Abstract
A door lock system for a debris tank is disclosed. The system includes a door, a threaded bolt projecting from the door, and a rotary actuator coupled to a head of the threaded bolt for rotating the threaded bolt. In addition, the system includes a cross member spanning the inside of the tank and a nut secured to the cross member, where the threaded bolt and nut are positioned to engage the door to pull and secure the door over an open end of the debris tank by rotating the threaded bolt into the nut using the rotary actuator. A hinge assembly is associated with the door to mount the door to a periphery of the open end of the debris tank for swinging movement of the door between an open and a closed position.
