Ro-4 detonator


- bait, relieving, to secure all types of anti-tank and anti-personnel mines weighing more than 2 kg against their removal.


The Ro-4 detonator is bakelite, waterproof and contains a minimum amount of metal components. Ro-4 can be used for training by adjusting it with a training combined detonator Žk and a 200 g training charge. Due to the fact that this detonator is very sensitive, only very well-trained soldiers can work with it.

TTU:
- length of igniter .................... 73 mm
- width of the igniter .................... 25 mm
- height of igniter .................... 51 mm
- minimum activating force ............. 20 N



The Ro-4 detonator consists of a bakelite body in which the striker with the striker spring is placed in the striking position. The firing pin has a pressed steel tip and is held in the firing position by a safety pin. A button covered with a rubber safety cap passes through the upper wall of the igniter body. Furthermore, the detonator is provided with a detonator screw with sealing washers for holding the combined detonator Žk. The operation of the Ro-4 adjusted by the combined detonator Žk and screwed into the additional charge is ensured by the fact that the detonator button rests on the detonator body with its edge under load and with its lower conical end engages in the cavity of the detonator body in which the firing pin is placed. With the detonator locked, the firing pin is held in the striking position by a safety pin, which rests on the detonator body. After pulling out the safety pin, the firing pin is supported by the pressure of the firing pin spring with its conical part on the conical part of the button.


When lifting the mine with which the Ro-4 is loaded, the firing pin pushes the button up by 3 mm by the pressure of the firing pin spring, the released firing pin is thrown onto the detonator Žk and causes it to explode and a charge is brought from it to detonate. The safety pin cannot be pushed back into the firing pin and therefore the mine made in this way cannot be deadjusted or removed without being activated. Mines secured against Ro-4 against removal must be activated.


Mines secured against Ro-4 against removal must be destroyed on site by the enclosed charge or universal anchor.
