ABSTRACT:
A pneumatic battering ram is disclosed. The battering ram has a housing, a pressurized air tank, a ramming head, and a pivotable ramming edge. Air released from the air tank into the housing forces the ramming head outward against an enclosure to forcibly open it. Where a slug is inserted into the housing, air released from the pressurized air tank into the housing causes the slug to hit the inner surface of the ramming head, forcing it outwardly against the enclosure.
