SKU: PD-2.6 | HDA-2.6P/L


Pneumatically or hydraulically actuated equipment for examination of vehicle suspension and steering elements up to 2.6 t axle load. Due to 6 different directions of movement the joint play detector is suitable for diagnostic purposes and for periodical technical inspection. The low mechanics of HDA-2.6 allows this type to be installed on inspection pit and lifts.

  • Can be installed on inspection pit, and lifts (HDA-2.6)
  • Longitudinal, lateral and turning movements
  • Different test plate surfaces
  • Examinations by one person with special brake pedal depressor
  • Downward pneumatic connections
  • Downward hydraulic connections (HDA-2.6P) or sideward hydraulic connections (HDA-2.6L)
  • The covering of the moving plate edges provide additional safety for the user
  • When the equipment is turned off, the test plates are fixed, too
