<p>The carriage (10) has guiding units i.e. hollow guide rolls (16), guiding the carriage on a rigid belay support e.g. inclined rail such as hollow metallic profile, in an integrated manner. An automatic locking unit is connected to an individual for automatically locking the carriage on the support during fall of the individual. The locking unit has an actuating lever (20) that is assembled by a spherical ball and socket joint with three degrees of freedom. The lever is received in a braking head (24) that is housed in a cavity (28) of a body.</p> |
