Product Datasheet

General product description

Test rig and accessories for testing mechanical long-term durability on windows and doors.
The device offers the option to test turn-tile, lift-slide and lift-slide-tilt windows right up to parallel slide-tilt doors, freely actuated or forcibly actuated according to the specified standards.
The test program is taught-in freely via a joystick control element into the supplied PC (teach-in procedure).


On request the following options can be offered:

  • Equipment for connecting pneumatic cylinders
  • Two velocity measuring sensors
  • Connection of up to 3 initiators to control the position of the specimen
  • Increase of handle torque to 75 Nm (incl. optimized gear mechanism and a more powerful motor)
  • Increase of sliding force to 500 N (incl. more stable frame, belt, and bearing)
  • Measuring device for torque and contact force (incl. measurement amplifier, mechanical connection, and data capturing)
  • Measuring device for the sliding force (incl. measurement amplifier, mechanical connection, and data capture)
  • Connection of 10 cylinders with 20 N (incl. cylinders)
  • Freewheel of the handle drive (lockable)
  • Remote maintenance
  • Individual coating

Note: Individual features, especially for your needs, can be provided after consulting.
