Abstract

A door breaching device comprising:

a longitudinal chassis having a first and a second extremity;a piston assembly located at said first extremity of the chassis, said piston assembly comprising a piston rod, said piston rod having, at a first end, a head and a second end located inside a piston chamber, said piston chamber having two opposite ends, a first end having an opening adapted for the movement of the piston rod therethrough and a second end located opposite said first end; wherein said piston rod is adapted for linear displacement between a first position where the second end of the piston rod is positioned at the second end of the piston chamber and a second position where the second end of the piston rod is at the first end of the piston chamber;a motor operatively connected to a hydraulic pump which is operatively connected to the piston chamber;a control unit for user input, said control unit being operatively connected to the motor;a two-part head assembly comprising: a fixed jaw, attached to the first extremity of the chassis; anda movable jaw, operatively connected to the piston rod of the piston assembly; wherein, in the rest position, the piston rod is in a retracted position to allow the fixed jaw and the movable jaw form a L-shaped extension from the chassis, and upon actuation, the piston rod moves outwardly from the retracted position, the fixed jaw braces the device against an element of a door and frame assembly, while the movable jaw applies a linear force to an opposite element of the door and frame assembly thereby having the movable jaw and fixed jaw form a F-shaped extension from the chassis.
