DESCENDING DEVICE WITH DIRECT DRIVE CENTRIFUGAL BRAKE

摘要

The present invention relates to a descending device for repeated braked descent of a load from an elevated structure. The descending device comprises a housing attachable to the elevated structure; a descent shaft rotatably attached to the housing; a centrifugal brake comprising a fixed part connected to the housing and a rotatable part connected to the descent shaft; and a rope configured for attachment of the load at two different load attachment portions being separated by a descent length of the rope. The descent shaft is directly connected to the rotatable part of the centrifugal brake such that one revolution of the descent shaft translates to one revolution of the rotatable part of the centrifugal brake; and the winding angle is at least 360°.

1. A descending device for repeated braked descent of a load from an elevated structure, said descending device comprising:
a housing attachable to said elevated structure; a descent shaft rotatably attached to said housing; a centrifugal brake comprising a fixed part connected to said housing and a rotatable part connected to said descent shaft; and a rope configured for attachment of said load at two different load attachment portions being separated by a descent length of said rope, said rope being wound around said descent shaft along a winding angle being substantially constant during said braked descent, wherein: said descent shaft directly connected to said rotatable part of the centrifugal brake such that one revolution of said descent shaft translates to one revolution of said rotatable part of the centrifugal brake; said winding angle is at least 360°; and said descent shaft is configured to allow the rope to slide axially along the descent shaft during descent.
