Braking device, for example having eccentric element, for braking traveling body that can be displaced in guided manner along guide rail in displacement direction

The invention relates to a braking device (1) for braking a moving body (3) which can be displaced in a guided manner in a displacement direction (47) along a guide rail (5). The brake device (1) has a holder (17), a brake element (19), a preload element (21), a trigger element (23) and a hold-down element (25). The braking element (19) has a braking surface (31) directed towards the guide rail (5) and is held and supported on the holding part (17) in such a way that the braking element (19) can be displaced relative to the holding part (17) between a free operating position and a braking position, the braking surface (31) of the braking element (19) being laterally spaced apart from the guide rail (5) in the free operating position and the braking surface (31) of the braking element (19) being in the braking position. And the guide rail (5) is compressed along the side direction. The pre-tensioning element (21) is configured to, in the deactivated configuration, apply no force to the braking element (19) tha
