The invention discloses a hydraulic cable collecting-releasing apparatus. The hydraulic cable collecting-releasing apparatus comprises two cable movement tracks, a side wheel movement track, a brake apparatus and a hydraulic jack, wherein one side wheel movement track is formed at the back end part upwardly of the corresponding cable movement track; the direct back end of the corresponding cable movement track is connected with the hydraulic jack; the brake apparatus is arranged above the side wheel movement track; the back end of the brake apparatus is connected with the hydraulic rod of hydraulic jack through a brake connecting rod; each cable movement track adopts a long-strip U-shaped groove structure; five pairs of disc diameter limiting holes are formed in the rib plates on the two sides of the corresponding cable movement track; a rotary wheel can be put in each pair of disc diameter limiting holes; a movable wheel clamping groove is formed in the bottom of the front end of the corresponding cable movement track; and a moving wheel is put in the movable wheel clamping groove. The hydraulic cable collecting-releasing apparatus is more reasonable in structure, more convenient to operate, and capable of bringing great benefit to enterprises and creating a great loosen environment for power line relocation and power line reasonable reconstruction.
