Manual flange couplings are primarily developed for tractors and commercial vehicles, e.g. for road construction, forestry and agriculture. They are made of cast iron with spheroidal graphite. To secure trailer components, they have a pin in the coupling jaw that can be used to lock and unlock the coupling manually.
HSM offers 2 variants with bolt lengths: 150mm or 480mm. The advantage of the extended bolt over 480 mm is that the driver can operate it from the driver’s seat and does not have to leave the vehicle.
The simple, manual clutch design is available in three hole patterns:
120 x 55mm, 140 x 80 mm and 160 x 100mm.
