The utility model discloses a steel wire rope lubricator, which comprises a horizontally-arranged oil storage barrel, wherein two ends of the oil storage barrel are provided with sealing elements with steel wire holes; a fixed platform is arranged below the oil storage barrel; and the oil storage barrel is hinged with the fixed platform by a hinge structure. According to the steel wire rope lubricator disclosed by the utility model, the oil storage tank is connected with the fixed platform by the hinge structure, so that the oil storage barrel swings in a manner relative to the fixed platform under the acting force applied when the steel wire rope moves vertically. A mode that the oil storage barrel and a support frame are fixedly connected in the prior art is not adopted, and therefore the phenomenon that the oil storage barrel and the support frame are broken in the prior art is avoided.
