8 Captive bolt stunner device
Functional principles of the captive bolt stunner
The energy from the blank cartridge is transferred to the bolt, accelerating
it so that it penetrates the brain of the animal through the skullcap. The in-
tegrated bolt spring and the rubber buer brake the bolt back to a stand-
still and push it back into the device (applies to the models Blitz Kerner
and Kleiner Blitz only).
To achieve optimum results and to protect the device, the energy of the
blank cartridge is tailored to the animal (see chapter 4 – Blank cartridges).
The Bullen Blitz model does not have a bolt spring. A retaining system is
used in this case. This model series was specially developed for the heaver
animals. The device has a larger projection length for the bolt than the
other captive bolt stunner models.
With the Blitz Schlag model series, the method used is the application of a
percussive blow to the head. This device is designed exclusively for stun-
The device is subject to the EC Machinery Directive 2006/42/EC Annex 1,
Point 2.2.2 “Portable xing and other impact machinery.”
The device is to be stored such that it is secured against unauthorized use.
Aer igniting the propellant charge in the cartridge receiver, the bolt acce-
lerates, projects a dened distance out of the sleeve and is then withdrawn
back into the housing (exception: Bullen Blitz), aer which it remains in the
device. Only C.I.P. approved central re cartridges of calibre 9x17 may be
used as propellants. For optimum results, we recommend using turbocut
blank cartridges or products of equivalent quality.
