  • The Rotary Angular System allows you to position the head form between 0° and 90°’s vertically and rotate it 360°’s horizontally.
  • Another kind of penetration headforms can be installed on the base.
  • The Flying Arm (Penetrator) is attached to the drop carriage.
  • The drop carriage (twin wire) releases the penetrator to initiate the test. It is also used to raise the penetrator back into position afterwards.
  • The Velocimeter (Time Gate) is a very precise electronic device that calculates the time it takes for an object to pass in front of an infrared beam a few millimeters before impact. The time in milliseconds and the length of the object are then used to determine the velocity.
  • With the remote control you can set the height and the speed, initiate the test, perform an emergency stop, and activate pre-programmed settings.

The drop carriage for the twin wire penetrator is used to drop the flying arm.

There are two ways this can be done:

  • The first is with the pneumatic system. The Remote Control has a button that causes the drop carriage to release the flying arm.
  • The second is a manual lever. If pulled, it will also release the flying arm.
