  • the brake does not act in a pressureless state, which is easier to align by the user.
  • the displacement force is limited, since at positively controlled displacement of the outer tube, that at least one braking element, although also on an inclined surface to Outside is pressed, but the radial force is ultimately limited by the friction and sliding conditions on the inner seal of the brake piston to the inner tube, so that from the time of sliding friction between the brake piston and inner tube no additional radial forces are transmitted to the standpipe.
  • the components of the braking or blocking device are connected to one another in a simple manner when the outer tube has at least one through opening which passes through a braking element, and if the brake element has on its facing the inner tube end or peripheral side which has a ramp on the brake piston acting inclined surface and with its opposite, outwardly facing end or peripheral side cooperates with a, the outer tube embracing standpipe.
