The invention discloses a steel wire rope tension adjustment device. The steel wire rope tension adjustment device is detachably connected to one ends of the rope heads of steel wire ropes. Each rope head comprises a pull rod, an elastic piece, an elastic piece fixing base and a fixing piece. The steel wire rope tension adjustment device comprises hydraulic cylinders which are detachably connected to the rope heads of the steel wire ropes respectively. Each hydraulic cylinder comprises a plunger which is connected to the upper end of the corresponding pull rod in a threaded mode and a sleeve which is arranged on the upper portion of the corresponding pull rod in a sleeving mode and supported on the corresponding elastic piece fixing base, wherein the upper portion of the corresponding pull rod, the corresponding fixing piece and the plunger are arranged in the sleeve in a vertically movable mode. Each plunger and the corresponding sleeve are connected in a sealed mode, so that an inner cavity where hydraulic media can be injected is formed. Each sleeve is provided with an oil nozzle communicated with the corresponding inner cavity. A notch allowing the corresponding fixing piece to be exposed is formed in the side face of the lower portion of each sleeve. According to an elevator and the steel wire rope tension adjustment device of the elevator, the steel wire rope tension adjustment device is detachably installed and used on original rope heads, the tension of the multiple steel wire ropes can be adjusted at a time, manufacturing cost is low, using is quite convenient, and universality is higher.
