System consisting of a supporting guideway tube and movable supporting device for a suspended load

Abstract

The invention relates to a system comprising a supporting guideway tube ( 1 ) and a movable supporting device ( 16 ), wherein the supporting device ( 16 ) is arranged so that it can move along a longitudinal axis of the supporting guideway tube ( 1 ). The supporting device has a suspension device ( 22 ) which is suitable for carrying a suspended load. The suspension device ( 22 ) cooperates with a braking device ( 23 ) of the supporting device ( 16 ) in such a way that a braking action is exerted on the supporting device ( 16 ) according to the load, with respect to a movement of the supporting device ( 16 ) along the supporting guideway tube ( 1 ).
