The invention relates to a method and a climbing device (10) for lowering a climbing rail, i.e. for climbing downwards. In the method, the climbing rail, which is placed on a climbing head (18) by means of an upper protrusion, is lowered in that a climbing cylinder (20) is retracted. In particular, the climbing cylinder can be spaced from the climbing rail by completely retracting the climbing cylinder (20) at the upper end by means of a distancing device (34) prior to extending the climbing cylinder (20) again. Thus, the climbing cylinder (20) can be extended again without the climbing rail engaging or hooking below the climbing head (18) at the now central protrusion in that the distancing device (34) moves the climbing head (18) around the central protrusion. The distancing device (34) is activated in the retracted state of the climbing cylinder (20) in order to bypass a protrusion of the climbing rail and is deactivated in the extended state of the climbing cylinder in order to engage below a protrusion of the climbing rail (20) via a hook (22) of the climbing head (18). The climbing cylinder (20) preferably stands on a climbing shoe at the lower end, the catch of said climbing shoe being directly or indirectly releasable and blockable via a mechanical actuation means. The catch of the climbing shoe can be held in a reversibly releasable manner alternatively or in addition thereto by a blocking device in the form of a toggle lever joint and/or a push/push mechanism. Preferably, a lever is provided that can be actuated by a protrusion in order to extend the catch again, which is actuated by a protrusion.

A climbing device is proposed having at least one climbing rail (14) for adjusting and/or climbing a scaffolding and/or a formwork and/or a platform, at least one climbing shoe (15, 16) being arranged on the climbing rail (14), at least one hydraulic cylinder (2) comprising at least one drive piston (10), arranged in a cylinder housing (12), and having a hydraulic fluid being provided for raising the climbing shoe (15, 16) and/or the climbing rail (14) and/or the scaffolding and/or the formwork and/or the platform, which at least partially avoids or at least reduces the disadvantages of the prior art. According to the invention this is achieved in that the hydraulic cylinder (2) is embodied as a hydraulic unit (1), the hydraulic unit (1) comprising at least one hydraulic tank (5) for storing hydraulic fluid, an electric motor (3) and a hydraulic pump (4) driven by the electric motor (3) for pressurizing the hydraulic fluid.
