ABSTRACT:
An apparatus for decelerating descending bodies includes a tubular arrangement vertically disposed or steeply inclined secured at its upper-end to an elevated location. The bodies to be transported are guided down through the tube which retards their movement. Within the wall of the tubular arrangement there is at least one extensible chamber filled with pressurized fluid and having associated with it pressure regulating means, which chamber serves to apply a retarding force to a descending body. The walls of the tubular arrangement are flexible and include a sleeve whereof the wall is non-extensible in the longitudinal and/or axial direction.
