control rope; the power control mechanism is fixedly connected with the other end of the control rope; and the power control mechanism is used for stretching the control rope. The live working device has the beneficial effects that winding and unwinding of the control rope are controlled by a maneuverable winch on the
