Quick close security door system

A security door closure system for Cruise ships and other similar public entrance points to prevent terrorist attack or ship take-over is needed. Cruise ship passenger and ship provisioning entrance gangplanks pass thru large hydraulically operated shell doors. The gangplank must be removed to close the shell door. The quick close security door system (Door-Gate) is a portable bullet resistant rapid close door system that is placed in conjunction with the gangplank or other entry system which when closed prevents forced entry. A single lever either remotely or manual operated immediately closes the doors which then cannot be forced opened from the entrance side.
