Alternately-moving dual-rail ladder

The utility model belongs to the field of sports equipment and relates to an alternately-moving dual-rail ladder. The alternately-moving dual-rail ladder is characterized in that anti-skid rubber pads (7) are arranged on the upper surfaces in four sliding sleeves; the four sliding sleeves sleeve four longitudinal flat tubes (2); two ends of the four longitudinal flat tubes are connected with two transverse flat tubes (6) in a welding mode; the lower parts of end heads of the two transverse flat tube are connected to upper end faces of four upright posts (5) in the welding mode; lower ends of the four upright posts are arranged on the ground (1); outer ends of two circular cross bars (4) are respectively connected with inner surfaces of the four sliding sleeves in the welding mode. Compared with the currently-used fixed rod spacing distance ladder, the alternately-moving dual-rail ladder has the benefits that when the two cross bars are respectively held with two hands of a trainee to alternately move the alternately-moving dual-rail ladder forwards, the spacing distance between the two rods is random, and the defects that the requirement on the spacing distance among different rods cannot be met by the spacing distance between the fixed rods of an existing ladder is avoided.
