Mechanical Failures
Mechanical breaching can be minimally destructive, through the use of lock picks. This method is relatively slow and requires a trained operator, but does not damage the lock or door. Using specialized tools (i.e.: A-tool, K-tool) a lock cylinder can also be quickly dismantled still in the door and unlocked. This also allows the door to be closed and relocked. Mechanical breaching also includes hydraulic breaching, which uses a special hydraulic ram to bust in the door. The hydraulic ram may be powered manually, pneumatically, or electrically. More dynamic methods (kinetic breaching) use force to break the lock or door. The common methods are to use a lever, such as a Halligan bar or crowbar, or to use a tool to concentrate a large amount of force on the door, such as a sledgehammer, hydraulic jack, or battering ram.

Famous quotes containing the words mechanical and/or failures:
“Industry has operated against the artisan in favor of the idler, and also in favor of capital and against labor. Any mechanical invention whatsoever has been more harmful to humanity than a century of war.”
—Rémy De Gourmont (1858–1915)
“It helps parents to feel better if we remind them of our failures with them! And how they turned out just fine despite our imperfections.... We never get over needing nurturing parents. The more we comfort our own adult children, the more they can comfort our grandchildren.”
—Eda Le Shan (20th century)
