The invention relates to a lifting cylinder (100) for actuating a magnetic rail brake (1), comprising a cylinder body (10), in which a piston (11) is movable in a stroke axis (12), wherein an operating pressure chamber (13) in the cylinder body (10) to which a pressurizing means can be applied can be movably delimited by the piston (11), and wherein a piston rod (14) is attached to the piston (11) which can be connected by a free end to the magnetic rail brake (1), and wherein the piston (11) can travel from a position (I) raising the magnetic rail brake (1) to a position (II) lowering the magnetic rail brake (1) via application of pressure to the operating pressure chamber (13), wherein the lifting cylinder according to the invention ensures the maintaining of a holding force for holding the magnetic rail brake in the raised position, wherein in particular according to the invention holding means (15) are introduced in the cylinder body (10) via which the piston (11) can be held in the position (I) raising the magnetic rail brake in a positive-locking manner. |
