#CMT# #/CMT# The pivot has Hirth coupling shaft (7) and two forks (3,4) with Hirth coupling discs (11) as a counterpart and displaceable coupling shaft for direction-bound activation of freewheel (5) and preventing the rotation of the swivel joint in coupled state of shaft. The free ends of forks are displaced by axial displacement of clamping shaft (12), in order to grip between Hirth coupling shaft and Hirth coupling discs, such that the rotation of rotary joint is blocked in one direction through the activation of the directional freewheel lock. #CMT#USE : #/CMT# Pivot with freewheel. #CMT#ADVANTAGE : #/CMT# The rotation of the rear axis of rotation is prevented, so that the overall device remains in specific position. Continuous rotation around the leading rear rotation axis is possible. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an exploded perspective view of the swivel lifting device with switchable Hirth coupling shaft. 3,4 : Forks 5 : Freewheel 7 : Hirth coupling shaft 11 : Hirth coupling discs 12 : Clamping shaft. |
