Description
B 1.930 Work Supports with Fail-Safe Function

Fail-safe function
The position of the support plunger is maintained both in the event of pressure drop and a complete pressure loss. This is achieved by a fail-safe, patented clamping of the support plunger.

Application
Hydraulic work supports are used to support workpieces and prevent vibration and deflection during machining. The hydraulic locking occurs together with hydraulic clamping of the  workpiece or independently of it.
Thanks to the fail-safe function, these work supports are particularly suitable for:

  • Manufacturing systems with pallet store
  • Clamping fixtures with workpiece loading via handling systems
  • Transfer lines
  • Automatic manufacturing systems
  • Assembly lines
  • Indexing machines
  • Special machine tools
