Abstract

The invention relates to a method for disassembling springs for rail vehicles, wherein in a securing step (1) at least one first bearing device (2) of a bogie, in or on which at least one first spring (4) of the bogie is mounted, is secured against unintentional movement. It is proposed that in a lifting step (9) a support structure (11) of the bogie is lifted and in a release step (12) at least the first spring (4) is released from the at least first bearing device (2) by means of at least one spring disassembly tool (13) by applying a disassembly force generated by the at least first spring disassembly tool (13) against a contact force between the at least first spring (4) and the at least first bearing device (2), wherein the lifting step (9) is performed before or after the release step (12). This allows the first spring (4) to be released even under high contact forces (for example, due to corrosion, etc.).) are detached from the chassis.
