The lifting equipment has a supporting part, plate 1, a lifting part, base 40, a movable part, rod 10, a lifting mechanism, motor 15 and limiting rod 24 and a winding mechanism connected to steel rope 23. One side of the supporting part has rotating parts, plates 2, and a rotating portion, rod 4, between the two rotating parts. A wire reeling part, rod 5, is fixedly arranged outside the rotating portion whilst a traction part, rope 6, is wound around the outside of the wire reeling part, and the bottom end of the traction part is connected to the lifting part. The traction part is externally provided with a connecting part, block 8, and the sidewall of the connecting part is provided with a fixing part, block 9, which is driven into the mine wall when the steel rope is tightened pulling transmission parts 7 downwardly. This forms a ladder structure using rods 10.
