The present invention relates to a block single-pole live crossing frame. The crossing frame is symmetrically erected at two radical sides of a crossed electric power circuit, a wire block is connected between the top ends of the two crossing frames, the two ends of the wire block are connected with bearing ropes, the bearing ropes cross a crossing net and then are connected with ground anchors fixed on the ground, the concrete structure of the crossing frame comprises main holding poles, cantilever beams and skyward pulleys, the main holding poles are formed by a plurality of coaxially overlapped and fixedly arranged rectangular frame bodies, the two cantilever beams are symmetrically and fixedly arranged at two transverse sides of the upper ends of the main holding poles, the upper ends of the cantilever beams and the top ends of the main holding poles are levelled, and three sets of the skyward pulleys are uniformly distributed at the upper end faces of the cantilever beams at the transverse intervals.
